[Chimera-users] How to correct this error: ~/usr/chimera-1.12/lib/libgomp.so.1: version `GOMP_4.0' not found (required by /usr/lib/libopenbabel.so.4)

[Francois Berenger]

Hello,

On a Ubuntu 18.04.1 LTS, I get this error message when I start chimera.

Is there a known fix?

Am I running a too old version of chimera or should I run
a version specially compiled for Ubuntu computers?

Here is the full error message:
