Build flow and compiling: Improving compilation by utilizing mingw/make – can't find SDL about supermodel HOT 15 OPEN

Good, that gives us a more informed starting point - cheers.

I already have the supporting libraries installed with mingw, including SDL. It even starts compiling.
The problem I am running into is getting GCC to include SDL. No matter what I set for
SDL_INCLUDE_DIR and SDL_LIB_DIR in https://github.com/trzy/Supermodel/blob/master/Makefiles/Makefile.Win32#L52,L53
It fails to find SDL.h.
It throws this error everytime:

Yet I know gcc can find the includes, it looks in them earlier:

SDL's include folder is properly populated:

And SDL files are present under libs:

It's possible to have supermodel be automatically built, I just need to figure out what the makefile wants. In the meantime, I'll see if I can get linux and MacOS builds going.

Found the issue. For some reason
https://github.com/trzy/Supermodel/blob/master/Makefiles/Makefile.Win32#L96 $(addprefix -I,$(sort $(PLATFORM_INCLUDE_DIR)))
Wasn't adding the paths to the compiler. I have them hard coded (for now) and now it has an issue with linking, but I think I can fix it. Will update later.

Running into issue with unicode and minGW's lack of some kind of support.
This https://stackoverflow.com/questions/58324230/undefined-reference-to-winmain-c-mingw says you only need to add -municode to the compiler options, but in doing so it now produces different errors about converting char* to LPCWSTR:

I'll keep going at it.

FWIW, I tried this a while ago and also found the GitHub VM file paths way too funky. There, but not there???
Edit.
Just need to change makefiles if using brew install. No big deal after all.

More news.
It took me some time before I finally remembered paths were case sensitive on *nix, but when I did Supermodel pretty much built without any problems. It throws some errors about format overflows, but still compiles and links. I'll take that as a win.
MacOS is a different story, without -Wno-error=implicit-function-declaration it fails in m68kcpu and m86kopnz.

With it, it fails in linking; complaining about not finding SDL, but that doesn't really make sense when it was able to find SDL.h...

Also thanks @ToBul, I've never used C, I would have never figured out the header stuff.

I had another go at this.
What looks like overflow errors is when you build with netboard but forget to amend SDL net #includes.
Once you do that it builds Win and Ubuntu cleanly and you can leave the Warning settings alone.
Hopefully this will go some way to helping OSX build too. ??

Hey @ToBul, give yourself some credit.

I only know a bit about making manifests and barely see any logic in programming – that's why I wanted to put the right people in contact. :)

Yes, MSYS2 is being used. We can get supermodel to build on windows and linux in actions.
I've given up on getting MacOS builds for now though. I don't have a Mac to test it on, and I can't really replicate actions environment with docker.
