Hi, I have following error when trying to run Chimera remotely on CentOS7 system from OSX this seems to affect also Windows with Xming libGL error: dlopen /usr/lib64/dri/swrast_dri.so failed (/opt/sci/UCSF-Chimera64-1.10.1/lib/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib64/dri/swrast_dri.so)) libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast X Error of failed request: GLXBadContextTag Major opcode of failed request: 150 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 1359 Current serial number in output stream: 1359 On windows the error is: ibGL error: dlopen /usr/lib64/dri/swrast_dri.so failed (/opt/sci/UCSF-Chimera64-1.10.1/lib/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib64/dri/swrast_dri.so)) libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast X Error of failed request: GLXBadCurrentWindow Major opcode of failed request: 145 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 1350 Current serial number in output stream: 1350 How I can get this to work? Intended use would be in classroom where we don't have permissions to run or install Chimera.
