On configuring CUDA, cmake (2.8.7) on Win64/VS2010 bails out w/error:
CMake Error at C:/Apps/CMake/share/cmake-2.8/Modules/FindCUDA.cmake:877
Invalid format flag passed to CUDA_WRAP_SRCS: 'OBJ'. Use OBJ or PTX.
Call Stack (most recent call first):
Interestingly, the parameter delivered to the macro in L.877
is obviously 'OBJ', as can be seen here. Therefore, I made a
quick temporary hack and explicitely set
set( compile_to_ptx OFF )
in case of this error and turned the
error into a "notice". Diff is attached. I was not able
to deduce the real source of this error.
BTW, there seems to have been a tremendous effort in
enhancing Gromacs over the last months as can be
learned from the sources. Also the new tMPI imple-
mentation seems to be certainly faster when tested
against the 4.5.x internal-MPI on my 10^6 particle
Thanks & regards
