Python numpy / f2py链接库

Question

我正在尝试使用f2py为我的一个fortran程序做一个包装。 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

因此，看来我正在从python库中的文件ccompiler.py获取错误。

该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

由于我是Python的新手，我对解决该问题需要做什么感到有些困惑。 似乎尚未实现此方法。 我只需要执行它吗？ 我该如何实施呢？ 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！

这里没有回答问题，但是它确实说明了一种解决方法（只需直接引用所有* .o文件，而不是将它们放在库中即可）。 而且，这只是一篇非常棒的文章，它解释了有关f2py的一些事情。

在用f2py包装的模块中包括已编译的模块（最小的工作示例）？

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

如果您的库基于单个文件，那将起作用。 如果您的库（更有可能）基于多个文件，则仅包括完整的* .o名称。
