search for: __nv_mul24

Hi, I was trying to compile scalarProd.cu (from CUDA SDK) with the following command: * clang++ -I../ -I/usr/local/cuda-7.0/samples/common/inc --cuda-gpu-arch=sm_50 scalarProd.cu* but ended up with the following error: *ptxas fatal : Unresolved extern function '__nv_mul24'* Seems to me that libdevice was not automatically linked. I wonder what flags I need to pass to clang to have the code linked against libdevice? Thanks! Yuanfeng Peng -------------- next part -------------- An HTML attachment was scrubbed...
