No libGLESv1_CM.so symlink present

[a1batross]

libGLESv1_CM.so is a common name for any GLESv1 implementation library.

I see, that libGL.so implements GLESv1, but software mostly don't consider about this library naming. For example, SDL2 tries to find GLESv1 implementation in libGLESv1_CM.so and it just shows me a error like: "Could not initialize OpenGL / GLES library".

SDL2 isn't the only, there is many other possible code, which doesn't know that libGL.so.1 implements GLES interface.

Meanwhile, libGLESv1_CM.so present only in nvidia-* driver package.

[Timo Aaltonen (tjaalton)]

GLESv1 support was dropped quite some time ago.

[a1batross (a1ba-omarov)]

Thanks for the answer!

When and why it was dropped, while drivers still have GLES1 calls inside binary? Mesa's libGL.so still does have them.

Proprietary drivers also don't drop GLES1 support, GLES1 functionality persists in latest NVidia driver.
