在Windows 7（64位）上使用Cython和MinGW编译Python 3.5代码

我正在尝试设置一个工作流，以便在64位Windows 7上使用Cython和MinGW从Python 3.5.1代码生成.pyd和.exe文件

我有一个简单的example.py文件：

def hello(x):
    print("Hello",x)

if __name__=='__main__':
    hello("World!")

从其他线程中，我得到了下面的Cython命令，该命令生成了一个不包含警告的.c文件

cython --embed -o example.c example.py

当我调用gcc时，我得到以下警告，不知道这些警告是否是关键的

gcc -c -IC:\Python35\include -o example.o example.c

In file included from C:\Python35\include/Python.h:65:0,
                 from example.c:4:
C:\Python35\include/pytime.h:113:5: warning: 'struct timeval' declared inside pa
rameter list [enabled by default]
     _PyTime_round_t round);
     ^
C:\Python35\include/pytime.h:113:5: warning: its scope is only this definition o
r declaration, which is probably not what you want [enabled by default]
C:\Python35\include/pytime.h:118:5: warning: 'struct timeval' declared inside pa
rameter list [enabled by default]
     _PyTime_round_t round);

当我使用gcc生成.pyd文件时，我得到一堆未定义的引用消息，ld退出时状态为错误

gcc -shared -LC:\Python35\libs -o example.pyd example.o -lpython35

我做错了什么

---

为了生成一个独立的.exe文件，我必须更改我的工作流程吗？

我设法用gcc 5.3.0（64位，seh）为python 3.4（64位）构建了一个基于Cython的模块

第一步

将python3.lib和python34.lib从c:\python34\libs中移出（例如，其中的子目录）

使用Windows资源管理器将python34.dll从C:\Windows\System32复制到C:\python34\libs（必须使用64位应用程序）

将cython与--嵌入一起使用时

cython --embed test.py
g++ -municode -mthreads -Wall -O -I/c/Python34/include -L/c/Python34/libs test.c -lpython34 -o test.exe

创建模块时

cython test.py
gcc -mdll -O -Wall -I/c/Python34/include -c test.c
gcc -shared -L/c/Python34/libs test.o -lpython34 -o test.pyd

---

在链接时，gcc似乎比lib文件更好地处理dll文件。

在J.J.Hakala的帮助下，我找到了以下命令来生成所需的输出文件：

pyd 32位

cython -o example.c example.py
gcc -c -Ofast -IC:\Python35-32\include -o example.o example.c
gcc -shared -LC:\Python35-32\libs -o example.pyd example.o -lpython35

cython -o example.c example.py
gcc -c -DMS_WIN64 -Ofast -IC:\Python35\include -o example.o example.c
gcc -shared -LC:\Python35\libs -o example.pyd example.o -lpython35

cython --embed -o example.c example.py
gcc -municode -DMS_WIN64 -mthreads -Wall -O -IC:\Python35\include -LC:\Python35\libs example.c -lpython35 -o example.exe

pyd 64位

cython -o example.c example.py
gcc -c -Ofast -IC:\Python35-32\include -o example.o example.c
gcc -shared -LC:\Python35-32\libs -o example.pyd example.o -lpython35

cython -o example.c example.py
gcc -c -DMS_WIN64 -Ofast -IC:\Python35\include -o example.o example.c
gcc -shared -LC:\Python35\libs -o example.pyd example.o -lpython35

cython --embed -o example.c example.py
gcc -municode -DMS_WIN64 -mthreads -Wall -O -IC:\Python35\include -LC:\Python35\libs example.c -lpython35 -o example.exe

exe 64位

cython -o example.c example.py
gcc -c -Ofast -IC:\Python35-32\include -o example.o example.c
gcc -shared -LC:\Python35-32\libs -o example.pyd example.o -lpython35

cython -o example.c example.py
gcc -c -DMS_WIN64 -Ofast -IC:\Python35\include -o example.o example.c
gcc -shared -LC:\Python35\libs -o example.pyd example.o -lpython35

cython --embed -o example.c example.py
gcc -municode -DMS_WIN64 -mthreads -Wall -O -IC:\Python35\include -LC:\Python35\libs example.c -lpython35 -o example.exe

---

非常感谢J.J.Hakala的支持。

尝试将

-shared-Wl，--enable auto image base-Wl，--enable auto import

添加到链接命令这不会改变任何东西。gcc和python都是64位版本吗？python肯定是64位的，但我不确定gcc。gcc——版本为4.8.1，来自MinGW安装管理器，我想它相当于32位。从哪里可以获得64位版本的MinGW？或者我应该切换到Python 32位吗？我会使用msys2。然后，您可以选择安装gcc（64位，但链接到libmsys）和mingw32&mingw64。我在完全相同的问题atm机，并已恢复到32位py34。这篇文章应该允许我转到64位py34。但是现在mingw由于一个变化而不能容忍py35扩展。我能够编译一个简单的测试，但是测试可执行文件或模块会导致崩溃。我切换到32位Python，并设法生成并启动一个example.pyd文件（没有崩溃）。但是，使用上述命令生成.exe文件会给我

gcc:error:无法识别的命令行选项'-municode'

w/o-municode，我得到

未定义的引用'WinMain@16“

。使用gcc 5.3.0（64位），我能够生成pyd和exe文件，但都会崩溃。@Juergen我添加了flag

-DMS\u WIN64

，现在我似乎能够为64位python 3.5构建基于cython的exe/模块
