How come HAVE_MALLOC is not defined on your system?

from sdl.

Forgot to mention. I have those variables

        "SDL_STATIC": "ON",
        "SDL_SHARED": "OFF",
        "SDL_HIDAPI_LIBUSB": "OFF",
        "SDL_DUMMYVIDEO": "OFF",
        "SDL_HIDAPI_LIBUSB_SHARED": "OFF",
        "SDL_DIRECTX": "OFF",
        "SDL_VULKAN": "OFF",
        "SDL_HIDAPI": "OFF",

How come HAVE_MALLOC is not defined on your system?

I don't know. I recently fully reinstalled Windows 11. Installed Visual Studio Build Tools and used SDL3 for a month already until I've got this error.
CLang is from MSYS2 MINGW64. With this toolchain is working fine

While looking into RtlSetVolatileMemory, ReadPointerNoFence, ReadPointerNoFence, RtlFillVolatileMemory,
I found them in
D:\Windows Kits\10\Include\10.0.26100.0\um\winnt.h
And MapViewOfFile2 in
D:\Windows Kits\10\Include\10.0.26100.0\um\memoryapi.h
__imp_MapViewOfFileNuma2 - couldn't find at all

Found "malloc.h" in D:\Windows Kits\10\Include\10.0.26100.0\ucrt\malloc.h
#include <malloc.h> working fine. I don't know why CMake can't find it

from sdl.

Okay. Found what's happening then. It can find malloc.h. But it using another variable to check if it's enabled? Or I don't understand

from sdl.

Don't you need to use target_compile_definitions to define HAVE_MALLOC?

At the end of the configuration, a header is generated.
Something like include-config-debug/build_config/SDL_build_config.h.
If we would use compile definitions, the compile commands would become very long and unreadable.

from sdl.

SDL_build_config.h.intermediate has #define HAVE_MALLOC 1

Looking into other issue

from sdl.

Found it. Yeah. Thanks for the hints @madebr
I disabled "SDL_LIBC": "OFF" in a preset causing HAVE_LIBC to not be defined

I will now understand how to handle those problems properly. Sorry for panic)))

You can close it, if this issue not relevant and if SDL_LIBC need to be "ON" always
