我正在为该项目使用 TDM-GCC-64。这是最小的源代码（完整的源代码包括 Python 模块初始化的代码）：

// minimal.cpp
#include <Python.h>

extern "C"
{

static PyObject * f() {
    PyObject * tuple = PyTuple_New(2);
    PyTuple_SetItem(tuple, 0, PyLong_FromLong(0L));
    PyTuple_SetItem(tuple, 1, PyFloat_FromDouble(0.));
    return tuple;
}

}

int main()
{
  f();
  return 0;
}

并且Makefile（原始规则将代码编译成.so文件）：

ANACONDA_PKGS = C:/Anaconda3/pkgs
PY_INCLUDE = -I$(ANACONDA_PKGS)/python-3.5.2-0/include
PY_LINK = -L$(ANACONDA_PKGS)/libpython-2.0-py35_0/libs -lpython35.dll
CXXFLAGS = -fPIC -fopenmp -O3 -std=c++11 $(PY_INCLUDE) $(PY_LINK) -Wall
CC = g++

test: minimal.o
    $(CC) $(CXXFLAGS) -o minimal.exe minimal.o

minimal: minimal.cpp
    $(CC) $(CXXFLAGS) -c minimal.cpp

然后运行make test给出：

minimal.o:minimal.cpp:(.text.startup+0x12): undefined reference to `__imp_PyTuple_New'
minimal.o:minimal.cpp:(.text.startup+0x1d): undefined reference to `__imp_PyLong_FromLong'
minimal.o:minimal.cpp:(.text.startup+0x2c): undefined reference to `__imp_PyTuple_SetItem'
minimal.o:minimal.cpp:(.text.startup+0x38): undefined reference to `__imp_PyFloat_FromDouble'
collect2.exe: error: ld returned 1 exit status
Makefile:29: recipe for target 'test' failed
make: *** [test] Error 1

我也检查libpython35.dll.a过nm，看起来功能在那里。例如，可以在 的输出中找到以下文本nm：

deuhs00780.o:
0000000000000000 b .bss
0000000000000000 d .data
0000000000000000 i .idata$4
0000000000000000 i .idata$5
0000000000000000 i .idata$6
0000000000000000 i .idata$7
0000000000000000 t .text
0000000000000000 I __imp_PyTuple_New
                 U _head_C__Users_ray_mc_x64_3_5_Library_home_ray_mc_x64_3_5_conda_bld_libpython_1476533413999__b_env_libs_libpython35_dll_a
0000000000000000 T PyTuple_New

那么问题出在哪里？谢谢。
