Hello,
I opened the Visual Studio 2008 project of the SDK “matrixMul” and I didn’t get any issue to compile it with the default options (I’m using CUDA 4.0 under windows 7 64 bits). But if I change the runTime library flag from “/MT” to “/MD” (project’s properties → C/C++ → Code Generation → Runtime Library), I got the following errors:
Error 1 error LNK2005: "private: __cdecl type_info::type_info(class type_info const &)" (??0type_info@@AEAA@AEBV0@@Z) already defined in LIBCMTD.lib(typinfo.obj) MSVCRTD.lib
Error 2 error LNK2005: "private: class type_info & __cdecl type_info::operator=(class type_info const &)" (??4type_info@@AEAAAEAV0@AEBV0@@Z) already defined in LIBCMTD.lib(typinfo.obj) MSVCRTD.lib
Error 4 fatal error LNK1169: one or more multiply defined symbols found c:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\bin\win64\Debug\matrixMul.exe
It looks similar to this other topic including Thrust: http://forums.nvidia.com/index.php?showtopic=195470. But at the end of the topic they say that the issue was fixed in CUDA 4.0 (final). So I guess my question is why it’s not possible to compile an SDK example with /MD ? Is it a desired behaviour or is there a bug in nvcc? Since we use the flag /MD in a big project I’m wondering if I will be able to use CUDA 4.0 within this project.
