This question is not about GROMACS development, and would be more suited 
for the users mailing list. Please direct all similar questions there 
instead in the future.

However, as the message says, GPU acceleration cannot be combined with 
double precision. Decide if you want -DGMX_GPU=on or -DGMX_DOUBLE=on. In 
most cases you don't need double precision.
