How to get GL4ES working on ALARM?

[blonxmaldo]

If i try to run anything on my Rpi4 with gl4es, I get this error: $this->bbcode_second_pass_code('', 'Failed to add service - already in use?')
I compiled it using "make -j4". In my config.txt file, I have "dtoverlay=vc4-fkms-v3d" and "gpu_mem=128".

I found this post on stack overflow that explained a lot: https://stackoverflow.com/questions/404 ... ady-in-use. It seems that it's trying to load a proprietary GL driver instead of mesa. I don't know why this happens, since mesa is installed. How can I just use gl4es and mesa?

There is already an issue on github about this, I just can't understand the solution: https://github.com/ptitSeb/gl4es/issues/134

I'm sorry if this is a dumb question, I'm a noob.
