Compiling for RPi 2 [armv7l] Error: Could not find required OpenGL entry point 'glColorMaskIndexedEXT'! #392

Hi, I successfully built the project on "Raspberry Pi 2 Model B" but when i run the executable i get an error:

user@raspberrypi:~/build/hl2 $ ./hl2_launcher

Could not find required OpenGL entry point 'glColorMaskIndexedEXT'! Either your video card is unsupported, or your OpenGL driver needs to be updated.

it seems to be a common issue with an older GPUs... and people somehow get around it using this trick: https://github.com/ValveSoftware/Source-1-Games/issues/32#issuecomment-14117516 but its not applicable for ARM platform... is there is a way around?

What opengl versions your gpu supports? What driver do you use? Maybe try build gles3 engine? Anyway it should launch with gl4es, but performance will be awful..

pi@raspberrypi:~ $ glxinfo | grep "OpenGL"
OpenGL vendor string: Broadcom
OpenGL renderer string: VC4 V3D 2.1
OpenGL version string: 2.1 Mesa 20.3.5
OpenGL shading language version string: 1.20
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 20.3.5
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

It looks like rpi2 is using OpenGL v2.1, is this a problem?
