Error occurs while trying to compile production target keyboard firmware about qmk_firmware

[zvecr]

Issue is due to differences in avr-gcc compiler version. Some have known regressions when it comes to generated code size and not really a QMK bug.

8.x has been mentioned as good, 13 as used above builds fine.

Should I update avr-gcc using pacman?: pacman -S avr-gcc

Or is there some other/preferred way of doing it using the QMK CLI?

[MaxJ345]

Actually, I don't see avr-gcc listed by pacman as an installed package.

How do I set the version of avr-gcc used by QMK?

[zvecr]

https://packages.msys2.org/package/mingw-w64-x86_64-avr-gcc 12.2.0 is the latest available for MSYS.

[MaxJ345]

So how did you get QMK to compile with avr-gcc version 13.2.0 above?

[tzarc]

Put simply, I don't use QMK MSYS; different Linux distributions bundle different compiler versions, and in my case, I've compiled my own copy of gcc 13.2.0 to run under Linux.

Ultimately this is outside the scope of QMK's support -- we make a best-effort attempt at getting things to work on as many operating system combinations as possible, but with the number of people we have and the numerous variations in the wild, we can't support everything. We don't have control over which version of GCC is packaged by the MSYS team, and at the moment I'd hazard a guess and say that almost nobody can build production targets under QMK MSYS.

If it's critical that you build production targets, your best bet is to figure out an alternative compilation environment such as Linux. If you can run Docker locally you can try to use the prebuilt QMK CLI container which contains an older version of GCC (in the 8.x series) which under normal circumstances should work fine. Neither of these solutions are going to be as simple to get working as QMK MSYS.

EDIT: Arch Linux has 13.2.0, for example: https://archlinux.org/packages/?sort=&q=avr&maintainer=&flagged=

[MaxJ345]

I see. That's unfortunate.

I'll try to see if I can get it working in a Linux-based environment. Thank you for your help!
