Check if extension supported at compiletime?

[noxomix]

Hello, Im currently creating OpenGL Bindings for the V programming language. Just there is one problem, I cannot conditionaly bind if a C-function is available or not.

Which basically means, I need to define a functio rather if its available or not. So I will also bind a openGL extension function if the extension is not avaialble on the current system. Just that instead the actaull GL call, it just do a printf("This is not supportet...")

My first idea was, according to one of the Github issues here, i can determine on Runtime if a extension is available by using the GLAD_{fn_name}-syntax. which means i could define a C function and do if extension_available return glMyCoolFunctionAMD else printf("AMD is not available on Intel Hardware") , now the Question is, how exactly can I do this at Compile time? So is there a #if GL_extension_available #else ... way to do wat i want, without chaging the glad generated file ?

Im unfortunatly not very experienced in C yet, so thats why im asking.

Best Regards
Theo

Okay I found out the solution,, just use #ifdef and #define, thank you anyways.
