The error involves pbsa.cuda, which may not be the program you really
want (most people are more eager to run pmemd.cuda). If that is the
case, after the configure step, do this:
cd src/pmemd
make install
That will install just pmemd.cuda, whose installation is better tested.
(Of course, you may still have problems, since for most people, building
pbsa.cuda gives no problems. If things still don't work, provide some
details about your OS, compiler and CUDA toolkit versions. Also, since
you apparently previously installed the cuda.MPI versions, and are now
trying to get the cuda serial codes, start from a completely fresh
directory tree, just in case something left over from the MPI install
is causing problems.)
I'm cc-ing this to Ray Luo, in case he may have a better handle on
recognizing the problem.
...good luck...dac
