Ah yes, the compiling equivalent of "turning it off and on again."
Unfortunately it looks like the result is the same.
Double checking my CUDA_HOME, etc. settings:
>> nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2014 NVIDIA Corporation
Built on Thu_Jul_17_21:41:27_CDT_2014
Cuda compilation tools, release 6.5, V6.5.12
>> echo $CUDA_HOME
/usr/local/cuda-6.5
>> echo $LD_LIBRARY_PATH
/home/radak/software/amber14/lib:/usr/local/cuda-6.5/lib64:/usr/local/cuda-6.5/lib
The CUDA install instructions I found suggested the "lib64" addition above,
but the AMBER install msg only suggests "lib". Is that all cool?
