py2cairo安装失败。正在检查“cairo”>=1.10.0:未找到

Question

我正在尝试使用32位python2.7（来自tarball源代码）在我的osx10.5上安装PyCairo（来自python.org网站)以及MacPorts的Cairo1.10.2。所以我在安装“py2cairo”。当我运行python ./waf configure时，我得到

Checking for 'cairo' >= 1.10.0           : not found 

我这里有开罗的档案。。。在

但是我要把哪个目录传递给哪个参数呢？这些看起来与指定cairo库无关：

$ python ./waf --help
  ./options()
waf [commands] [options]

Main commands (example: ./waf build -j4)
  build    : executes the build
  clean    : cleans the project
  configure: configures the project
  dist     : 
  distcheck: checks if the project compiles (tarball from 'dist')
  distclean: removes the build directory
  install  : installs the targets on the system
  list     : lists the targets to execute
  step     : executes tasks in a step-by-step fashion, for debugging
  uninstall: removes the targets installed
  update   : updates the plugins from the *waflib/extras* directory

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -j JOBS, --jobs=JOBS  amount of parallel jobs (1)
  -k, --keep            keep running happily even if errors are found
  -v, --verbose         verbosity level -v -vv or -vvv [default: 0]
  --nocache             ignore the WAFCACHE (if set)
  --zones=ZONES         debugging zones (task_gen, deps, tasks, etc)
  --nopyc               Do not install bytecode compiled .pyc files (configuration) [Default:install]
  --nopyo               Do not install optimised compiled .pyo files (configuration) [Default:install]

  configure options:
    -o OUT, --out=OUT   build dir for the project
    -t TOP, --top=TOP   src dir for the project
    --download          try to download the tools if missing

  build and install options:
    -p, --progress      -p: progress bar; -pp: ide output

  install/uninstall options:
    -f, --force         force file installation

  Installation directories:
    By default, "waf install" will put the files in "/usr/local/bin", "/usr/local/lib" etc. An installation prefix other than "/usr/local" can be given using "--prefix", for example "
    --prefix=$HOME"

    --prefix=PREFIX     installation prefix [default: '/usr/local/']
    --destdir=DESTDIR   installation root [default: '']
    --exec-prefix=EXEC_PREFIX
                        installation prefix [Default: ${PREFIX}]

  Pre-defined installation directories:

  C Compiler Options:
    --check-c-compiler=CHECK_C_COMPILER
                        On this platform (darwin) the following C-Compiler will be checked by default: "gcc"

Answer 1

好吧，这一部分。不得不加上

export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH

在python ./waf configure之前，因为在我的~/.MacOSX/environment.plist文件的PKG_CONFIG_PATH中定义了其他一些路径。在

这是从读日志文件中得到的

然后发现/opt/local/bin/pkg-config --libs cairo正在寻找其他地方（GTK+目录）。一些附加信息here。在设置了PKG_CONFIG_PATH变量之后，我可以进入下一步。在

Answer 2

我的道路是

export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:$PKG_CONFIG_PATH

Answer 3

把“出口PKG的配置配置的配置配置”的“出口-PKG配置的配置配置”的“出口-配置”的“出口-PKG配置”的“出口-配置”中的“出口-PKG-配置”的“出口-包装-配置”的“出口-包装-配置”中的“出口-包装-配置”中的“出口-包装-配置”的“出口-包装配置”中的“出口-包装配置”的“出口-包装配置”的“2.10.1/2.10.1/2.10.1/lib/pkgconfig”配置方面：usr/本地/本地/地窖/匹xman/0.28.0/lib的配置配置配置中的是：usr/本地/本地/地区的是28.0/lib的配置配置：/usr/本地/本地/本地/本地/lib/pkgconfig“

这是唯一帮助我的事。在
