Hi all.
I'm trying to build gcc on target but it fails with

[Buildroot] gcc on target system issue

Dear Alexander Khryukin,

Why are you trying to build gcc on target? What is the purpose of
getting gcc on the target when building a small embedded Linux system
with Buildroot?

Notice that as per the decisions taken during the last Buildroot
Developers Meeting, the possibility of building gcc for the target in
Buildroot should soon be deprecated. So there is not a strong interest
to fix problems reported by users.

Thanks,

Thomas

Ah, it bad solution to deprecate gcc on target.
i'm embedded linux developer and trying to build OpenMandriva linux
for cortex-a9, but without gcc on target my work is totally unuseful.

Ok, but is buildroot the right tool for that job? It would imho make
more sense to install a full blown distribution supporting ARM
(Debian/Fedora/Ubuntu/..) and use that to rebuild the mandriva packages.

I want  generate image for few archs like cortex a8 with hardfloat,
without, cortex-a9 with\withou, etc.
few months ago buildroot was selected as the best solution
Now i finished to adding all distro-dependent packages and trouble only
with gcc

  Well, the problem is that it is more or less broken (as you can testify), and
that nobody is motivated to invest energy into making it work.  If you find the
time and resources to fix and maintain gcc on target, and you have a relevant
use case, then there is a possibility to undeprecate it again.
