for building miRack on ubuntu 18.04 arm (32bit) i had to add the "-mfpu=neon" option to the CFLAGS - looks like this is not set by default on ubuntu. running miRack without hardware gpu acceleration works with "export EGL_PLATFORM=x11", but this eats a lot of cpu for the software rendering of the EGL stuff and is only partially useable, if the framerate is turned down further (i set it to 5) in src/windows.cpp or the miRack window is iconified.
