Hi Wasim,
  I just made fresh VMD builds and an updated Linux binary
with the 256-bond-per-atom max bond count. The errors you encountered in the
previous build were completely unrelated to the max bond count change
and have been cured in the new test build. If you're using an older
NVIDIA driver (or no NVIDIA GPU) you'll still get that OptiX startup
error, but you can ignore that. I've posted the new 256-bond-per-atom
build for you here:
  http://www.ks.uiuc.edu/Research/vmd/alpha/256bonds/vmd-1.9.4a35.bin.LINUXAMD64.opengl.tar.gz

Please try it out and let me know if you still have difficulties.

Best,
  John Stone
