Question

我正在尝试使用f2py为我的一个fortran程序创建一个包装器。我的fortran程序使用外部库，当我尝试链接它们时，我收到一个错误说：

gfortran:f77: /var/folders/46/l1mrxgls07s6tpwb6tgpvhpr0000gn/T/tmpPCM7Ne/src.macosx-10.9-intel-2.7/progs-f2pywrappers.f

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/distutils/ccompiler.py", line 777, in find_library_file
    raise NotImplementedError

所以，看起来我从python库中收到文件ccompiler.py的错误。

错误对应于文件中的以下代码行：

def find_library_file (self, dirs, lib, debug=0):
        """Search the specified list of directories for a static or shared
        library file 'lib' and return the full path to that file.  If
        'debug' true, look for a debugging version (if that makes sense on
        the current platform).  Return None if 'lib' wasn't found in any of
        the specified directories.
        """
        raise NotImplementedError

我对解决这个问题需要做些什么感到困惑，因为我是Python的新手。好像这个方法还没有实现。我只需要实现它吗？我究竟该如何实现？我是否需要在进行此更改时重建f2py可执行文件？如果是这样，我该怎么做？

谢谢！

这里没有回答这个问题，但它确实说明了一种解决方法（只是直接引用所有* .o文件而不是将它们放在库中）。而且，它只是解释有关f2py的一些非常好的帖子。

Including a compiled module in module that is wrapped with f2py (Minimum working example)?

f2py -c --fcompiler=gfortran -I. libtest.o -m Main main.f90

如果您的库基于单个文件，那将会有效。如果您的库（更有可能）基于多个文件，只需包含完整的* .o名称。
