在Snow Leopard上为Python编译Matplotlib

Question

我已经杀死了半天，试图在Snow Leopard上编译python的matplotlib。我使用了Google，发现了这个有用的页面（http://blog.hyperjeff.net/?p=160），但我仍然无法编译它。我在该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。

我编辑的make.osx文件包含这个顶部：

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" 

我然后运行：

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 ...

我刚刚输了。

Answer 1

根据您的错误信息，您已经缺少freetype标头。你可以使用系统搜索功能找到它们吗？我不会讲使用预先构建的软件包，因为我喜欢挠挠我的脑海，也从头开始编译。

Answer 2

我刚刚编译。我在make.osx文件中的CFLAGS包含路径中添加了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" 

然后我运行这些命令，它编译和安装完美。

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

Answer 3

你应该真的在matplotlib-users邮件列表上问这个问题。它由实际的matplotlib开发人员监控，而StackOverflow（AFAIK）则不是。

Answer 4

您还可以通过使用

$ python setup.py build 

与下面的补丁建立适用于setupext.py

其他地方建议，MacPorts的工作在多种体系结构和优良的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) 
    matlab-like syntax for creating plots in python 

py25-matplotlib-basemap @0.99.4 (python, graphics, math) 
    matplotlib toolkit for plotting data on map projections 

py26-matplotlib @0.99.0 (python, graphics, math) 
    matlab-like syntax for creating plots in python 

py26-matplotlib-basemap @0.99.4 (python, graphics, math) 
    matplotlib toolkit for plotting data on map projections 

Found 6 ports. 
$ 

在你的情况下，只需发出：

$ sudo port install py26-matplotlib 

其特点是MacOSX的后端（天然可可）作为默认

Answer 6

对于Python.org 2.7.1：

我用的指令的混合。它基本上使用的libpng在OSX的在/ usr/X11

1. 下载，建造和安装工作（make install）并对FreeType2 v2.4.4 &的zlib 1.2.5。 没有使用make deps。

2. 修改后的setupext。PY有

   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') 
   

3. 修改make.osx包括同在/ usr/X11信息，PNG版本1.2.5是OSX 10.6.6当前本地

   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" 
   

4. 那么标准

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

5. Crikey ...似乎工作。现在有10.6.6

图片模块（成像-1.7.7）没关系，只要你安装的libjpeg的作品图片& MDP & pylab & matplotlib与2.7.1。我用jpegsrc.v8c，它似乎很开心。

Answer 7

该解决方案为我工作在OSX 10.8.3：

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