[ NVIDIA Grapics Card Error | MolCart 64 Bit | MolCart Install ]

Installation FAQ:

• I downloaded and installed ICM. It seems to start fine. However it dies every time I try to open something, giving an NVIDIA error. NVIDIA: Could not open the device file /dev/nvidiactl (Permission denied).
• I get chemlib.so erron:22 error when I install MolCart on 64Bit machines.
• I am having problems installing ICM on SGI.
• Where do I save my MolCart license?

23.1.1 I downloaded and installed ICM. It seems to start fine. However it dies every time I try to open something, giving an NVIDIA error. NVIDIA: Could not open the device file /dev/nvidiactl (Permission denied).

To permanently fix this problem you need to add the following line to /etc/logindevperm file

0 0666 /dev/nvidiactl:/dev/nvidia0:/dev/nvidia1:/dev/nvidia2:/dev/nvidia3

23.1.2 MolCart installation error on 64Bit machines

If you are installing MolCart and you come across this error:

Error> Can't open shared library 'chemlib.so' (errno: 22 chemlib.so: canno
t open shared object file: No such file or dire) (/usr/molcart-1.9-1/regmol
cart:52)
Error> error while running 'ExecSql(string("CREATE FUNCTION molcart_versi.
..))' (/usr/molcart-1.9-1/regmolcart:52)
Error> error while running 'regFunction(string("molcart_version"),string("
STRING"),)' (/usr/molcart-1.9-1/regmolcart:96)

Solution-- For 64 bit platforms molcart-1.9-1-linux64.sh should be used instead of molcart-1.9-1-linux.sh

23.1.3 Where do I save my MolCart license?

Save the MolCart license in:
