Question

我正在尝试使用swig和setup-file将c ++代码用numpy包装到python。我创建了一个相当简单的swig文件和setup.py，但是当我运行时（在Windows XP上）

python setup.py build -c mingw32

共享库的编译失败。我不知道为什么，所以希望有人可以指出我正确的方向。这是怎么回事： setup-skript应该运行swig，并创建一个包装的goldstein_wrap.cpp。然后调用MinGW，它失败了：

C：\ MinGW \ bin \ gcc.exe -mdll -O -Wall -IC：\ Program \ Python27 \ lib \ site-packages \ numpy \ core \ include -IC：\ Program \ Python27 \ include -IC： \ Program \ Python27 \ PC -c＆gt; goldstein_wrap.cpp -o build \ temp.win32-2.7 \ Release \ goldstein_wrap.o -static-libgcc -static-libstdc ++

包含在C：\ Program \ Python27 \ lib \ site-packages \ numpy \ core \ include / numpy / arrayobject.h：14：0中的文件中，
            from goldstein_wrap.cpp:3059:
C：\程序\ Python27 \ lib中\站点包\ numpy的\芯\包括/ numpy的/ ndarrayobject.h：10：1：

Fehler：在extern«
之前预期的初始化程序
goldstein_wrap.cpp：2954：25：Warnung：»swig_module«definiert，aber nicht verwendet

[ - Wunused可变]

错误：命令'gcc'因退出状态1而失败

我的swig文件如下所示：

%module goldstein

%{
    #define SWIG_FILE_WITH_INIT
    #include "goldstein.h"
%}

/*include numpy typemaps*/
%include "numpy.i"

/*initialize module*/
%init %{
    import_array();
%}

%rename(unwrap2d) phase_unwrapping_func;

/* typemaps for the arrays*/
%apply (int DIM1,int DIM2,float* IN_ARRAY2) {(int ysize,int xsize,float* in)};
%apply (int DIM1,int DIM2,unsigned short* IN_ARRAY2) {(int y1,int x1,unsigned short* mask)};
%apply (int DIM1,int DIM2,float* INPLACE_ARRAY2) {(int y2,int x2,float* out),
                                          (int y3,int x3,float* bcuts),
                                          (int y4,int x4,float* res),
                                          (int y5,int x5,float* diff)}


%inline %{
void phase_unwrapping_func(int ysize,int xsize,float* in,int y1,int x1,
                unsigned short* mask,int y2,int x2,float* out, int y3,int x3,
                float* bcuts,int y4,int x4,float* res, int y5,int x5,float* diff) 
{
    phase_unwrapping(xsize, ysize, in, mask, out, bcuts, res, diff);
}
%}

要真正提供所有信息，我的setup.py：

from distutils.core import setup, Extension

import numpy

try:
    np_include = numpy.get_include()
except AttributeError:
    np_include = numpy.get_numpy_include()

_goldstein = Extension('_goldstein',
                       ['goldstein.i','goldstein.cpp'],
                       include_dirs=[np_include],   #include python dll
                       swig_opts=['-c++'],  #enable c++ wrapping
                       extra_compile_args=["-static-libgcc",
                                           "-static-libstdc++"],
                       )

setup(name='goldstein',
      version='1.1',
      description='Blubb',
      author='Foo',
      ext_modules = [_goldstein]
      )

并且，如所要求的，swig生成的文件的上述行：第2950至2958行：

/* -------- TYPES TABLE (BEGIN) -------- */

#define SWIGTYPE_p_char swig_types[0]
static swig_type_info *swig_types[2];
static swig_module_info swig_module = {swig_types, 1, 0, 0, 0, 0};
#define SWIG_TypeQuery(name) SWIG_TypeQueryModule(&swig_module, &swig_module, name)
#define SWIG_MangledTypeQuery(name) SWIG_MangledTypeQueryModule(&swig_module, &swig_module, name)

/* -------- TYPES TABLE (END) -------- */

第3051至3060行：

    #define SWIG_FILE_WITH_INIT
#include "goldstein.h"


#ifndef SWIG_FILE_WITH_INIT
#  define NO_IMPORT_ARRAY
#endif
#include "stdio.h"
#include <numpy/arrayobject.h>


void phase_unwrapping_func(int ysize,int xsize,float* in,int y1,int x1,
                           unsigned short* mask,int y2,int x2,float* out,
                           int y3,int x3,float* bcuts,int y4,int x4,float* res,
                           int y5,int x5,float* diff) 
{
        phase_unwrapping(xsize, ysize, in, mask, out, bcuts, res, diff);
}

第3059行是包含numpy / arrayobject.h的行。对不起，我应该早点考虑一下......

感谢您对headerfile的提示，这是该文件最后一行的拼写错误。

使用swig使用python / c ++编译错误
