From 78d517a18cf32402eac016d92d7bb8cc8b586119 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Thu, 24 Apr 2025 12:31:30 +0200 Subject: [PATCH] toolchain: gdb: set -std=gnu17 Fedora 42 updated to GCC15 which now defaults to GNU23 as the default instead of GNU17[1], and this breaks gdb compilation. This looks like a readline issue, that was fixed in GDB 16.2 but to not update toolchain components we can simply set the C standard back to GNU17.
