Do you mean you have disabled FKMS on the Pi4? If so, you have no 3D support/driver, so gl calls will not work correctly.
On the Pi3 you could use the older userland code talking to the VC4 3D HW, the FKMS driver is disabled by default,
Actually I'm using a Raspberry Pi 3 and is working on Yocto images, not Raspbian. When I turn on the fkms the glGetString error doesn't occur, but when it's disable, I am having the glGetString error.
I'm trying a Yocto build for RPi, when I disable vc4, and try to run an openGL application, I get an error saying it can't resolve glGetString(GL_VERSION). When I looked for the cause of that error, it said I doesn't have a proper openGL implementation. Any ideas on how I can get past it? (Enabling vc4 is not an option for me)(I'm posting this here cos RPi uses userland display libraries when vc4 is disabled)
