在Snow Leopard上为Python编译Matplotlib

Question

我已经杀了半天试图在Snow Leopard上为python编译matplotlib.我已经使用了googles并找到了这个有用的页面(http://blog.hyperjeff.net/?p=160),但我还是无法编译它.我看到该页面上其他用户的评论,所以我知道我并不孤单.

我已经独立安装了zlib,libpng和freetype.

我编辑了make.osx文件,将其包含在顶部:

PREFIX=/usr/local

PYVERSION=2.6
PYTHON=python${PYVERSION}
ZLIBVERSION=1.2.3
PNGVERSION=1.2.33
FREETYPEVERSION=2.3.5
MACOSX_DEPLOYMENT_TARGET=10.6

## You shouldn't need to configure past this point

PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="-Os -arch x86_64 -arch i386 -I${PREFIX}/include"
LDFLAGS="-arch x86_64 -arch i386 -L${PREFIX}/lib"
CFLAGS_DEPS="-arch i386 -arch x86_64 -I${PREFIX}/include -I${PREFIX}/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.6.sdk"
LDFLAGS_DEPS="-arch i386 -arch x86_64 -L${PREFIX}/lib -syslibroot,/Developer/SDKs/MacOSX10.6.sdk"

然后我跑:

sudo make -f make.osx mpl_build

这给了我:

export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" &&\
    export MACOSX_DEPLOYMENT_TARGET=10.6 &&\
    export CFLAGS="-Os -arch x86_64 -arch i386 -I/usr/local/include" &&\
    export LDFLAGS="-arch x86_64 -arch i386 -L/usr/local/lib" &&\
    python2.6 setup.py build

... snip ...

我迷失了.

Answer 1

根据您的错误消息,您丢失了freetype标头.您能使用系统搜索功能找到它们吗？我不打算使用预先构建的软件包,因为我喜欢从头开始编写并从头开始编译.

Answer 2

这个解决方案适用于OSX 10.8.3:

ln -s /usr/local/include/freetype2/freetype/ /usr/include/freetype
