Python numpy/f2py 链接库

Question

我正在尝试使用 f2py 为我的一个 fortran 程序制作一个包装器。我的 Fortran 程序使用外部库，当我尝试链接它们时出现错误消息:

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 库中的文件 ccompiler.py 中得到了错误。

错误对应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

由于我是 Python 的新手，我对解决这个问题需要做些什么感到有点困惑。好像这个方法还没有实现。我只需要实现它吗？我究竟该如何实现呢？进行此更改时是否需要重建 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，但它确实说明了一个解决方法(直接引用所有 *.o 文件而不是将它们放入库中)。而且，这只是一篇解释有关 f2py 的一些事情的非常棒的帖子。

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，那么这将起作用。如果您的库(更有可能)基于多个文件，只需包含完整的 *.o 名称集即可。
