LIBGL: warning, gles is NULL

[e-cl]

Good afternoon.

I'm trying to build and use gl4es in ubuntu running in chroot on android using linux deploy. I built gl4es but when i try to run something this is what happens.

I copied all libGLES*.so from my android. Or i did it wrong? Where do i get them them? Thank you in advance

I don't think the Android version will work. Is it the same architecture (like float-abi softfp vs hard). Use "file" on the Android lib to check, but I'm pretty sure you ened to find ubuntu version of the GLES libs for this to work.

I see. Thank you. Installed libgles2-mesa package, not it runs. Here's the output of glxinfo.

When i run glxgears, it does run, but frame rate is 20 fps, and when i maximize window, it drops down to 3. So aparently it runs in some kind of software rendering. Now my question is how to check this and get hardware rendering. I have 2 devices to test on: first is tablet with msm8226 snapdragon 400 with adreno 305, second is with MTK P25 with Mali T880. Which parameters shoud i use to compile gl4es and whick libgles libraries should i use, maybe it's mesa ones are software? Thank you.

[ptitSeb]

Yep, mesa will be software rendering only on you hardware. You need to find some mali (I guess?) GLES hardware driver for your hardware.
