Stack overflow - segmentation fault with OpenGLES2 #267

Closed avafinger closed 2 years ago

avafinger commented 2 years ago

I get a segmentation fault while calling sandbox.setup(files, commands) with command line:

glslViewer _2D/00tests/test.frag

I am running with OpenGL ES2. Can you give some advice to debug this? Increasing the stack does not help.

HI do you mind sharing:

I can see glsViewer is linked with GL and not GLES, how can i enforce the use of GLES?

  • Did you compile the binary yourself? did you install one of the released binaries? what version?

I have compiled it from the source code (latest git). No pre-built released binary installed, only from source code.

  • What was the full command you run?

cd examples glslViewer 2D/00_tests/test.frag or with some printing info to see where it crashed ../build/glslViewer 2D/00_tests/test.frag

So, can you instruct how to build it with full debug info? Looks like some variables might have not been initialized during the compileShader(). Are there any restrictions to running with OpenGL ES2 ?

I was wondering if is not possible for you to update to the latest glfw, i have the latest glfw (git) running in my setup but you use some previous versions during build and link. I don't think this is the problem.

avafinger commented 2 years ago

Just an update. The rendering part is to be done with OpenGLES2, and that seems to be working.

Question, are you running glslViewer from a X11 enviroment? or directly from the terminal? Seams you compiled the GLFW which only works inside X11 environment. It should take care of compiling against OpenGL ES 2. But in the case of you wanting to specify it here you can change it https://github.com/patriciogonzalezvivo/ada/blob/e83950d91d8fee930655090406e73cb902581659/src/CMakeLists.txt#L230-L237

Question, are you running glslViewer from a X11 enviroment?

yes, X11. glfw only works with X11 (and OpenGLES2). I will try to understand what you proposed and enforce GLES.

patriciogonzalezvivo commented 2 years ago

There is a #define flag call PLATFORM_RPI added when you are compiling on a Raspberry Pi, which skip some of the more advance GPU features and replace them with some that this limited GPU have ( related to missing extensions ). Maybe you can try replacing this https://github.com/patriciogonzalezvivo/ada/blob/main/src/CMakeLists.txt#L231b for this one https://github.com/patriciogonzalezvivo/ada/blob/main/src/CMakeLists.txt#L67

I got it working. There seem to be some issues with rendering, i believe. But i have to learn more about your nice tool.

I will try to join your channel and learn more about how to use it. The fix was to force the linking with GLES2v2 and EGL (from rockchip).

Thank you for your work and for the advice.
