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

我试图设置一个工作流程，用于在Windows 7 64位上使用Cython和MinGW从Python 3.5.1代码生成.pyd和.exe文件。在Windows 7（64位）上使用Cython和MinGW编译Python 3.5代码

我有一个简单example.py文件：SO

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

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

从其他线程，我得到下面用Cython命令，该命令生成.c文件的w/o警告。

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

当我调用gcc时，我得到以下警告，并不太清楚这些是否为关键。

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来生成.pyd文件，我得到了一堆不确定的参考信息和LD退出与一个错误状态。

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

我在做什么错？

我必须改变我的工作流程才能生成独立的.exe文件？

尝试加入'-shared轮候册， - 启用 - 自动图像基地轮候册， - 启用 - 自动import'到链接命令 –

这不会改变任何东西。 – Juergen

都是gcc和python 64bit版本？ –

在J.J.的帮助下，Hakala，我发现下面的命令来产生所需的输出文件：

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

PYD 64位

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

EXE 64位

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为您提供支持。

我设法建立用gcc 5.3.0（64位，SEH）

第一步蟒3.4（64位）基于用Cython模块，

移动python3.lib和python34的.lib从远C：\ Python34 \库（例如一个子目录那里）
复制从çpython34.dll：\ Windows \ System32至c：\ Python34 \ libs使用Windows资源管理器（必须使用64位应用程序）。

使用时用Cython与--embed

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

当创建一个模块，

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

GCC似乎处理DLL比LIB文件链接时更好文件。

我能够编译一个简单的测试，但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）。然而，使用上面提到的命令生成一个.exe文件给了我'gcc：error：无法识别的命令行选项'-municode' – Juergen

@Juergen可以使用-mconsole（或不使用）吗？ –
