I tried to compile gromacs-4.6beta1, is this the version you suggested? If not, please indicate how to download the source cause I am confused with all these development versions. Anyway, this is the error I get with 4.6beta1, gcc 4.7.2 and cuda 5: [ 0%] Building NVCC (Device) object src/gromacs/gmxlib/cuda_tools/CMakeFiles/cuda_tools.dir//./cuda_tools_generated_cudautils.cu.o /usr/lib/gcc/x86_64-redhat-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h(48): error: identifier "__atomic_fetch_add" is undefined /usr/lib/gcc/x86_64-redhat-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h(52): error: identifier "__atomic_fetch_add" is undefined 2 errors detected in the compilation of "/tmp/tmpxft_00002394_00000000-9_cudautils.compute_30.cpp1.ii".
