Hello,
I noted that I can't build the RTEMS 5 toolchain if I have a modern LLVM
installed using the RTEMS source builder. Therefore I would like to
backport the patch 37ad446d9dce3 ([1]) to the 5 branch. Is that OK? If
someone acknowledges it, I would do the following steps without further
review (but of course with testing):
1. Create a ticket for the problem.
2. In rtems-tools: Cherry pick the patch 37ad446d9dce3 to the 5 branch.
3. In rtems-source-builder: Backport the patch 91932d0a0 [2] to the 5
branch (or rather re-create it because it will be a different commit and
a different hash).
I'm ok with this. I remember doing a patch for the opposite direction.
I couldn't
build on an older gcc because it assumed a different language version as
default. gcc 4.8 as on CentOS 7 assumes C++03. Newer versions assume C++11
as the base. Similarly newer gcc's seem to default to C11.
Thanks. I'll wait a bit more before adding the patches in case someone
else want's to object.
I posted a few weeks ago that users should really be careful to always use
-std and consciously pick what they want.
In this case, the version of the standard depends quite a lot on the
LLVM headers. LLVM seems to love using new features.
Best regards
Christian
