Subject: [Buildroot] [PATCH 1/1] package/mdevd: fix build with glibc >= 2.43
Date: Sat, 4 Apr 2026 08:56:35 +0200 [thread overview]
Message-ID: <20260404065635.334754-1-bernd@kuhls.net> (raw)
Buildroot commit 227378b5930b681c79a13476ae60a98753a98a03 bumped glibc
to 2.43 causing a build error in mdevd:
src/mdevd/mdevd.c: In function 'act_on_event':
src/mdevd/mdevd.c:797:36: error: assignment of read-only location
'*(const char *)strchr(ud->devname, 10)'
797 | *strchr(ud->devname, '\n') = 0 ;
Add upstream commit to fix the problem.
