I was trying to link an ATLAS implementation using -latlas instead of
-lblas in the makefile

it gets me the following error..

./mshadow/mshadow/tensor_expr_engine-inl.hpp:278: undefined reference to
`cblas_sgemm'

Google gave me the result
http://stackoverflow.com/questions/1137483/c-c-linking-error
Basically advised me to have extern "C" declaration..

When i see it in mshadow, it already has an extern "C" there.. Could
somebody help..

Thanks

Dear Chen,
thanks for the quick response.. i don't have a cuda GPU and was trying to use atlas since it has some parallel processing capability.. It looks like even lcblas do not have parallel computation..

You can use openblas
