首先,感谢大家过去几年在这个论坛上给我的所有答案,但是今天我找不到明确的答案,所以我觉得是时候发帖了。
我设法test5.cpp
在我的 Debian 发行版上编译和运行 C++ 代码,将它(也许它不是正确的词)包装到一个Amod.py
带有 SWIG 的 python 模块中(这需要一个“翻译”文件test5.i
。我使用并成功导入了模块用于数据分析到其他更复杂的 python 代码(基本上是对 numpy 数组、matplotlib 等的操作..)。
现在我想在 Windows 计算机上运行相同的代码,但是 python 不能再导入模块,库文件_Amod.so
是 .so 文件,而不是 Windows 期望的 .pyd。但是我找不到在 Windows 上重新编译它的快速简便的方法。我挖掘 CodeBlocks 文档,但它的漏洞,我迷路了。( http://wiki.codeblocks.org/index.php?title=Adding_support_for_non_C/C%2B%2B_files_to_the_build_system )
基本上我想运行下面的工作代码的 Windows 等效项(我希望可以帮助初学者是 SWIG):
编译:
swig -c++ -python test5.i
g++ -fPIC -c test5.cpp
g++ -fPIC -c test5_wrap.cxx -I/usr/include/python2.7
g++ -shared test5.o test5_wrap.o -o _Amod.so
我应该使用哪种软件和编译器,以及如何在不浪费时间的情况下使用?(我已经有了 CodeBlocks)非常感谢。
如果需要,请test5.i
参阅以下内容,将 C++ 数组包装在 numpy 数组中,添加一些内联(替换函数)以用于检查目的(所有内容都被挖掘到血腥的痛饮帮助中):
