On Ubuntu 20.04 the AppImage fails with (iris is for Intel graphics):

Problem is caused by old libstdc++.so.6 contained in AppImage ... too old to be used by Mesa.

Issue could be solved by forcing system library:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./MachinekitClient_Development-201910151052-master-3863795-x64.AppImage

libstdc++.so.6 should be selected by AppImageKit-checkrt or removed.

On Fedora 32 it's the same. The current release requires the same fix, but the location of libstdc++ is slightly different.

LD_PRELOAD=/usr/lib64/libstdc++.so.6 ./MachinekitClient_Development-201910151052-master-3863795-x64.AppImage
