Here are instructions for building a universal matplotlib for MacOS X from source. The topic comes up once in awhile and having just fought through it, I figured it was best to post instructions. Thanks to Charlie Moad and mpsuzuki for their valuable assistance.
1) Install the prerequisites: 1.1) libz is included with MacOS X 10.4. If you ever installed a copy yourself, get rid of it or make sure it's universal. 1.2) Install libpng. Get source, unpack and: - Configure it for a universal build. On a PPC system (this should be two lines; you may have to manually unwrap the first line): $ CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc" \ ./configure --disable-dependency-tracking - On an Intel system use this simpler version: $ CFLAGS="-arch i386 -arch ppc" \ ./configure --disable-dependency-tracking - Build and install as usual: $ make $ sudo make install - If you plan to redistribute matplotlib, delete the dynamic library so matplotlib statically links to libpng: $ sudo rm /usr/local/lib/libpng*.dylib 1.3) Install freetype. Do *NOT* use version 2.2.1; it is broken on MacOS X (but fixed in CVS). 2.1.10 works fine. Get source, unpack, and install exactly as for libpng except: - Before building, you may wish to modify include/freetype/configure/ftoption.h to enable hinting: uncomment #define TT_CONFIG_OPTION_BYTECODE_INTERPRETER perhaps comment out #define TT_CONFIG_OPTION_UNPATENTED_HINTING - After building, you *MUST* delete the dynamic library. At least for version 2.1.10 and 2.2.1 it is *NOT* universal, only the static library is universal. $ sudo rm /usr/local/lib/libfreetype*.dylib 2) Make sure you have a universal python installed, e.g. MacPython from <http://pythonmac.org/packages/> 3) Install matplotlib in the usual fashion: $ python setup.py build $ sudo python setup.py install (I didn't try easy_install, but I suspect it works too) -- Russell P.S. The instructions for running configure to get a universal binary are from Apple Tech Note 2137: <http://developer.apple.com/technotes/tn2005/tn2137.html> with the correction that LDFLAGS must *NOT* be defined (issue number 4387241 in Apple Bug Reporter database). Fortunately it is not necessary, and suggesting otherwise is a mistake in the tech note. If you forget --disable-dependency-tracking you'll get error messages saying you have an incompatible set of compiler flags. ------------------------------------------------------------------------- Take Surveys.
