From 600ce3a71e8284b55d4c385015136c2c5ccb4079 Mon Sep 17 00:00:00 2001 From: Yegor Yefremov Date: Tue, 20 Oct 2026 15:53:00 +0200 Subject: [PATCH] package/mg: needs a toolchain with wchar support Since version 4.2, mg uses iswalnum() from to tell whether a UTF-8 character is part of a word (upstream commit ee22ef729b16 "Tell UTF-8 words by their Unicode class"). This breaks the build with toolchains that lack wide character support, such as uClibc without WCHAR: utf8.c:23:10: fatal error: wctype.h: No such file or directory 23 | #include | ^~~~~~~~~~ Add a dependency on BR2_USE_WCHAR, together with the matching comment. This issue has been present since commit 3b5fbe8f6e78 ("package/mg: bump to v4.4"), which updated mg from 4.1, so it pulled in this change. That commit is not part of any release nor of any maintenance branch yet, so only master is affected.
