Issue with shader

[pbaret]

Hey, I just found your video series and the source code for the RPG, I manage to build it and found a lot of interesting stuff so first of all thank you! However I have a problem when I click "New Game", it crashes with a shader error in the console:

Failed to compile vertex shader:
WARNING: 0:1: '' :  #version directive missing
WARNING: 0:1: 'varying out' : symbol not available in current GLSL version
ERROR: 0:1: 'varying out' :  supported in fragment shaders only

ERROR::GAMESTATE::COULD NOT LOAD SHADER.

Any idea what is the problem? and maybe a hint on how to fix or work around this?

I know C++ very well, just started SFML (built 2.5.1 from source on Windows with MinGW 12.2.0, I do have a NVidia GPU on the machine) but I have very limited knowledge on shaders.

When you create the RenderWindow, are you setting the gl version? Are you also specifying the version with the #version directive? I had the same issue awhile back. Apparently, large portions of the SFML graphics module are written using depreciated parts of the OpenGL library and won't have foward compatibility. I fixed the issue by simply removing the depreciated part, "varying". Hope you find a solution soon! :)

No I didn't make any modifications of the original code when experiencing the crash. I was just using my own toolchain to build the project : SFML and Compiler I have on my PC and CMAKE :

• mingw 12.2.0
• SFML version 2.5.1 built from source

I had to build a CMakeLists.txt though :
