平台无关的方法来找到libpython的路径（例如，用于cmake） [英] Platform independent way to find path to libpython (e.g., for use in cmake)

问题描述

是否有任何独立于平台的方式来获取python安装的libpython的路径（用作cmake参数）？ sysconfig.get_config_var 给出了一些内容，但是没有一致的方法可以使它正常工作。

Is there any platform independent way to get the path to a python installation's libpython, for use as a cmake argument? sysconfig.get_config_var gives some pieces but there's no consistent way I can get this working.

在OSX上：

• 没有变量包含库的实际基本名称（libpython2.7.dylib）


• sysconfig.get_config_var（'LIBDIR'）返回目录libpython2.7.dylib在（/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib）中



• 编辑：似乎在sysconfig报告符号链接和报告真实路径时存在一些差异。 LIBDIR 实际上确实包含libpython.2.7.dylib，但是我刚刚注意到的是这是/usr/local/Cellar/python/2.7.13_1/Frameworks的符号链接/Python.framework/Versions/2.7/Python。

• No variable contains the actual basename of the library (libpython2.7.dylib)
• sysconfig.get_config_var('LIBDIR') returns the directory libpython2.7.dylib is in (/usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/lib)

• edit: There seems to be a bit of a discrepancy in when sysconfig is reporting a symlink and when it's reporting a real path. LIBDIR does in fact contain libpython.2.7.dylib, but what I just noticed is that this is a symlink to /usr/local/Cellar/python/2.7.13_1/Frameworks/Python.framework/Versions/2.7/Python.

INSTSONAME 指向Python.framework / Versions / 2.7 / Python，该路径的基本名称，但我找不到指向该路径父级部分的变量。

INSTSONAME points to Python.framework/Versions/2.7/Python, the basename of that path, but no variable I can find points to the parent part of that path.

在Ubuntu上：

• sysconfig.get_config_var（'INSTSONAME'）给我起名字库（libpython2.7.so.1.0）。


• 没有变量包含它所在的目录（/ usr / lib / x86_64-linux-gnu /）。
  
  
  
  
  • LIBDIR 仅返回/ usr / lib
  
  
  • sysconfig.get_config_var('INSTSONAME') gives me the name of the library (libpython2.7.so.1.0).
  • No variable contains the directory it's in (/usr/lib/x86_64-linux-gnu/).
    • LIBDIR returns only /usr/lib

    推荐答案

    CMake python模块： FindPythonLibs 和 FindPythonInterp 。

    CMake python modules: FindPythonLibs and FindPythonInterp.

    如果这些方法对您不起作用，只需在调用cmake <$时设置下一个变量c $ c> -DPYTHON_EXECUTABLE：FILEPATH ， -DPYTHON_LIBRARY：FILEPATH 和 -DPYTHON_INCLUDE_DIR：FILEPAT ，有关更多信息，请在此处。

    If those don't work for you just set the next vars when calling cmake -DPYTHON_EXECUTABLE:FILEPATH, -DPYTHON_LIBRARY:FILEPATH and -DPYTHON_INCLUDE_DIR:FILEPAT, for more info look here.

    示例：

    cmake .. -G "Sublime Text 2 - Ninja"
    -DCMAKE_BUILD_TYPE=Release
    -DPYTHON_EXECUTABLE:FILEPATH=d:\virtualenvs\python362_32
    -DPYTHON_LIBRARY:FILEPATH=d:\virtualenvs\python362_32\libs\python36.lib
    -DPYTHON_INCLUDE_DIR:FILEPAT=d:\virtualenvs\python362_32\include
