Linking fails on 10.6: `Undefined symbols: _glGenVertexArrays, _glReleaseShaderCompiler, _glBindVertexArray` #570

Closed barracuda156 closed 1 month ago

These do not seem to exist on earlier macOS:

Undefined symbols:
  "_glGenVertexArrays", referenced from:
      _init_sdl_glsl_window in cava-sdl_glsl.o
  "_glReleaseShaderCompiler", referenced from:
      _init_sdl_glsl_window in cava-sdl_glsl.o
  "_glBindVertexArray", referenced from:
      _init_sdl_glsl_window in cava-sdl_glsl.o
ld: symbol(s) not found

Should we try using mesa or these symbols can be just enabled conditionally instead?

10.6? Snow leopard? 2009?

It is still used on earlier Intel (10.6 is the last macOS to run on CoreDuo machines) and PowerPC (ppc code was removed in 10.7).

Right, I forgot about the vintage computer enthusiasts. Some of those old macs were quite sturdy.

If you are not planning to use the opengl output you can disable it in the configure step with

--disable-output-sdl-glsl

@karlstav Thank you! Will try it and let you know.

@karlstav Yes, that worked :)
