在雪豹上编译Python的Matplotlib

我花了半天时间在雪豹上为python编译matplotlib。我用过谷歌，找到了这个有用的页面（），但我仍然无法编译它。我在那个页面上看到其他用户的评论，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文件以在顶部包含以下内容：

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"

然后我运行：

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 ...

我迷路了。

根据您的错误消息，您缺少freetype标题。您可以使用系统搜索功能找到它们吗。我不会讲如何使用预构建的包，因为我喜欢从头开始就动手编译。

我刚把它编译好。我在make.osx文件中CFLAGS的include路径中添加了freetype2。现在make.osx的顶部是：

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 -I${PREFIX}/include/freetype2"
LDFLAGS="-arch x86_64 -arch i386 -L${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"

然后我运行了这些命令，它编译并安装得非常完美

sudo make -f make.osx mpl_build
sudo make -f make.osx mpl_install

您应该在matplotlib用户邮件列表中询问这个问题。它由实际的matplotlib开发人员监控，而StackOverflow（AFAIK）则不是

$ python setup.py build

将以下修补程序应用于setupext.py

正如其他地方所建议的，macports在多个体系结构上运行良好，MacOsX+版本允许更新和更多：

$ port search matplot
py-matplotlib @0.99.0 (python, graphics, math)
    matlab-like syntax for creating plots in python

py-matplotlib-basemap @0.99.4 (python, graphics, math)
    matplotlib toolkit for plotting data on map projections

py25-matplotlib @0.99.0 (python, graphics, math)

py26-matplotlib-basemap @0.99.4 (python, graphics, math)

Found 6 ports.

在您的情况下，只需发布：

$ sudo port install py26-matplotlib

Python.org 2.7.1默认使用macosx后端（本机cocoa）：

我混合使用了一些说明。它基本上是通过在OSX的/usr/X11中使用libpng工作的

下载、构建和安装（make-install）freetype2 v2.4.4和zlib v1.2.5。 没有使用make-deps

将setupext.py修改为

module.include_dirs.extend(incdirs)
module.include_dirs.append('.')
module.include_dirs.append('/usr/local/include')
module.include_dirs.append('/usr/local/include/freetype2')
module.include_dirs.append('/usr/X11/include')
module.library_dirs.extend(libdirs)
module.library_dirs.append('/usr/local/lib')
module.library_dirs.append('/usr/X11/lib')

修改make.osx以包含相同的/usr/X11信息，png版本1.2.5是osx 10.6.6当前本机版本

PYVERSION=2.7

PYTHON=python${PYVERSION}

ZLIBVERSION=1.2.5

PNGVERSION=1.2.44

FREETYPEVERSION=2.4.4

MACOSX_DEPLOYMENT_TARGET=10.6

OSX_SDK_VER=10.6

ARCH_FLAGS="-arch i386-arch x86_64"

PREFIX=/usr/local

MACPREFIX=/usr/X11

PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"

CFLAGS="-arch i386 -arch x86_64 -I${PREFIX}/include -I${PREFIX}/include/freetype2 -I${MAXPREFIX}/include -isysroot /Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"

LDFLAGS="-arch i386 -arch x86_64 -L${PREFIX}/lib -L/usr/X11/lib -syslibroot,/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"

FFLAGS="-arch i386 -arch x86_64"

那么标准呢

sudo make -f make.osx mpl_build   
sudo make -f make.osx mpl_install   
sudo python setup.py install

哎呀。。。似乎有效。现在在10.6.6上有了2.7.1版本的Image&MDP&pylab&matplotlib

只要安装libjpeg，图像模块（Imaging-1.7.7）就可以正常工作。我使用了

jpegsrc.v8c

，它看起来很开心。

这个解决方案在OSX 10.8.3上对我有效：

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

---

（值得称赞的是：）

然后我当场得到了答案。

make.osx

将自动下载freetype/libpng/zlib。这个解决方案在osx 10.8.3上对我有效：

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

对于自制：

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