I think the problem comes from the last commit of gnatbuild.eclass (1.52)

CPATH is set to "${GNATLIB}/include" and this directory contains unwind.h

So the preprocessor take into account unwind.h from this directory while it should take into account build/gcc/include/unwind.h

build.log for 4.3.3 on ~ppc

same here for 4.3.3 on ~ppc.

[Comment 5 Jabby 2011-06-22 07:34:24 UTC]

commenting export CPATH="${GNATLIB}/include" in gnatbuild.eclass works for me.
You should try it.

So, this is a ppc issue? I don't get that on amd64 or x86. Also, does this happen on 4.4 too? (that one has a new bootstrap and ~ppc in KEYWORDS again) I can pull the unwind.h and repackage the bootstrap, but I would like to know whether this is 4.3 specific and what is the situation with 4.4.

And, how come this was not triggered before? Old bootstraps used that wrapper  that was pulling in -I${libdir}/include for ages already. I must be missing some difference about ppc arch..

George,
1.
I get the bug on my x86 gentoo (with only stable packages)

2.
I cannot test this issue with unstable gnat-gcc-4.4 because
because:
gnat-gcc-4.4.3 fails with configure: error: C compiler cannot create executables
gnat-gcc-4.4.5 fails with configure: error: GNAT is required to build ada

Let me know if you need any other information.

Yea, sorry, new bootstrap for 4.3 x86 (and amd64) is in the works, should fix this. 4.4 is already fine, so you may try that one meanwhile.

Ah, that was sparc, not ppc, that has been updated in 4.4. So, indeed, I may ask for your help little bit later (I will need a tbz2 created by portage). First, though, I need to sort out the issue with ppc in 4.3 then.

please let me know if you'd like to test something on ~ppc.

FYI, i tried this on ~ppc and it works.

The versions 4.3.2 and 4.3.3 do not exist in portage. Is this bug obsolete?

[Comment 12 Pacho Ramos 2014-12-28 15:13:39 UTC]

Have anybody tried with any other 4.3.x version?
