copied!<p>I ran into the same issue. Even after running <code>make.osx</code>, it still complained about <code>_FT_Attach_File</code> being undefined when I imported <code>ft2font</code> from matplotlib. Here's how I tracked down the problem. Hopefully, it will help someone else.</p> <p>Running <code>otool -L ft2font.so</code> yielded:</p> <pre><code> ft2font.so: /Users/jbenuck/mpl_build/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0) </code></pre> <p>Note the absence of any mention of libfreetype! How is <code>ft2font.so</code> supposed to locate the symbol if it isn't linked against it?</p> <p>My next step was to capture the commands used during the build:</p> <pre><code> make -f make.osx PREFIX=/usr/local clean fetch deps mpl_build > output.txt </code></pre> <p>Searching this yielded the command that was used to compile the offending python module. I changed the value of the output file to be one in my local directory and ran it:</p> <blockquote> <p>/Developer/usr/bin/llvm-g++-4.2 -bundle -undefined dynamic_lookup -isysroot / -L/opt/local/lib -arch i386 -arch x86_64 -L/usr/local/lib -syslibroot,/Developer/SDKs/MacOSX10.7.sdk -arch i386 -arch x86_64 -I/usr/local/include -I/usr/local/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.7.sdk build/temp.macosx-10.7-x86_64-2.7/src/ft2font.o build/temp.macosx-10.7-x86_64-2.7/src/mplutils.o build/temp.macosx-10.7-x86_64-2.7/CXX/cxx_extensions.o build/temp.macosx-10.7-x86_64-2.7/CXX/cxxsupport.o build/temp.macosx-10.7-x86_64-2.7/CXX/IndirectPythonInterface.o build/temp.macosx-10.7-x86_64-2.7/CXX/cxxextensions.o -L/usr/local/lib -L/usr/local/lib -L/usr/lib -L/usr/X11/lib -lfreetype -lz -lstdc++ -lm -o ft2font.so</p> <p>ld: warning: ignoring file /opt/local/lib/libfreetype.dylib, file was built for unsupported file format which is not the architecture being linked (x86_64)</p> </blockquote> <p>Bingo! Problem found. I know I have both macports and homebrew installed. Apparently, one of them has a version of <code>libfreetype</code> in <code>/opt/local/lib</code> that isn't compiled for 64-bit.</p> <p>I reran the command with <code>"-L /opt/local/lib"</code> removed which worked without a warning. Copying the resulting <code>ft2font.so</code> into my existing matplotlib installation now allows me to successfully import <code>ft2font</code> from matplotlib.</p>
