Hello,

Thanks for your report!

However, I can not reproduce that build failure.
Here's my defconfig:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_LIBGLIB2=y

This selects an arm926t CPU, which is an armv5. And libglib2
builds correctly here.

Care to share your defconfig, please?

Regards,
Yann E. MORIN.

Based on the error message, the reporter was most likely building with thumb1
mode.

And indeed, it fails here as well with that config +
BR2_ARM_INSTRUCTIONS_THUMB=y

I guess we'll need to force -marm for libglib2.

That TMPDIR seems to indicate that you are building as root. PLEASE don't do
that. One of the most basic features of Buildroot is that you don't need to be
root (and no guarantees are given that it will behave sanely if you DO run it
as root).

The assembly code in question comes from glib/valgrind.h, but unfortunately, I
don't see a way of disabling valgrind "support" from glib.

    libglib2: force arm mode when building with thumb1

    Fixes #8491

    glib/valgrind.h contains inline asm not compatible with thumb1, so build it
    in arm mode:
