trouble building C extensions with mingw
I am having difficulty getting disutils to build C extensions using the mingw compiler. After installing mingw (file: MinGW-4.1.0.exe) I followed the instructions described in http://sebsauvage.net/python/mingw.html, using pexports and dlltool as instructed and placing libpython23.a the python installation directory. As was noted in this page, disutils did not have to be tweaked. I then copied example.c and example.i and setup.py to the same folder and from within that directory in a dos prompt ran "python setup.py build -cmingw32 " The result was the following compiler errors: E:\RESEARCH\Modeling\PythonFiles\SWIG test>python setup.py build -c mingw32 running build running build_ext building 'example' extension swigging example.i to example_wrap.c E:\swigwin-1.3.27\swig.exe -python -o example_wrap.c example.i C:\MinGW\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IE:\Python23\include -IE:\Pytho n23\PC -c example_wrap.c -o build\temp.win32-2.3\Release\example_wrap.o example_wrap.c: In function `_wrap_My_variable_set': example_wrap.c:1621: error: `My_variable' undeclared (first use in this function ) example_wrap.c:1621: error: (Each undeclared identifier is reported only once example_wrap.c:1621: error: for each function it appears in.) example_wrap.c: In function `_wrap_My_variable_get': example_wrap.c:1631: error: `My_variable' undeclared (first use in this function ) example_wrap.c: In function `_wrap_fact': example_wrap.c:1648: warning: implicit declaration of function `fact' example_wrap.c: In function `_wrap_my_mod': example_wrap.c:1676: warning: implicit declaration of function `my_mod' example_wrap.c: In function `_wrap_get_time': example_wrap.c:1692: warning: implicit declaration of function `get_time' error: command 'gcc' failed with exit status 1 Can anyone tell me where to go from here? I have been trying to get this to work for three days now... Thanks, -mike
