Hi all !

I'm trying to compile the 04_simpleTexturing example on a Raspberry Pi 4 on latest Bullseye

I'm using newer build and GLFW window

I'm having this error:
ofShader: sorry, it looks like you can't run 'ARB_shader_objects'

It seems that oF is using opengles. is this correct ?

This happens with using custom vertex and fragment shaders

Although running $ glxinfo says it is compatible with ARB_shader_objects

Here is the full output:

Hi @macramole,
Yes, OF should be using OpenGL ES.
Are you using the programmable renderer?
It looks like if it is not OpenGL ES, then ofShader will check if it's the programmable renderer, otherwise it will throw an error.

openFrameworks/libs/openFrameworks/gl/ofShader.cpp

Lines 661 to 676 in 7cf3cfe

void ofShader::checkAndCreateProgram() {
#ifndef TARGET_OPENGLES
if(GL_ARB_shader_objects) {
#else
if(ofIsGLProgrammableRenderer()){
#endif
if(program == 0) {
ofLogVerbose("ofShader") << "checkAndCreateProgram(): creating GLSL program";
program = glCreateProgram();
retainProgram(program);
}
} else {
ofLogError("ofShader") << "sorry, it looks like you can't run 'ARB_shader_objects'";
ofLogError("ofShader") << "please check the capabilites of your graphics card: http://www.ozone3d.net/gpu_caps_viewer";
}
}

Can you change this line in main.cpp:
OF_TARGET_OPENGLES

to

TARGET_OPENGLES

Oh I was losing my mind trying to figure out why it wasn't executing that chunk of code.

I'm having other issues though :

Nope, sorry. In 0.12.0 the error is:

I don't know much about shaders, but those lines look pretty standard to me. I tried some things like removing keywords like "in" "out" but I couldn't get it to work.

I also tried modifying Constants.h and was able to compile with glew (instead of using GL ES). Some things work but others crashed.

Hmmm. Can you post the output from the following?
if(ofIsGLProgrammableRenderer()){
shader.load("shadersGL3/shader");
cout << "-- Shader source --" << endl;
cout << shader.getShaderSource( GL_VERTEX_SHADER );
cout << "--------" << endl;
}else{
shader.load("shadersGL2/shader");
}

Thanks @NickHardeman , yes, tomorrow I will have access to the Raspi again and will post the output
