So I have a VS2010 project file but am using identical source codes files (.h, .cpp, .cu, .cuh. VS2010 build compiles everything fine, but linking reports error with unresolved external: Generating Code... 1>videoFuncUnThread.obj : error LNK2019: unresolved external symbol _runKernel referenced in function "void __cdecl videoFuncUnThread(int,bool,unsigned int * const)" (?videoFuncUnThread@@YAXH_NQAI@Z) 1>D:\StrApp\Viper1B_10\Viper1B_10\Debug\Viper1B_10.exe error lnk2019 unresolved external symbol visual studio 2010 : fatal error LNK1120: 1 unresolved externals 1> 1>Build FAILED. 1> the missing symbol, runKernel, is host-side module that calls device side modules (resident in PTX file). when I search for all occurances of runKernel, I get 3 lines: filter.cu(127): extern "C" CUresult runKernel (int numFrames, cudaStream_t stream, bool firstBatch, int* searchLimit) { ... } // module code videofuncunthread.cpp(28): extern "C" CUresult runKernel(int numFrames, cudaStream_t stream, bool firstBatch, int* search); // videofuncunthread.cpp(137): CUresult resultKernel = runKernel( NinBatch, gStream, firstBatch, (int *)searchLimit); since "filter.cu" compiles it means that the invocation line (137) agrees with the prototype declaration (28); also you can see that the definition in filter.cu is identical with the prototype. Finally I note that I have successfully compiled, linked and run examples from the cuda 5.0 samples on VS2010. i have verified that i am using the same Cuda build rules in both projects and that the project properties between my project and the Cuda sample project are the same. any insight or suggestion you can offer would be greatly appreciated. thanks cuda gpu share|improve this question asked Jan 14 '13 at 23:08 JPM 1101112 went back and set warnings to level 3 in case i was missing some warning. no change, no warnings. –JPM Jan 14 '13 at 23:11 1 int *search (being re
