[RK3326/Mali] Assertion failure Shovel Knight

[Cebion]

Hi, I'm trying to run ShovelKnight on an RK3326 powered device Mali G31 GPU (ibmali-rk-bifrost-g31-rxp0) via GL4ES. I compiled GL4ES with -DODROID=ON -DGBM=ON -DNOX11=ON.

I run the game via BOX86_LIBGL=libGL.so.1 LIBGL_FB=4 LIBGL_ES=2 LIBGL_GL=21 LIBGL_DIBGL_FBOFORCETEX=1 box86 ShovelKnight

GL4es loads fine and I get the warning

Warning, function glXGetClientString not found in lib libGL.so.1 Warning, function glXGetClientString not found in lib libGL.so.1 Warning, function glXQueryVersion not found in lib libGL.so.1 Warning, function glXQueryVersion not found in lib libGL.so.1 librga:RGA_GET_VERSION:4.00,4.000000 ctx=0x633e6cd0,ctx->rgaFd=8 Rga built version:8827628f Using native(wrapped) libSDL2-2.0.so.0 ycMemory::Init() GL Version: 2.10 ycAssert! ../engine/src/ycRenderDeviceGL.cpp: 324 if(!(err == GLEW_OK)): Glew setup failed!

If I press Ignore the Game starts and runs perfect. Hope you have an Idea.

Thanks in advance

m trying to get box86 to run games on an RK3326 powered device using a Mali G31 GPU (ArkOS, libmali-rk-bifrost-g31-rxp0-wayland-gbm_1.7-2+deb10_armhf drivers from HardKernel), using Shovel Knight as a starting point.

It seems you built gl4es without X11 support, so a few fonctions (glXGetClientString and glXQueryVersion at least) are not found? I assume it does mess up libGLEW a bit?

[Cebion]

Yeah, I built it without x11 because we don't support x11. To test it I built it with x11 support but then gl4es doesnt get initialized at all and the log tells that

Using native(wrapped) libGL.so.1 Warning, function glXGetClientString not found in lib libGL.so.1 Warning, function glXGetClientString not found in lib libGL.so.1 Warning, function glGetString not found in lib libGL.so.1 Warning, function glGetString not found in lib libGL.so.1 Warning, function glXQueryVersion not found in lib libGL.so.1 Warning, function glXQueryVersion not found in lib libGL.so.1 librga:RGA_GET_VERSION:4.00,4.000000 ctx=0x633818d8,ctx->rgaFd=3 Rga built version:8827628f Using native(wrapped) libSDL2-2.0.so.0 Warning, function glClearDepth not found in lib libGL.so.1 Warning, function glClearDepth not found in lib libGL.so.1

[ptitSeb]

Ok. I'll see if I can add the 2 previous glX function to gl4es when built without X11 but with gbm

[ptitSeb]

So, I have pushed a commit on gl4es to add a few more glX function to a NOX11 build. Not sure if it will be enough.

[Cebion]

Thanks! I'll test this evening

[Cebion]

The GLX warning are gone =) Sadly the assertion warning still happens.

[ptitSeb]

Yeah, well, I'll need to check in libglew itself how the init is done, to see what's missing. not sure when I'll do that.

[Cebion]

No hurry, thanks for the effort!
