>>> print f < SWIG Object of type 'FILE *' at 0xb7d6f470> This pointer value can be freely passed around to different C functions that expect to receive an object of type FILE *. The only thing you can't do is dereference the pointer from Python. Of course, that isn't much of...

使用swig - version 确认版本型号即为安装完成。 swig: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory 问题主要是swig使用时,找不到libpcre.so.1文件,我们在系统中查找以下它的位置: sudo find / -name libpcre.so.1 查询后发现这个文件...

void printme(DateTime dt); 到目前为止,我能够创建这个SWIG类型映射,将其从datetime转换为DateTime %typemap(in) DateTime { PyObject* str = PyString_FromString( "timestamp" ); PyObject* obj = PyObject_CallMethodObjArgs( $input, str, nullptr ); ...

如果你也像我们一样,同时使用Python和C++,以获得两种语言的优势,一定也会希望寻找一种好的方式集成这两种语言,相比而言,让Python能够方便使用C++的库更...
