Python numpy/f2py链接库
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,会出现一个错误,提示:Python numpy/f2py链接库,python,numpy,linker,fortran,f2py,Python,Numpy,Linker,Fortran,F2py,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,会出现一个错误,提示: gfortran:f77: /var/folders/46/l1mrxgls07s6tpwb6tgpvhpr0000gn/T/tmpPCM7Ne/src.macosx-10.9-intel-2.7/progs-f2pywrappers.f Traceback (most recent call last): File "/System/Library

我对解决这个问题需要做些什么感到有点困惑,因为我是Python新手。似乎这个方法还没有实现。我只需要实现它吗?我该如何具体实现这一点?进行此更改时是否需要重新生成f2py可执行文件?如果是的话,我会怎么做
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(直接引用所有的*.o文件,而不是将它们放在库中)。而且,这是一篇非常好的文章,用来解释关于f2py的一些事情
f2py-c--fcompiler=gfortran-I.libtest.o-m 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名称即可。我有同样的问题:我的f2py命令是:
f2py-lc:/pytm/lib-m main-c main.f90
我遵循了这里的说明:实际上,这是一个抽象方法(请参阅)我想f2py或numpy.distutils必须在某个地方实现它。我有完全相同的问题。我试图按照以下指南安装scipy:并抛出此错误。您是如何解决此问题的?可以找到如何使用*.o文件解决此问题的示例
