Great work! Here's how I'd suggest we proceed.
Let's try to get the newer build system running on your box. I run all
the builds remotely, but I've been planning on enabling the system to
run locally. Just haven't gotten there yet...
Make sure you check out the whole release module from svn. Then, edit
release/packaging/conf/macos-10-ppc: change target_host to:
Then, you'll have to set up ssh authorized_keys for your user to be able
to connect to the local machine without a password. (Yeah, this is
kinda dumb, and that's what I mentioned above about fixing. It's just
that I use all of these scripts to run all the builds for all the
The other thing about my build system is that I use the linux noarch
rpms in the installers (mac, win32, and solaris). This is so I don't
have to rebuild them all the time for each platform. For now, you can
edit the new mac build script (packages_to_include) to only contain
Also, another thing, with the new mac build, I don't rebuild all deps
each time. The new scripts will relocate them... hmm... I'm hoping
install_name_tool and otool will work with fat binaries?
But, assuming it does work, we could just build the glib and the other
needed libraries once and post those builds as zipped up libraries.
(Look in release/packaging/defs/mono-1.1 under the macos-10-ppc sections
for what zip files I've posted and what I download each time).
Then, I think that the appropriate autotools magic needs to happen in
the mono build to take care of the changes. We could do the patch each
time initially, but it'd be better to get it into HEAD. But, if we do
the patching, the actual build is also listed in
release/packaging/defs/mono-1.1 under macos_10_ppc_ZIP_BUILD. We would
probably just download the patches with wget from there and patch before
running ./configure, etc...
So, then we'd run ./build from release/packaging . An example would be:
/build macos-10-ppc mono-1.1 188.8.131.52
Then the new mac build script simply takes files that were built
with ./build (or that are in the def file to be downloaded), lays them
down, and runs the necessary scripts to create the installer.
So, let's first try getting the new system working on your box. It
hasn't really been used outside of my build machine. But, I'm on IRC
(wberrier) and we should be able to get it up and running pretty
