I built the HoT dolphin emulator. It went through and gave me executables.
Then I changed the config to use GLES like this,

nano ~./config/dolphin-emu/GFX.ini
adding
PreferGLES = True


The gui of dolphin runs fine.
I didn't change any settings from default except to make sure 'OpenGL' was selected as graphics backend.
When I try to run a game I only get a black screen and immediate crash followed by this error message,

----------
Failed to compile vs shader: /home/fred/.local/share/dolphin-emu/Dump/bad_vs_OGL_0.txt
Debug info (Panfrost, Mali-G610 (Panfrost), OpenGL ES 3.1 Mesa 23.0.0-devel):
0:36(17): error: illegal use of reserved word `sampler2DMSArray'

---------


When I read the file /home/fred/.local/share/dolphin-emu/Dump/bad_vs_OGL_0.txt
I see that it starts by announcing its a #version 310 es  which it seems this environment and gl drivers should be able to support?

Does anyone know how to build Dolphin on an Orange Pi 5 with Linux?

Cheers and thanks for all your hard work!

I got a reply on Mesa gitlab,

"Hi, sampler2DMSArray requires 3.20 es. This is a bug in the emulator.
On page 17 of the GLSL ES 3.10 spec its listed under The following are the keywords reserved for future use. Using them will result in an error:"

This setup indicates that you have a modern ARM-based system with good graphics capabilities running a recent version of the Armbian operating system. You're using the Panfrost driver for your Mali-G610 GPU, which is an open-source driver that provides OpenGL support. This also works in the gaming world, for example I heard about Jackpot City Casino Canada from https://casinosanalyzer.ca/online-casinos/jackpotcitycasino.com it's a cool review. Additionally, you're using the Wayland display server as your desktop manager and compositor, which is known for its modern and efficient graphics handling. If you have any specific questions or need assistance with this setup, feel free to ask!

Don't miss a single moment of the action. With our https://stsprt.com/app/ live betting feature, you can place bets instantly as the game unfolds. Whether it's a last-minute goal, a crucial three-pointer, or a game-changing serve, you can bet on the outcome and add an extra level of excitement to your viewing experience.
