System: Darwin 24.6.0 Darwin Kernel Version 24.6.0: Wed Oct 15 21:12:21 PDT
2025; root:xnu-11417.140.69.703.14~1/RELEASE_X86_64 x86_64
>Description:
avr-gcc does not compile on recent macOS SDK >= 26.1. The issue is
related to the replacement of ctype.h with safe-ctype.h in the gcc 13.2
source. The safe-ctype.h header enforce that islower isalpha and other
functions are not used. However, the macOS SDK does use them causing the
compilation to fail.
>How-To-Repeat:
Simply run `bmake build`.
>Fix:
Below is a easy solution that adds a patch to the gcc source code,
disabling the replacement of islower, isalpha, etc on Darwin platform.
