在 OS X Snow Leopard 上安装 PyCairo 或 Py2Cairo

Question

尝试在 OS X Snow Leopard 上设置 PyCairo。这个网站上有很多关于它的问题，但我遇到了编译错误，这是我以前从未见过的。

这是我的环境变量...

PKG_CONFIG_PATH=/usr/local/Cellar/cairo/1.10.2/lib/pkgconfig/
PYTHON=PYTHON3

这是我的 WAF 配置的样子：

TeaMac:py2cairo itadmin$ ./waf configure
  ./options()
Setting top to                           : /Users/itadmin/Sites/py2cairo
Setting out to                           : /Users/itadmin/Sites/py2cairo/build_directory
  ./configure()
Checking for 'gcc' (c compiler)          : ok
Checking for program python              : PYTHON3
python executable 'PYTHON3' different from sys.executable '/usr/bin/python'

Checking for program pkg-config          : /usr/local/bin/pkg-config
Checking for 'cairo' >= 1.10.0           : yes
Configuration:

LIBDIR                                   : /usr/local/lib
'configure' finished successfully (0.580s)

这是 $ ./waf build 步骤的肮脏之处：

在以下位置找到了该问题的解决方案：

基本上，您可以通过修改“build_directory/c4che/_cache.py”文件来解决此问题。该问题源于 waf 尝试构建多个不同的 -arch 选项。快速修复 - 注释掉包含“-arch”的每一行，您的构建就会成功。
