[英]Compiling error with python/c++ using swig
我正在嘗試使用swig和安裝文件將C ++代碼與numpy包裝到python中。 我創建了一個相當簡單的swig文件和一個setup.py,但是當我運行時(在Windows XP上)
python setup.py build -c mingw32
共享庫的編譯失敗。 我不知道為什么,所以希望有人能指出我正確的方向。 這是什么情況:setup-skript會按要求運行swig,並創建一個包裝好的goldstein_wrap.cpp。 然后調用MinGW,但失敗:
C:\\ MinGW \\ bin \\ gcc.exe -mdll -O -Wall -IC:\\ Programme \\ Python27 \\ lib \\ site-packages \\ numpy \\ core \\ include -IC:\\ Programme \\ Python27 \\ include -IC:\\ Programme \\ Python27 \\ PC -c> goldstein_wrap.cpp -o build \\ temp.win32-2.7 \\ Release \\ goldstein_wrap.o -static-libgcc -static-libstdc ++
在C:\\ Programme \\ Python27 \\ lib \\ site-packages \\ numpy \\ core \\ include / numpy / arrayobject.h:14:0中包含的文件中,
from goldstein_wrap.cpp:3059:
C:\\ Programme \\ Python27 \\ lib \\ site-packages \\ numpy \\ core \\ include / numpy / ndarrayobject.h:10:1:
Fehler:»extern«之前的預期初始化程序
goldstein_wrap.cpp:2954:25:Warnung:»swig_module«definiert,aber nicht verwendet
[-Wunused-variable]
錯誤:命令“ gcc”失敗,退出狀態為1
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);
}
%}
為了提供所有信息,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]
)
並且,根據需要,swig生成的文件的上述各行: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);
}
3059行是包含numpy / arrayobject.h的行。 抱歉,我應該早考慮一下...
感謝您對頭文件的提示,這是該文件最后一行的錯字。
