GPUMLib unresolved externals at build time

Question

I am trying to build GPUMLib, and I get the following errors

Error   11  error LNK2019: unresolved external symbol "public: static void __cdecl         GPUMLib::Random::SetSeed(unsigned __int64,enum curandRngType)" (?SetSeed@Random@GPUMLib@@SAX_KW4curandRngType@@@Z) referenced in function _main  C:\libraries\GPUMLib1\build\src\examples\DBN\DBNapp.obj

Error   12  error LNK2019: unresolved external symbol "public: static void __cdecl GPUMLib::Random::Fill(class GPUMLib::DeviceArray<float> &)" (?Fill@Random@GPUMLib@@SAXAAV?$DeviceArray@M@2@@Z) referenced in function "public: void __thiscall GPUMLib::RBM::ContrastiveDivergence(int)" (?ContrastiveDivergence@RBM@GPUMLib@@QAEXH@Z)   C:\libraries\GPUMLib1\build\src\examples\DBN\RBMKernels.lib(RBMKernels_generated_rbm.cu.obj)
Error   13  error LNK1120: 2 unresolved externals   C:\libraries\GPUMLib1\build\src\examples\DBN\Debug\DBN.exe  1

Any ideas what might be causing this ? Please note that this is the only part that is unsuccessfully built from the entire library

Answer 1

As the authors of the library suggested, in the src/random folder I had to rename "random.cu" to "random.cpp". This solved the problem.
