Hi Emmanuel,

HOST_GCC is your host compiler, the Linaro toolchain the cross compiler.

HOST_GCC refers to the toolchain on your build machine. Since it is 
improbable your host computer has a compiler with version < 5 installed, 
something must be wrong in your configuration or the way you start the 
Buildroot make. Do you have environment variables set related to 
compiler or cross compiling? The host path should not contain the target 
toolchain,@least not in first place ...

Buildroot parses the output of 'gcc --version' to eventually set the 
BR2_HOST_GCC_AT_LEAST variables, so maybe start looking there.

Kind regards,
Andreas

Hi Emmanuel,

You already found it by yourself: the 2018 version stops at gcc-8; gcc-9 
was added in Feb 2020. [1]

I can think of three options:

(1) Patch your current Buildroot installation (no support)
(2) Upgrade to Buildroot 2020.02 (may break your target firmware)
(3) Install gcc 8.x on your host machine

Any specific reason for the 2018.11 version?

Kind regards,
Andreas

Sorry Andreas ..
Reason is the initial project was with this version.

No problem.

You could try a quick port. Export /import your defconfig into a more 
recent Buildroot version. If this builds with less problems, stick with 
the new version, otherwise recreate the original build environment, 
starting with the Linux distribution.

Kind regards,
Andreas

OK, I think I understand what's happened... my linux computer is an ubuntu
20.04 with host gcc 9.
but in the version 2018.11.4, there are no case in ../buildroot/config.in
for version 9, so the gcc host identification is broken.

Could somebody confirm ?

Hello all,

I am the wink link! :-/
I build buildroot 2018.11.4 with external toolchain linaro-7.3-2018.05.
I could not activate the QT5WEBENGINE because I have
