SOKOL_MALLOC/CALLOC/FREE macros are no longer supported

[MattiaBettini]

I'm working on a visual studio project using sokol_gfx and sokol_gp.

I am using sokol_gfx master branch after allocator-interface merge.

The first error I had was: "'SOKOL_MALLOC': identifier not found" from sokol_gp, after doing an extended search I found this error in conditional compilation at line 2625 of sokol_gfx.h: "SOKOL_MALLOC / CALLOC / FREE macros are no longer supported, please use sg_desc.allocator to override memory allocation functions ".

Is there a fix for this problem? or am I doing something wrong?

Same here. My quick workaround until it gets fixed:

#define SOKOL_MALLOC _simgui_malloc
#define SOKOL_FREE _simgui_free
#include "sokol_gp/sokol_gp.h"
#undef SOKOL_MALLOC
#undef SOKOL_FREE

bumping as I'm running into this as well when trying to build this into a dll with sokol

Actually trying to do all this now, taking on the imgui dep just to resolve the malloc is proving to be a giant PITA (cimgui.h having issues compiling on M1) — @edubart I'm still mostly a C noob but if you have any tips to resolve this directly in sokol_gp instead of routing through imgui that would be great! happy to try and tackle it and submit a pr if it seems like an easy fix.

[edubart]

I've updated the library to use latest sokol allocator system, it should fix this.

Thanks so much @edubart ! Trying now.
