Question

当我尝试使用此代码调用另一个类时，我得到的错误。这些函数在头文件中定义，头文件包含在类cpp文件和.h文件中。

check_decoder = new decoder_check();
check_decoder->run_CUDA( &g_bFrameStep, &g_bRunning, g_pFrameQueue, g_pVideoDecoder, g_pInteropFrame, g_pCudaModule, &g_bIsProgressive, g_DecodeFrameCount, g_pVideoSource, &g_bUpdateCSC, gfpNV12toARGB, g_KernelSID, g_CtxLock, g_oContext);
free(check_decoder);

错误是

链接错误...任何人都可以帮助我，包含头文件，库也是如此。谢谢。

从另一个类链接到另一个类时出错
