Below is the info I have on the CUDA and gcc versions. After typing in gcc --version, as you mentioned ,it lists the gcc version as 5.3.1 and when I went to the
/usr/local/cuda directory and looked at the version.txt file it shows the CUDA version as 7.5.18. However, when I type in nvcc --version, as shown below, it states that bash: nvcc: command not found...
Also, I am not sure what you meant by "You can generally see if /usr/local/cuda is a symlink to someplace else."
I suspect that means if I type in "cd /usr/local/cuda" it would go to a different directory, so i did so and when I typed in cd /usr/local/cuda it sent me to the cuda directory.
I apologize for my ignorance, but how do I correct the issues of having the "wrong" versions of gcc and possibly CUDA?
As a reminder the error I received when trying to install the CUDA for GPU-accelerated versions of pmemd for AMBER 18 was #error -- unsupported GNU version! gcc versions later than 4.9 are not supported!
[AmberPc.cs-127a-26042 cuda]$ nvcc --version
bash: nvcc: command not found...
[AmberPc.cs-127a-26042 amber18]$ gcc --version

It's better to use "gcc --version", since the gcc in your PATH might be
have changed from the one originally installed with the OS.

What version of the cuda SDK do you have? You can generally see if
/usr/local/cuda is a symlink to someplace else. Or, type 'nvcc
--version'
