Dev: Building Troubleshooting

libGL error: failed to load driver: swrast

This is an error due to a missing driver that is required by newer versions of the libstdc++.so.6 file with version of gcc >= v11. If compiling the build on a distribution with an older version (e.x. Raspian Bullseye), either a newer version of gcc must be installed or the library must be included from elsewhere. The best fix I have found so far is to get the libstdc++.so.6 file from a distro that ships a newer version of gcc (i.e. Arch Linux ARM).

You may also need to recompile gcc from source. In that case, this guide looks like it does a pretty good job explaining the necessary steps, although it is not written for ARM. For that, this guide may provide some insight on the parameters necessary, although I have not tested it.
