Error logfile with ARM linaro toolchain 2018.05 and qt5.12.2

Hi buildroot team

I am using the latest stable Buildroot version 2019.05.1, but I am facing a
builderror with the qt5webengine and I hope, that someone could help me out
with this issue.

My setup:
From a hardware point of view, I am using a Ka-Ro TX6QP computer-on-module with
an i.mx6 (ARM Cortex-A9) processor. For this reason, I am using the Linaro ARM
2018.05 toolchain (Proposed by Buildroot 2019.05.1). The goal is to build the
qt5webengine (Latest: Qt5.12.2) successfully.

The challenge, I am facing right now:
I wanted to build the qt5webengine, but I got several error messages in this
style:

> /home/patrickk/tmp/buildroot/buildroot-2019.05.1/buildroot-2019.05.1/output/host/opt/ext-toolchain/arm-linux-gnueabihf/include/c++/7.3.1/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
>  #include_next <stdlib.h>
>                ^~~~~~~~~~
> compilation terminated.

A quick google search (https://bugreports.qt.io/browse/QTBUG-53367) showed a
known problem with new GCC > 4.8 versions in respect of the argument
"-isystem". Nevertheless, I was not able to solve my described problem at the
source.

Next, I tried to update the linaro toolchain to the newest available version,
but the same error showed off...
Link:
https://releases.linaro.org/components/toolchain/binaries/7.4-2019.02/arm-linux-gnueabihf/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf.tar.xz

My last attempt was to update Qt5 to version 5.13.0. This showed the following
error:
> In file included from ../../3rdparty/chromium/sandbox/linux/seccomp-bpf-helpers/syscall_parameters_restrictions.cc:25:0:
> ../../3rdparty/chromium/sandbox/linux/seccomp-bpf-helpers/syscall_parameters_restrictions.cc: In function ?sandbox::bpf_dsl::ResultExpr sandbox::RestrictPtrace()?:
> ../../3rdparty/chromium/sandbox/linux/seccomp-bpf-helpers/syscall_parameters_restrictions.cc:401:9: error: ?PTRACE_GET_THREAD_AREA? was not declared in this scope
>          PTRACE_GET_THREAD_AREA,
>          ^
I am not sure, if my update from Qt5.12..2 to Qt5.13.0 solved the first error
or even introduced a second error...

It would be awesome, if someone could help me out or give me a hint. I
appreciate every support I get
I attached my .config file to this e-mail. If you need additional information,
please do not hesitate to contact me.
Thanks in advance.

Hello Patrick,

this bug has already been fixed here with this commit:
https://git.busybox.net/buildroot/commit/?id=3a0ed5d25e26cb2ec99a1da077c9dcfea67b0ecc

What makes it show again is that you specify '-device imx6' in
BR2_PACKAGE_QT5BASE_CUSTOM_CONF_OPTS.

When buildroot builds qt5 expects to use device 'buildroot' that is based on
qmake.conf.in in 'package/qt5/qt5base/'

So basically you're telling to qt5 to ignore buildroot qt5 configuration.

You should only remove '-device imx6' from your
BR2_PACKAGE_QT5BASE_CUSTOM_CONF_OPTS.

What is passed to qt5 build system when '-device imx6' is specified should be
implicit when you choose the correct compiler. I mean these:
IMX6_CFLAGS             = -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1

So if you compile for armv7-a with neon enable you should be ok.

Anyway I've tried this using master branch and I get a GCC ICE :/ and need to
dig deeper.

But please, give a try with 2019.05.1 and let me know.

Thank you!

Giulio

Ah, just checked, you need to select 'neon' instead of 'VFPv3' as fpu

Hi Giulio

Welcome back! I hope, you enjoyed your holiday to the fullest :)

Thanks for your help, I really appreciate your support.
I just applied your suggested changes to my configuration, but
another error showed up. Let me first tell you, what I did:

- Removed "-device imx6" from BR2_PACKAGE_QT5BASE_CUSTOM_CONF_OPTS
- Changed floating point strategy to NEON
- make clean && make

The qt5base build process failed due to the following error:

ERROR: Feature 'eglfs' was enabled, but the pre-condition
'!config.android && !config.darwin && !config.win32 && features.egl' failed.
(Log-File: 190829_error_no_device_and_neon)

Do you know, what is going on and could you please give me a hint?

Thanks a lot :)

Hi Patrick,

can you confirm me that you're using:
- buildroot 2019.05.1
- attached .config file
- qt 5.12.x

Right?

Because I need this to reproduce your bug.

Ah, can you:
- make savedefconfig
And attach resulting defconfig here?

Also, are you sure you're using buildroot 2019.05.1 with no modifications?

Hi Giulio

Thanks for getting in touch again. Here are your requested informations:

- I am using buildroot 2019.05.1
- I attached my .config file (190829_buildroot_config.tar.gz)
- I want to build Qt 5.12.2

I am sorry, but "make savedefconfig" failed... I don't know why:

make savedefconfig
n*** Error while saving defconfig to:
/home/patrickk/tmp/buildroot/buildroot-2019.05.1/buildroot-2019.05.1/configs/polytab_defconfig

Makefile:1008: recipe for target 'savedefconfig' failed
make: *** [savedefconfig] Error 1

Thanks a lot.

I can't reproduce your error.
Unfortunately I get NS(x) error instead of yours.

Have you got the chance to join IRC channel for live speaking?
Otherwise it could take lot of time to solve this.

The 2019.05.x series is no longer supported, and qt5webengine has been bumped
since, so closing the issue. Please reopen with more details if you still see
the issue, thanks.
