  • Device problem occurs on
    Attempting build for Raspberry Pi 3B+ with gdbserver included

  • Software versions of OpenWrt/LEDE release, packages, etc.
    commit d3bf5ff (HEAD -> master, origin/master, origin/HEAD)
    Author: Jonas Gorski jonas.gorski@gmail.com
    Date: Mon Sep 10 11:42:53 2018 +0200

  • Steps to reproduce
    (I successfully built and ran it without gdbserver.)
    In menuconfig, selected the correct SoC, added Luci, then followed https://openwrt.org/docs/guide-developer/gdb:
    "Compiling Tools" - exactly as described.
    "Add debugging to a package" - option "Global build settings > Compile packages with debugging info" (whether this is activated or not has no effect on the problem)

gdb compilation for the target fails, see error below.

I reverted 2 last commits to the gdb package, to what it was at this commit:
commit 525b8f0
Author: Rosen Penev rosenp@gmail.com
Date: Wed Jun 6 18:22:26 2018 -0700

using these commands:
cd package/devel
git checkout 525b8f0 gdb

and the build succeeded. Looks like the updated gdb

.config is attached.
