Example dimmer project for running SimAVR (with an ATTINY85)

Mhm. There isn’t any actual error message. The linker just exits (or crashes?) with error code 5.

I added the GCC from as referenced winlibs.com, yours seems to be in that msys64/ucrt64 MSys2 environment, I don’t know if you can just call into that compiler from your regular Windows environment instead of from a ucrt64 shell. (And also I would use MinGW64 instead of ucrt64).

Plus you’re missing a few of the linker options
