[Buildroot] Cannot build C++ internal toolchain using uclibc-ng

[Buildroot] Cannot build C++ internal toolchain using uclibc-ng

[Michele Bucca]

Hello world, this is my first time using this project after a long
time. I'm trying to build a tiny system with a GUI (Minimal Xorg).
I'm using this as a reference
(https://agentoss.wordpress.com/2011/03/06/building-a-tiny-x-org-linux-system-using-buildroot/)
The problem regards the internal toolchain build: I enabled C++, Wide
Character support and Locale support
When I give the make command it gets stuck tryng to build
hotst-gcc-final-6.4.0: the error is the following:

Is this what you have after a complete rebuild ? Make sure you have the
same error after doing "make clean; make".

See https://buildroot.org/downloads/manual/manual.html#full-rebuild for
more details.

Yes, it shows the same error [1]. By the way here's  the output of a
clean build that I've made with the commands :

make clean
LC_ALL=C make

What Linux distribution and version of this distribution are you using
as the host system ?

Thanks,

My host system is Debian Jessie 8.10 x86_64 Updated just today with
latest packages from the repos

I built your exact defconfig in a Docker container that has Debian
Jessie 8.10 installed, and it worked just fine for me. I only had an
issue way after the toolchain build, when building the kernel, because
your defconfig lacks:

  BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y

But other than that, it builds fine. So I suspect there is something
wrong/special in your environment. As I can't reproduce, you'll have to
investigate a bit yourself I'm afraid.

Best regards,

Thomas
