[Pw_forum] QE-GPU: compilation error with Espresso 5.1

After configure, what is the text after DFLAGS = inside make.sys?
I suspect two things:
- it looks like there are dirty object files around, please "make -f Makefile.gpu distclean" first
- by override FFT_LIBS, BLAS_LIBS and LAPACK_LIBS some of the internal checkings in the configure do not work properly
My strong suggestion is to edit make.sys after you run the configure, overriding FFT_LIBS, BLAS_LIBS and LAPACK_LIBS only if it is strictly necessary. In your particular case, by doing so you miss phiGEMM and MAGMA and other libraries to link to the final executable. I am improving over time the configure but it will take time to percolate these changes to the main distribution and into QE-GPU. I can add OpenBLAS support to the configure natively, it is not a process that take one day.
Speaking about CUDA 6.5, I has trouble running MAGMA with the latest CUDA toolkit recently. So my suggestion is to use a more stable CUDA 6.0 or temporary disable MAGMA. It is worh try but if the application has problems this is the first thing to remove.
