[Buildroot] Build failure on upgrade to 2019.08.1

[Buildroot] Build failure on upgrade to 2019.08.1

[Steve Calfee]

I built the buildroot toolchain in one BR tree, to use as an external
toolchain in another.

Versions:

arm-buildroot-linux-gnueabi-gcc.br_real (Buildroot
2019.11-git-00838-g196e3d2) 8.3.0

And then in another tree I checked out 2019.08.1, loaded in my old
defconfig and then started a build. Fairly quickly in the build I get
this link failure.

The missing file is in the output tree:

So I guess as the failure suggested -rpath is not correct. I assume I
am missing some config option somewhere.

Any suggestions?

 I assume you use it as a preinstalled external toolchain?

 There's no error here, just a warning... But I guess it is followed by some
undefined pthread symbols.

 It's weird though, since the sysroot/lib directory should be in the toolchain's
standard search path.

 Could you run the link command with an additional -v option so we see the
library search path?

Yes, as I have done for several years on many buildroot versions.

Yes, about 4 undefined symbols.

I really appreciate you trying to help. I cannot see how to add a link
option. I tried "make V=2" but with no effect.

The makefile stuff is pretty complicated. The one in the buildroot
base directory does not have a link command that I can see. I tried
just re-entering the command that was sent to the console with make
V=1, but I don't seem to be in the correct directory to issue that
command.

Could you please describe how to add a -v option to the link command?

Thanks, Steve

 I'm asking because the pre-installed external toolchain doesn't get that much
testing. So it is not impossible for it to break.

 However, I just tried a build of dbus with a preinstalled external toolchain
and it completed without a hitch.

 BTW, myself, I never start from a defconfig when I update Buildroot; I start
from a full config. That avoids problems when defaults for some options have
changed. Note however that this can't explain your build failure (and even so it
wouldn't be an excuse :-).

 Yes, that's what I meant: enter the `.../arm-buildroot-linux-gnueabi-gcc
-fno-strict-aliasing ...` command with an additional -v...

 ... from the directory that contains dbus-update-activation-environment.c, i.e.
output/build/dbus-1.12.16/tools/

 You can also also set BR2_DEBUG_WRAPPER=1 in the environment to see the options
that really get passed to gcc.

 Arnout

The legacy options in menuconfig flags the errors. However if you
cannot find my errors I will start again trying your way.

Your path suggestion helped. I did not realize it was failing in the
.../tools/ directory. My complete console session with this link is in
the output below.

I don't see anything obviously wrong in the output. I hope it is not
one of those "order matters" in the link command.

[Buildroot] Build failure on upgrade to 2019.08.1

[Arnout Vandecappelle]

 Hi Steve,

 I'll continue try to debug remotely but it gets harder and harder :-)

 Order matters generally only applies to static linking.

 This is what I wanted to double-check. Looks correct.

 Oh, I hadn't noticed this bit before: you're building the toolchain with
Buildroot master and use it with Buildroot 2019.8.1. Not that it should matter,
but I'll just try that use case now.

[snip]

 Clutching at straws here, but: is this also the location where you originally
built the toolchain, or did you move it around? I would in fact expect
libpthread.so.0 to be in this directory as well..

> -L/home/calfee/edi-workspace/buildroot/output/host/arm-buildroot-linux-gnueabi/sysroot/lib

 So the directory containing libpthread.so.0 *is* included with -L...

 Maybe this .so file has an RPATH and maybe for some reason the linker uses that
instead of -L for the NEEDED entries?

 Or maybe the fact that a -rpath is specified on the command line overrides the
-L options?

 But in either case, I should be able to reproduce...

 Could you post the defconfig for your toolchain and for the failing config?

 Regards,
 Arnout

Hi Arnout,

I am still having the build fail in dbus - could you post the two
configs you used successfully?

[Buildroot] Build failure on upgrade to 2019.08.1

[Steve Calfee]

Hi Arnout,

Still failing in the same way. I am running ubuntu 16.04.6 LTS.

I checked out the same versions as you and built as you said explicitly.

<quote>
built on master of a couple of days ago, using 'make toolchain'
built on 2019.08.x of a couple of days ago, built with `make dbus`.
</quote>

This is very confusing. Maybe something is missing or wrong in my host
environment?

Steve

From my app buildroot dir, I verify libpthread exists - I guess
installed from the toolchain buildroot:

I don't understand why a .so is being used in a link?

In any case, if I change my defconfig to use the pre-built code
sourcery tool chain it no longer fails. So something is wrong with my
toolchain?

Here is a snip from the successful build:
