Problem with building emulator / firmware

[MasterTimeThief]

Description I cannot build the emulator or the firmware. The issue has hit me two seperate times, both of which I will describe here.

Reproduction Steps

1. The compilation would throw a bunch of warnings from the project, before treating one or more of them as a fatal error and stopping the build. I was able to fix this by going into the makefile and removing -Werror=all from the CFLAGS_WARNINGS variable.

2. After I fixed the previous issue, I tried building the emulator again and ran into a different problem. At first, it gave me an error that said x86_64-w64-mingw32-gcc.exe couldn't be found, so I tried reinstalling msys2 based on the guide. That led me to my current issue, which now gives me no actual errors. It just seems to stop after the first gcc command, and I don't see what's breaking it.

What do you get when you run x86_64-w64-mingw32-gcc.exe --version? For reference, my output is below. If you get something different, that'd be a good lead. Also make sure the order of paths in your PATH variable matches the guide (specifically the python and msys ones)

I don't see the error in your second screenshot either. Maybe try running make clean and make all as separate steps? Just for kicks, you can try running make all a second time too.

As a sidebar, it's better to suppress a specific warning with something like -Wno-error=stringop-overflow rather than turn them all off with -Werror=all

[MasterTimeThief]

My output for gcc is the same as yours, and my path setup is exactly as you have it in the guide too. And yeah, I don't see an error either, that's where I'm stuck. It just shows the first command and then stops. running make clean and make all seperately did the same thing.

My best guess is it's not making the .o file, but I don't know why or how that broke.

[AEFeinstein]

You can check if it's building that object file. It would be generated at ./emulator/obj/emulator/src/emu_main.o. I suspect you're right that it isn't.

It's strange that your compiler and path would match, but still have this issue. You can try running the compile command outside the makefile with this long line. If there is an error message that make is hiding, maybe this will expose it.

It wasn't making the object file, even with the seperate command. However, I decided to try and update my entire msys2 install, and that seems to have fixed the issue. Took me a bit to realize because I had been able to compile the build once, but I may have updated x86_64-w64-mingw32-gcc.exe after that, and the mismatch of versions between that and msys2 as a whole might have been what broke stuff.

Huh, glad you sorted it out. Happy hacking!
