py2cairo安装失败。检查“开罗”； >= 1.10.0 ：未找到

Question

我正在尝试使用 32 位 Python 2.7（来自 python.org）和来自 MacPorts 的 cairo 1.10.2 在我的 OS X 10.5 上安装 PyCairo（来自 tarball 源）。所以我正在安装“py2cairo”。当我运行 python ./waf configure 时，我发现

Checking for 'cairo' >= 1.10.0           : not found 

这里有 cairo 文件...

$ ls /opt/local/include/cairo
cairo-deprecated.h          cairo-gobject.h             cairo-script-interpreter.h  cairo-tee.h                 cairo-xlib-xrender.h        cairo.h
cairo-features.h            cairo-pdf.h                 cairo-script.h              cairo-version.h             cairo-xlib.h
cairo-ft.h                  cairo-ps.h                  cairo-svg.h                 cairo-xcb.h                 cairo-xml.h
$ ls /opt/local/lib/cairo
cairo-fdr.0.so*         cairo-fdr.la*           cairo-sphinx.0.so*      cairo-sphinx.la*        libcairo-trace.0.dylib* libcairo-trace.dylib@
cairo-fdr.a             cairo-fdr.so@           cairo-sphinx.a          cairo-sphinx.so@        libcairo-trace.a        libcairo-trace.la*

但是我应该将哪个目录传递给哪个参数？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

  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: '']

Answer 1

好的，明白了这一部分。必须

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

在 python ./waf configure 之前添加，因为我的 ~/.MacOSX/environment.plist 文件中的 PKG_CONFIG_PATH 中定义了一些其他路径。

从阅读日志文件中得到这个

Checking for 'cairo' >= 1.10.0
['/opt/local/bin/pkg-config', '--atleast-version=1.10.0', 'cairo']
not found

，然后意识到 /opt/local/bin/pkg-config --libs cairo 正在其他地方（GTK+ 目录）查找。 此处有一些附加信息。设置 PKG_CONFIG_PATH 变量后，我可以继续下一步。

Answer 2

我的路径是

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

Answer 3

尝试运行“导出PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig:/usr/local/Cellar/libpng/1.5.13/lib/pkgconfig:/usr/local/Cellar/freetype/2.4.10/lib/pkgconfig:/usr/local/塞拉r/fontconfig/2.10.1/lib/pkgconfig:/usr/local/Cellar/pixman/0.28.0/lib/pkgconfig:/usr/local/Cellar/cairo/1.12.8/lib/pkgconfig:/opt/local /lib/pkgconfig”

这是唯一对我有帮助的事情。

我遇到了与您相同的问题，但是在执行此配置后成功完成！
