Hello, I'm preparing a change to the Chimera installer that will workaround this problem. In the interim, you can remove the following libraries from CHIMERA/lib, where CHIMERA is the root of the Chimera installation tree:

libgcc_s.so.1, libstdc++.so.6, libgfortran.so.3, libgomp.so.1, and libXss.so.1

That assumes that your system has those libraries installed elsewhere and that they are more recent than what comes with Chimera. The libraries are the C runtime library, the C++ runtime library, the Fortran runtime libraries, and the X11 screensaver extension library. I noticed in your error report that your system is using a software OpenGL renderer, Mesa. If you have AMD or NVIDIA graphics, please install the proprietary driver from the vendor, www.amd.com or www.nvidia.com, respectively. The proprietary drivers have much better performance and are more efficient than the open-source drivers. If you have Intel graphics, then your only choice is the open-source driver, so in that case I'd recommend switching to a Linux distribution that keeps up with changes in the graphics drivers, like Ubuntu. The Intel drivers are way better than they used to be, but are still undergoing a lot of development. FYI, CentOS 7 comes with Mesa 9.2 and Ubuntu 15.04 has Mesa 10.5, need I say more?

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.
