阿新 • • 發佈:2021-07-16
匯出ffplay動態庫,發現m_FunMain_abc = (fmain_abc)GetProcAddress(m_hDllPlay, "main_abc"); 一直是0,
#ifdef CSPPRODUCTIONTOOL_EXPORTS #define CSPPRODUCTIONTOOL_API __declspec(dllexport) #else #define CSPPRODUCTIONTOOL_API __declspec(dllimport) #endif CSPPRODUCTIONTOOL_API int main_abc(void* hwnd);
後來用下面網址的命令DUMPBIN /EXPORTS dll_file_name.dll,

改成
extern "C"{
CSPPRODUCTIONTOOL_API int main_abc(void* hwnd);
}
後ok了
