I'd love it if Apple provided this stuff. Are they static libs? What versions do they ship them with -- I don't have OS-X 10.5, and I don't think I have them -- maybe I need to update XCode. freetype comes with X11, which is optional (though installed by default on 10.5). Also, I need libjpeg for PIL, but I guess that's not an OS-X issue. Here's the goal: Be able to easily build and distribute binaries of MPL (and other packages that require require similar libs). These binaries should: (1) Run on any OS-X 10.4+ system (10.3.9 would be nice too) with python.org's 2.5 framework build. (2) Allow packaging up with py2app, to get packages that will run on any 10.4+ system. As far as I know, the only way to do that now is to statically link against universal builds of all the dependencies that Apple does not provide on a stock 10.4 system. The problem is that there doesn't seem to be any standard source of Universal binaries for any of these libs (and the extra build flags required haven't made it into the source of the host projects). Also, it seems a bit silly to have a whole bunch of different packages all working hard to bundle in the same libs. I just built PIL against William's Frameworks, and it was oh so easy -- this after spending quite a few hours trying (and not finishing) getting the required libs built as Universal. We can only use Apple's libs if: They provide static Universal versions or The dynamic libs are there on All 10.4+ OS-X boxes. Maybe we can use more Apple libs for 10.5 only builds.

Otherwise, poke more into setup.py and setupext.py, and remove any references to /usr/local/lib. Indeed, in an older version of MPL that I have handy, it's added in setupext.py.

One more comment: Chris wrote: maptlotlib is the only missing piece of the superpack of modules that I distribute for OSX. The Superpack is great, but please, please, please built it Universal -- if you do that, then we'll solve a lot of distribution issues for OS-X python users everywhere. Yes, it's more pain for you, but the Python packages for OS-X situation is just way too ugly -- we really need to make it cleaner. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

[Matplotlib-users] How do you static link to freetype when building eggs?
I've had an ongoing problem building eggs of matplotlib that are statically linked to freetype. I thought I had it nailed, but evidently I do not. Here is my script: export CFLAGS=-arch i386 -I/Developer/src/libpng -I/Developer/src/freetype/include export LDFLAGS=-arch i386 -L/Developer/src/libpng -L/Developer/src/freetype rm -rf build python setupegg.py bdist_egg The build of freetype in /Developer/src/freetype does not even have dynamic libs built. The basedir dict in setupext.py contains the following entry for OSX: 'darwin' : [] However, when the resulting egg is installed by users, they still get the following error: ImportError: dlopen(/Library/Python/2.5/site-packages/matplotlib- 0.98pre-py2.5-macosx-10.5-i386.egg/matplotlib/ft2font.so, 2): Library not loaded: /usr/local/lib/libfreetype.6.dylib Referenced from: /Library/Python/2.5/site-packages/matplotlib-0.98pre-py2.5-macosx-10.5- i386.egg/matplotlib/ft2font.so Reason: image not found I thought I had my bases covered -- if anyone has some insight here, please let me know. maptlotlib is the only missing piece of the superpack of modules that I distribute for OSX. - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
