Indeed, adding the flag -lrt to the general definition of the cuda_libs
in the configure file solves this issue and the cvs code compiles ...
However, I find that the new VMD starts significantly slower than the
1.9.2 version compiled exactly on the same machine with exactly the same
Anybody else experiencing this ?
