Matlab: libGL error: dlopen /usr/lib64/dri/swrast_dri.so failed
Starting Matlab R2015a or newer in CentOS7 or recent version of Fedora, the error libGL error: dlopen /usr/lib64/dri/swrast_dri.so failed will rise through does not affect the normal working of Matlab. This problem is caused by the libstdc++.so.6 coming with Matlab. Matlab carries statically linked libstdc++.so.6.0.17 in /matlab_folder/sys/os/glnxa64. When the system version of libstdc++.so.6 is lower […]
