在GCC 4.8上构建Python（2.7）模块失败
我正在尝试使用C API构建Python模块/扩展写入，但它失败了：
% python2 cmath.py build running build running build_ext building 'c_math' extension creating build creating build/temp.linux-x86_64-2.7 gcc -pthread -fno-strict-aliasing -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -DNDEBUG -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/python2.7 -c c_math.c -o build/temp.linux-x86_64-2.7/c_math.o c_math.c:18:5: warning: initialization from incompatible pointer type [enabled by default] {"more", c_math_more, METH_VARARGS, "n + nn Using C API"}, ^ c_math.c:18:5: warning: (near initialization for 'c_mathMethods[0].ml_meth') [enabled by default] In file included from /usr/include/python2.7/Python.h:58:0, from c_math.c:1: /usr/include/python2.7/pyport.h:802:39: error: expected ',' or ';' before 'void' # define PyMODINIT_FUNC void ^ c_math.c:22:1: note: in expansion of macro 'PyMODINIT_FUNC' PyMODINIT_FUNC ^ error: command 'gcc' failed with exit status 1 我试图手动构建没有distutils但我得到相同的错误/警告消息
c_math.c：
#include static PyObject * c_math_more(PyObject *self, PyObject *n, PyObject *nn) { if ( PyInt_Check(n) && PyInt_Check(nn) ) { float cn, cnn, result; cn = PyInt_AsLong(n); cnn = PyInt_AsLong(nn); result = cn + cnn; return PyInt_FromLong(result); } } static PyMethodDef c_mathMethods[] = { {"more", c_math_more, METH_VARARGS, "n + nn Using C API"}, {NULL, NULL, 0, NULL} } PyMODINIT_FUNC initc_math() { (void) Py_InitModule("c_math", c_mathMethods); } int main(int argc, char *argv[]) { Py_SetProgramName(argv[0]); Py_Initialize(); initc_math(); }
和cmath.py：
from distutils.core import setup, Extension c_math = Extension('c_math', sources = ['c_math.c']) setup(name = 'c_math', version = '1.0', description = "c_math setup", ext_modules = [c_math])
我做错了什么？
ps：拜托，如果在c_math.c上存在其他错误（我的意思是gcc没有显示的错误）不要跟我说话，我想自己找错误^^
static PyMethodDef c_mathMethods[] = { {"more", c_math_more, METH_VARARGS, "n + nn Using C API"}, {NULL, NULL, 0, NULL} - } + };
你最后错过了一个分号……
