Hi Amber users,
Recently we have acquired a K20 NVIDIA GPU to use it with Amber12.
We have Ubuntu12.04 istalled in our machine. After installing the hardware
we compiled the CUDA5.5 there. Then we set the CUDA_HOME path in our
.bashrc file.
Then we extracted the Amber12 and AmberTools using following commands:
*tar jxvf Amber12.tar.bz2tar jxvf AmberTools13.tar.bz2*
after changing the directory to amber12 we ran the following command:
*./configure -cuda gnu*
All the patches were accepted and configured.
Then we executed this command:
*make install*
After some time this exited with the following errors:
*make[4]: Leaving directory

It would be very help if anyone can point out what is problem and how
should I rectify this issue.
