That's strange:

https://github.com/hrydgard/ppsspp/blob/c9c060fcdbd222f7c64fd47a3f70a54fefa3a874/Core/Dialog/SavedataParam.cpp#L30 https://github.com/hrydgard/ppsspp/blob/fe1807b2ecc2558ea951e81396a7e9e19d23d299/Core/HLE/sceKernelMemory.h#L61

sceKernelGetCompiledSdkVersion() should be perfectly well defined in scope. It's not using any floats so it ought not be affected by hard float or otherwise. Does git status show no differences?

On aarch64 i solved by

On armhf it was just

the armhf build is using LIBGL by default and segfaulting with

Maybe i can force an opengl-es build, ignoring ptitseb's gl4es libraries?

[unknownbrackets]

Do you have both USING_EGL and USING_GLES2? What was your full cmake command?

-[Unknown]

[clort81]

managed to force the glesv2 by moving-out my libGL.so

USING_EGL and USING_GLES2 are both ON

cmake was cmake /big/src/ppsspp

Running gets me.

screen resolution is 960x540, not 544, so maybe i could set things to single scaled 480x272 ? My

[unknownbrackets]

Has this gotten any better with updated drivers?

-[Unknown]

[clort81]

Sorry for lack of reply unknownbrackets: better drivers not forthcoming. We have no active driver development. Amazingly i did get a build that runs - sometimes. My brain has turned to mush though - I should have really gotten a d-dimer clotting test.

video proof! playable fps (for rpg)!!

I'll try to figure it out - maybe this patch will help. force sdl2 to use gles Perhaps someone with another omap4 device could give it a shot? Cheers!

1. The screen has 960x540 so idk why it's asking for 960x544 despite FullScreen = True in ppsspp.ini. Maybe i can address that first?
2. E[LOADER] fails opening OPENGL, ALL - but i specified opengl-es. Is this just a misleading error message?

[EDIT] Forcing pixel_xres and pixel_yres to 960x540 results in Pixels: 960 x 540, Virtual pixels: 960 x 544 and same

I seem to recall getting this intermittently in previous OS revisions, now it's consistent. The backtrace shows

3639    malloc.c: No such file or directory.

At this point, would i want to see what parameters libxcb is being invoked with? Corrupt stack prevents introspection with gdb?

[EDIT2] This doesn't look right: 30:32:549 Core/Config.cpp:615 I[G3D]: Longest display side: -1 pixels. Choosing scale 1 This gets set in Config.cpp

        int longestDisplaySide = std::max(System_GetPropertyInt(SYSPROP_DISPLAY_XRES), System_GetPropertyInt(SYSPROP_DISPLAY_YRES));
        int scale = longestDisplaySide >= 1000 ? 2 : 1; 

I'll try force setting SYSPROP_DISPLAY_XRES and YRES now. As an aside.. Seems to me that a Display of 960 would be enough for scale=2

[EDIT3] Forcing int longestDisplaySide = std::max(960, 540); still results in malloc(): smallbin double linked list corrupted

After installing gnulib (containing maloc.c) gdb backtrace shows more output:
