Hi,

I have installed mono-1.2.6, mod_mono-1.2.6 and xsp-1.2.6 on suse linux 9
system with apache 2.2.8 from source. So far everything is fine except I
always get " File exists:Failed to create shared memory segment for backend

don't have any problem with my mono web application. I'm wondering if
anybody can shed some light on this problem.

Thanks.

Subject: [Mono-list]  mono-service, mono-service2
Message-ID: <15779110.post@talk.nabble.com>


This question is perhaps less about mono-service, and more about the .NET
ServiceProcess. The benefits are auto-startup, restart on failure, logging,
etc.  

Does hosting my application within a Windows Service (ServiceProcess) buy me
anything else? Like thread handling, concurrent connections, or do I need to
implement those myself?

Within the context of mono under Linux, how does mono-service interact with
the OS. In other words, how do I define the startup/authentication/logging
for mono-service.

I realize the question is vague, so if anyone can provide a few links, or
even key-words to google, I'd appreciate it. Thanks in advance.

PROJECT DETAILS:
I'm running a message-receiver on linux, which accepts an ant project and
invokes it. With regards to the transport, I considered running an xsp/xsp
web service. But some of the processes I'm running are massive, consume
loads of cpu/memory and can take hours to run. I don't want to invoke them
within a web-application, though if anyone disagrees with this concern I'll
gladly stand corrected.  Its the sort of thing that WCF is intended to
handle, but that's not an option right now. 

At this point mono-service seems like the best option, but I'm not sure.

You have to implement all these features yourself.

Startup services are not part of mono-service. You must provide your
own startup scripts. Search the list for samples, as this topic has
been already discussed a couple of times.

I'd host those jobs inside their own XSP process (to decouple them from
the web site [if any]) and access them via Web Services.

Another approach is using a service + remoting for IPC.

Message-ID: <15c45fbc0803031431m1aab0248qeb639845d29105c4@mail.gmail.com>

I've installed Mono on OS X and compiled and installed mod_mono from
source (./configure && make && make install) which has all gone
smoothly but I'm having some trouble launching Apache.

I've gone the AutoHosting route and added "Include
/etc/apache2/mod_mono.conf" to my httpd.conf file but with this line
Apache wont launch. If I remove the line then Apache loads fine but
not when it's included.

The error I'm getting in the logs is this:

03/03/2008 22:25:33 org.apache.httpd[59793] httpd: Syntax error on
line 485 of /private/etc/apache2/httpd.conf: Syntax error on line 8 of
/etc/apache2/mod_mono.conf: Cannot load
/usr/libexec/apache2/mod_mono.so into server:
dlopen(/usr/libexec/apache2/mod_mono.so, 10): image not found

Now, /usr/libexec/apache2/mod_mono.so definitely exists. To prove it,
this is the output from "sudo find / -name mod_mono.so":

darrells-imac:~ Darrell$ sudo chmod 7777 /usr/libexec/apache2/
darrells-imac:~ Darrell$ sudo find / -name mod_mono.so
/Users/Darrell/Downloads/mod_mono-1.2.6/src/.libs/mod_mono.so
/usr/libexec/apache2/mod_mono.so

Does anyone have any idea what I could have done wrong?

Kiwi (the system which creates our vmware image) uses qemu-img to create
the disk image.  qemu-img cannot create or convert to a scsi vmdk type.
Also there are no other tools to convert from an ide disk to scsi.

Thank you for the suggestion.  Sorry for taking so long to get back to

If you install VMware Server (or even Player, I think), it comes with:
vmware-vdiskmanager.exe, which I believe can convert IDE disks to SCSI. If
you do that manually, you need to change the vmx file to point to the SCSI
disk instead of IDE.
Does SCSI support sound like a feature request for Kiwi/qemu-img, given its
high level goals?

I'm basically asking for references on how to do this using mono (if

Check out iTextSharp, it's a port of the java pdf creation library to .net.
It may or may not work with mono, I've not tested it.

I'm assuming that I need the Mono core compiled with

Which on of the tarballs at

winform code for me to compile?

This question crops up once in a while.

What we do here, is to create a svg file (this is basically XML, and we create 
it from a template), which we then run through a svg to pdf converter. We use 
inkscape, which can run headless, and can be used under both Windows and 
Linux.

We actually design the templates in inkscape too, then have a program to 
convert the svg files from inkscape into templates by using annotation.

Getting it all to work was a bit of work, but that is mostly because of the "a 
slightly above average it knowlegeable secretary should be able to design a 
new template" step.

Subject: [Mono-list] Problem with loading native libraries
Message-ID: <47CE8B75.2050505@frisch.fr>

Hello,

I'm new to Mono, so please redirect me to a more appropriate forum if
this mailing list is not appropriate for such questions.

I've a function defined in a native shared library "csml_native.so" that
I'd like to call from Mono. In C#, I define a method with
DllImport("csml_native.so"). However, when the method is called, I get
an unhandled exception:

  System.DllNotFoundException: csml_native.so

Setting the environment variable MONO_LOG_DEVEL to debug as explained on
www.mono-project.com/DllnotFoundException does not produce any output
(I'm using Mono 1.2.4 packaged in Ubuntu).

So I've straced the process and grepped for csml_native. Here's how it 
starts:

> open("/home/frisch/mlfi/applications/csml/test/csml_native.so", O_RDONLY|O_LARGEFILE) = 9
> readlink("/home/frisch/mlfi/applications/csml/test/csml_native.so", 0xbf8736cf, 4096) = -1 EINVAL (Invalid argument)
> open("/lib/tls/i686/sse2/cmov/libcsml_native.so.so", O_RDONLY) = -1 ENOENT (No such file or directory)
> open("/lib/tls/i686/sse2/libcsml_native.so.so", O_RDONLY) = -1 ENOENT (No such file or directory)
> open("/lib/tls/i686/cmov/libcsml_native.so.so", O_RDONLY) = -1 ENOENT (No such file or directory)
 > ...

As can be seen, mono finds the .so file (in the current directory). For 
some reason it seems to interpret it as a symbolic link (though this 
seems to be the case also for managed assemblies that it successfully open).

Here are the lines immediatly after the successfull open:

> open("/home/frisch/mlfi/applications/csml/test/csml_native.so", O_RDONLY|O_LARGEFILE) = 9
> fstat64(9, {st_mode=S_IFREG|0755, st_size=988763, ...}) = 0
> mmap2(NULL, 991232, PROT_READ, MAP_PRIVATE, 9, 0) = 0xb6ee6000
> mprotect(0xb6ee6000, 991232, PROT_READ|PROT_EXEC) = 0
> readlink("/home/frisch/mlfi/applications/csml/test/csml_native.so", 0xbffca61f, 4096) = -1 EINVAL (Invalid argument)
> close(9)                                = 0
> munmap(0xb6ee6000, 988763)              = 0


Here's the output of ldd on the .so file:

>         linux-gate.so.1 =>  (0xffffe000)
>         libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7e9a000)
>         libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7e96000)
>         libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7d4b000)
>         /lib/ld-linux.so.2 (0x80000000)

Any idea what I'm doing wrong?

Message-ID: <325919950803050550q2e412729k4025fcd251bbc08a@mail.gmail.com>

Hello everyone,

I'm a a final year student at the university of Portsmouth in England, I'm
currently doing a project on cross-platform development using VB and Mono
and I was wondering if anyone would be willing to share any stories or
comments on their experiences using Mono, using VB to develop applications
using Mono or any errors or bugs encountered and how they where overcome.
Any information would be helpful and would be gratefully received.

thanks for any help,

John Walker.

Message-ID: <4ff60e1c0803050946u45092f48t158e9005cd7ddfa4@mail.gmail.com>

Hi,

I'm trying to use the Mono.Cairo namespace with the Glitz backend, but
am having some difficulties, and was unable to find a good reference
on the topic. There's a good page on the Mono website about using
Cairo[1] but it doesn't address Glitz. Can someone point me to the
right docs?

I'm stuck in a very basic issue right now, ie, how to create a
GlitzSurface object? :)
I've also checked Mono's class library reference[2], but it didn't help much.

Thanks,
Filipe Correia

Hi,

A project that I'm involved with has a requirement to provide a GUI with database connectivity to users while running in WinPE 2.0 (the preboot environment released with Vista). This can be done today in MFC/C++ (hard) but I'd much rather work in C# and WinForms (easy).

Can anyone provide instructions on what is necessary to manually install Mono in a Windows environment? I only need the runtime environment of Mono and I cannot use the installers provided by Novell.

Thanks!!
Michael

Use the Windows Installer on a test/development
machine.  Install to a path like C:\mono-1.2.6

Do not install in a path like C:\Program
Files\Mono-1.2.6

Zip up the results.  

The problem with a manual install is that the
installer generates scripts based on your installation
path.  The installer also generates the proper
pkg-config pc files found at in your
mono_install_path\lib\pkgconfig

And last, the installer adds a registry key for
novell/mono so 3rd party applications can find the
default mono installation.  The installer may add a
registry key for gtk+ and gtk# as well.

With understanding the above, copy the zip file to
another test machine.  Unzip and try to run on mono on
the 2nd test machine.

This is where virtual machines will come in handy for
you.  You create a virtual machine once.  For each
test, copy the virtual machine file, start the virtual
machine, copy over and unzip mono, test mono.

Subject: [Mono-list] Threading and IO problem
Message-ID: <a8051c180803060950j6660baf4h8adbb7454ffff8ed@mail.gmail.com>

I've made a small program to use all processors on a system to analyze N
text files. But when it's run on a 8 CPU PC, the CPU time stays around
70%-80% and the idle time between 20-30%.

I  made a small program to illustrate the problem, it was simplified it to
the point it doesn't process anything. It just creates a thread for every
processor on the system and every thread just reads an entire file passed as
parameter:
------------------------------------
using System;
using System.IO;
using System.Threading;

namespace MultipleReader
{
    class Program
    {
        static void Main(string[] args)
        {
            Thread[] Threads = new Thread[Environment.ProcessorCount];
            for (int Idx = 0; Idx < Threads.Length; Idx++)
            {
                MyThread T = new MyThread(args[0]);
                Threads[Idx] = new Thread(new ThreadStart(T.Process));
            }
            foreach (Thread T in Threads)
                T.Start();
            foreach (Thread T in Threads)
                T.Join();
        }
    }

    class MyThread
    {
        private string FileName;

        public MyThread(string FileName)
        {
            this.FileName = FileName;
        }

        public void Process()
        {
            string Str;
            using (StreamReader SR = new StreamReader(FileName))
                while ((Str = SR.ReadLine()) != null) ;
        }
    }
}
------------------------------------
When this program is run using a large text file as a parameter (a ~600 megs
file, to make the reading last in the order of tens of seconds) the same
behavior is observed. Is this normal? What is causing this behavior? Is
there any way to use all the processors at full capacity?

The file is fully cached (cat file /dev/null) on RAM (4G RAM on this PC)
before the program is started.

What does top or vmstat tell you?  Are you getting IOWait?  System CPU?

Do you have 8 CPUs or 8 cores?

Multicore processors often have to compete for the memory bandwidth -
on one project we had to move from quad-core to multiple dual-core
because of this.

Seeing the stats, it seems I overestimated the CPU use.  It's even
lower than I thought (60..70% instead of 70..80%)

I suspect it could be the GC. but I don't know any way to corroborate
this suspicion.  This statement:

     while ((Str = SR.ReadLine()) != null) ;

should create 2.5+M strings (for the file I'm using to test this) for
every thread so the GC must be called many times.

Any way to corroborate this? Any workaround to use the all the CPU
power available?

That's only 4 real execution units.  You're getting the extra smidgeon
of performance that HT gives in the best case, but there just aren't 8
cores there.  Getting real quad core chips (Harpertown) will likely
mean you can get to full 8 core usage.

If you turn off HT in the BIOS (if such a thing is possible on a Dell)
you would probably see 100% utilization.  But you're getting what I'd
be inclined to call 120% right now, so unless you want to confirm that
this is indeed the case, I'd just leave it alone.

                        x+=1;
                else

So it seems some kind of bottleneck when "new StreamReader(FileName)" get
produced
with file opening etc..
But my system shows CPU load like for real processors.

Your problem is that you need to ensure your threads get launched, and
run, on each available processor. As you may have guessed, your best
processor utilization will occur with 8 threads in execution on an 8-way
box.

In version 2.0 of the .NET Framework MS developed an elegant solution
for this. Instead of creating your own threads, you can call
ThreadPool.QueueUserWorkItem and pass it a delegate to a static
function. This will take complete responsibility for allocating threads
from the thread pool, and getting them executed on separate processors.
Your overall CPU utilization will shoot up to 100.

I don't know if this is implemented in Mono.

Hi,

>From my (bad) memroy, ThreadPool is implemented. There is only a small
difference between default number of thread pool.

By using ThreadPool, you can't have a direct pointer on the launched Thread,
so you will have to deal with other concurency management (Semaphore, mutex,
or other waithandle) to wait for all task to be completed.

I may be wrong, but reading lots of files at the same time, can the hard
drive support the required bandwith ?

Best regards,

Damien

Message-ID: <3b36cbf20803040253w5d6cf4ddg865b89fdee67500e@mail.gmail.com>

Hi,

I've googled around but i couldn't find any information regarding mod-mono
configuration on the subject. My goal is to set up our mod-mono-server to
accept requests from a host even if that same host just downloads a file.
The current sitation is that if a user starts a download, the ajax user
interaction stops until the download finishes.

Any ideas?

Thx,

I have this exact same problem. Only It's a tiny .net 2.0 project built in vs2005 running on win 2003. I also get nothing but a blank page. Are there any additional settings that needs to be done? Did you solve this?

------------------------

I can't run any ASP.NET page under XSP2.

All test made under WinXP 64Bit, site developed in VS2008 and published 
with "Publish" menu item.
.......
I've got only empty response and see empty white page without any errors.

I don't think this is a problem with mod_mono / mod-mono-server. There 
are no limitations like that in the life cycle of a request. (Well, I 
don't know about the ASP.NET internals but I doubt it. Definitely not in 
Apache, mod_mono, or mod-mono-server.) Each request is handled entirely 
separately.

It might be a client-side issue- a maximum number of concurrent requests 
you allow your browser to send to the same server.

(Under high load it could be a server-side issue too, of course.)

Sorry I'm not more helpful.

 Yes, I know I won't get the same processing power of 8 real
 processors. Nevertheless the OS should occupy the 8 logical processors
 to the full extent with no idle time. That isn't happening when I run
 this program. But it does happen when I do some other stuff, e.g. when
 I'm compiling the kernel with "make -j8 ...". The problem seems to be
 that the threads (for a reason I don't know yet) block for little
 periods of time. There are no other runnable process interfering here,
 because there is idle time left.

 There is no IOWAIT either, so the HDs are not the bottleneck (3 disks
 raid5 10Krpm). The file is cached on memory completely so there is no
 HD access (visually confirmed -the HDD LEDs almost doesn't blink
 during the program run-, besides the stats posted earlier showed it
 too).

 Besides, the example I posted is not equivalent of the original
 program I'm developing. That program uses a shared object that feeds
 the threads 10k lines at a time. With that scheme, the processor usage
 was around 75-80%. This is another reason that makes me think the GC
 is involved.

 Tomorrow (It's almost 5pm here in Cuba) I will try a different
 approach (instead of using threads, I will use processes to isolate
 the GC effect to one thread)

 Well I just manually created the same number of threads as the number
 of processors on this system. The OS should run them on an available
 processor and on this PC the processors are idle almost always. This
 is happening so there is no problem on this front.

 the system has 4G of RAM, The file was fully cached before (cat file
 /dev/null) the program was run. This was the first suspect, of course,
 but no, this is not the cause.

Good idea. Hyperthreading almost never works well. Intel had a good idea there. but the theoretical advantage is small, and by faking the OS into thinking you have full extra cores it causes the execution threads to be allocated poorly. 
 
True multicore processors don't have this problem (all the new chips are good). They have full extra cores and each core can run a separate thread. I don't think Intel is still making new Hypercore CPUs (at least I hope not).

Hi,

My guess is that your threads are waiting for the data to load from the
system memory to the processor cache.  If you do the same test with a small
file (one that would fit in the CPU cache), and read the file multiple
times, I'm pretty sure that the CPU usage would go up.

 Yes, I know I won't get the same processing power of 8 real  processors.
Nevertheless the OS should occupy the 8 logical processors  to the full
extent with no idle time. That isn't happening when I run  this program. But
it does happen when I do some other stuff, e.g. when  I'm compiling the
kernel with "make -j8 ...". The problem seems to be  that the threads (for a
reason I don't know yet) block for little  periods of time. There are no

10k lines at a time. With that scheme, the processor usage  was around

Top is showing some artifacts  when is measuring the individual CPU
time (that's normal).

look at the aggregated CPU usage (3rd row on each sample): 0.0%id

Ok, then there is one question left: is there any way to program this
using threads without the GC interfering? any ideas?

It looks like the GC needs a little manual tuning for your app.
For a 600 MB file on a dual core with 2 threads running a good
default seems to be setting an initial heap size of 10 MB:
	GC_INITIAL_HEAP_SIZE=10000000 mono yourprog.exe
With 4 threads (which is sort of equivalent to 8 threads on a 4 cpu
hyperthreaded box) you need about 20 MB, but try also with more
and measure what's best for your workload (and please report back your
results).

On Linux you can read the /proc/meminfo file which contains stuff like:
MemTotal:      2067116 kB
MemFree:        191708 kB

The multiprocess version is still the best. And it is a pity. The
original program queries a DB, with a multithread version all threads
can share a cache, and only query the DB the first time an ID is
needed. I can't do that with a multiprocess program just as easily.

OTOH and as a curiosity: Is there any way to free memory directly (at
CIL level I mean) without using the GC? for instance:

   while ((Str = SR.ReadLine()) != null) ;

with a little flow analisis we can determine Str isn't used after it
is assigned. is there a way to deallocate it efficiently without
waiting for the GC to collect memory?

Best regards

>From what I understand, most http clients are supposed to limit
themselves to 2 connections to a single server at a time.  To avoid
that, many sites (like google maps) use multiple subdomains handle the
requests.  This is why you will see domains like mt0.google.com and
mt1.google.com during google maps usage.  Hope that helps.

Subject: [Mono-list] ASP.NET Forms Authentication
Message-ID: <481885.98350.qm@web51612.mail.re2.yahoo.com>

I can't get forms authentication to work under XSP
2.0.  I'm using the following code in my login button
click event handler if the login entered is correct:

FormsAuthentication.Initialize();
String strRole = assignRoles(loginTextBox.Text);

//The AddMinutes determines how long the user will be
logged in after leaving
//the site if he doesn't log off.
FormsAuthenticationTicket fat = new
FormsAuthenticationTicket(1, loginTextBox.Text,
DateTime.Now, DateTime.Now.AddMinutes(30), false,
strRole, FormsAuthentication.FormsCookiePath);

Response.Cookies.Add(new
HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)));

Response.Redirect(FormsAuthentication.GetRedirectUrl(loginTextBox.Text,
false));

In the Web.config file I have:
<location path="Protected">
  <system.web>
    <authorization>
      <allow roles="admin"/>
      <allow roles="stduser"/>
      <deny users="*"/>
    </authorization>
  </system.web>
</location>

<authentication mode="Forms">
  <forms name="login" 
             loginUrl="LoginPage.aspx" 
             defaultUrl="Default.aspx" 
             protection="All" 
             timeout="30" 
             path="/" 
             requireSSL="false" 
             slidingExpiration="true" 
             cookieless="UseDeviceProfile" 
             domain="" 
             enableCrossAppRedirects="false"/>
</authentication>

<authorization>
  <allow users="*"/>
</authorization>

This works with VS 2005 and the ASP.NET web dev
server.  Why doesn't this work with Mono's XSP 2.0 web
server?  Is there something I can change to make sure
this works?

NOTE: I'm using Mono 1.2.6 under Windows Vista x64 but
plan to move this to a Linux Apache web server once I
have it working on Windows.  Surely this doesn't make
any difference though...

Thanks,
Kevin.

Thanks Robert for helping me out with my last Mono/Monorail question.
Using Mono 1.9 did seem to fix the last problem.  However, running
under Mono 1.9b4 and XSP2 I get the following error:

Server Error in '/' Application

Unices use a different path separator: have you tried timecard/addtime?

I would assume that Monorail is doing the correct routing for the
request.  I point my browser to
http://localhost:8088/timecard/addtime.rails, and I get that error.
There actually isn't a file addtime.rails, so I'm not sure why this
happens.

This would also have to be determined for the ReadLine() method
(making sure it doesn't stash a reference somewhere) as well as any
methods that ReadLine() passes that string reference to (which may be
none, but you get my point).

I have often wished for the same thing, but implementing it is
considerably more complicated than it looks.

Subject: [Mono-list] SocketException
Message-ID: <4064cf4d0803091719t72e9d739w440abc8ec0c5210f@mail.gmail.com>

Hi all,
I am new to mono.
I am tried to run a program.And it threw this exception

Unhandled Exception: System.Net.Sockets.SocketException: No such host is
known

The program works fine in when I run it with mono in windows but not with
mono in Ubuntu.

Can anybody tell me what I am doing wrong?

Yes, I know. When I asked about it I was thinking of a way for the JIT
to rely on the compiler to do this analysis, and don't waste JIT
compilation time on this matter. I mean, to successfully  implement
this, there must be a way to tell the runtime this object won't be
used in the future without it having to wait for the GC to extract
this knowledge from the live object references.

This would allow to:
* convey more information of the object usage to the runtime. The
runtime could use this information to detect incorrect programmer
assumptions ("This object is of no use at this point, so the GC will
collect it..") about the program behavior (for instance in debug mode,
this could be treated as a hint). See for example bug
#357649(https://bugzilla.novell.com/show_bug.cgi?id=357649). I assume
(from comment #3) the library programmer thought no one was using the
input stream at his point (when a "Process" object is finalized), so
let's close it. There is no way to assert this information ("there is
no reference to this stream") to the runtime (at least I don't know
how to do it). Result: this particular error. This would also help to
detect unexpected "... stashed references somewhere" (memory leaks in
many cases ;-) which is a good thing I suppose.
* lessen the pressure on the GC (using some invocation switch to the
runtime) to treat these hints as deallocations.
* anything in between.

If the runtime doesn't help with this, this would only be possible at
JIT time (or at AOT compilation with a little extra support from the
mono runtime).

Well to much daydreaming for today, back to work

Best regards
      Yanko

vmware-vdiskmanager cannot convert from IDE to scsi.  I don't know about
qemu-img supporting scsi some day.  It would be worth asking them but I
doubt it would be important as they have their own disk format.

Another reason this is not likely to happen is that IDE and SCSI disks
use different geometries (at least that's what the error message in
vmware says) and converting a disk image to a different geometry would
require changes to the partition table.

Subject: [Mono-list] Nant / Osx
Message-ID: <2D3C3EC6-29A1-4DA5-967F-CFCE4BC4E668@moga.to>

Hi all,

I've been having some troubles building my project under osx 10.5.2.   
Our project is normally compiled via a Monodevelop solution which has  
always worked fine - I'm just trying to get it to compile on my laptop.

I've written NANT scripts to build all of the different projects but  
have had trouble with:
1) Gdk - I use it for image resizing.  I have to have a reference  
directly to the gdk-sharp-2.0 alias -

				<include name="/Library/Frameworks/Mono.framework/Libraries/mono/ 
gtk-sharp-2.0/gdk-sharp.dll"></include>
				<include name="/Library/Frameworks/Mono.framework/Libraries/mono/ 
gtk-sharp-2.0/glib-sharp.dll"></include>

Now I vaguely remember seeing a tutorial about using pkg-config to  
create a link to the dlls so that they can be easily referenced but  
couldnt find it when i looked today? Is there some way to get the NANT  
script to add mono package references instead?

2) When I actually run the app, it bombs out saying that it cant find  
the dll -

@@@ Failed to startup GDK - System.DllNotFoundException:  
libglib-2.0-0.dll
   at (wrapper managed-to-native) GLib.Marshaller:g_malloc (uintptr)
   at GLib.Marshaller.StringToPtrGStrdup (System.String str) [0x00000]
   at GLib.Argv..ctor (System.String[] args, Boolean add_program_name)  
[0x00000]
   at Gdk.Global.InitCheck (System.String[]& argv) [0x00000]
   at Mogato.Services.GdkResamplingService..ctor () [0x00000]

This is a concern, any comments?

3) I have similar issues for System.Runtime /  
System.Runtime.Serialization dlls as number 1.

So really I'm just having some troubles with packages / references as  
Monodevelop magically handled them for me before which is great but  
now I need to understand a little more myself.  Any pointers or ideas  
anyone?

Cheers,
Mike Cleaver

FYI, I can compile under Monodevelop / Osx ok (as it handles reference  
packages) but point 2 is still a problem.  My laptop is a 1ghz g4 so  
MD doesn't run well enough and I'd prefer to use tm/vi.

You can use the <pkg-references> element for this purpose:

<csc ....>
    <sources>
        <include name="**/*.cs" />
    </sources>
    <pkg-references>
        <package name="gtk-sharp-2.0" />
    </pkg-references>
</csc>

Hope this helps,

Gert

This works with VS 2005 and the ASP.NET web dev
server.  Why doesn't this work with Mono's XSP 2.0 web
server?  Is there something I can change to make sure
this works?

NOTE: I'm using Mono 1.2.6 under Windows Vista x64 but
plan to move this to a Linux Apache web server once I
have it working on Windows.  Surely this doesn't make
any difference though...

Subject: [Mono-list] C# script editor
Message-ID: <016b01c88394$4322c610$7b01a8c0@acer>

I'm looking for a open source C# script editor to be embedded to MONO 2 
application.

I found SyntaxBox  in 
http://www.puzzleframework.com/wikiengine/WikiPageViewer.aspx?ID=90  (last 
link).

SyntaxBox uses DllImports in 3 files (NativeMethods.cs, AutoListForm.cs, 
InfoTipform.cs) , code shown below.

What to you think which is best way to solve this:

1. Change SyntaxBox source code not to use direct WinAPI calls when running 
under MONO.
Is it possible/reasonable to try it to port this MONO ?

2. Use Scincilla or FireBall Editorcontrol.

3. Create new implementation form scratch.

Andrus.
