我正在尝试安装p4python，这是Perforce版本控制系统的Python扩展。我正在使用cygwin来实现这一点，因为p4python需要P4 C ++ API（它实际上只是一个包装器），而这又需要g ++（更不用说，Python扩展需要一个C编译器，因此，gcc）。我在Windows 7 64位（不是选择）和Microsoft VS 2008给了我一些相当顽固的问题;我听说使用Cygwin / MinGW可能是更好的选择。我也查找了相关问题，但似乎没有一个问题特别相关。
我能想到的最好的是ld正在寻找这些libs的错误位置，并且我被告知Cygwin不能很好地处理符号链接，但我不确定从哪里开始。请参见下面的终端输出：

提出一个更具体的问题，是在寻找错误的地方还是其他出错的地方，我没有看到？我没有想法。非常感谢任何帮助或指导。

这是我用来将lib文件转换为共享库以便与gcc一起使用的方法：
echo EXPORTS > NAME.def nm NAME.lib | grep ' T _' | sed 's/.* T _//' >> NAME.def dlltool --input-def NAME.def --dllname NAME --output-lib libNAME.a 关于使用Cygwin的更多说明（但我在较旧的32位系统上使用gcc 3，因此YMMV）：
安装gcc-mingw软件包（用于gcc和g ++ 3的mingw的头文件和库）或者使用mingw-w64用于gcc 4.5的新软件包之一。此外，使用选项-mno-cygwin进行编译，以防止将Cygwin链接到可执行文件/库中。对于Python扩展，您可以通过将distutils.cfg文件添加到Lib \ distutils文件夹来永久配置distutils以使用mingw：
[build]
compiler = mingw32 #or mingw64
[build_ext]
compiler = mingw32 #or mingw64
我将C:\cygwin\bin添加到Windows路径（最后将干扰降至最低）并在Windows cmd中进行编译。但是，我必须用实际的可执行文件（即gcc3.exe - ＆gt; gcc.exe，g ++ 3.exe - ＆gt; g ++。exe）替换Cygwin符号链接，因为Windows cmd不理解符号链接。它还没有给我一个问题，编译Python 3扩展，Cython（甚至按需编译pyximport），swig和嵌入Python。

This可能有助于从.lib。
