Description Colin Charles 2005-05-22 15:36:07 UTC
Bootstrap comparison failures existed in March 2005, but is this still prevalent
with regards to the current release of gcc in FC4/devel. So this makes Ada stuff
not work on ppc... Will it be fixed before FC-4 goes out?

gcc-4.0.0-2.ppc is currently whats current on ppc (and other archs)

Comment 1 Jakub Jelinek 2005-05-23 07:52:47 UTC
For FC-5 maybe, for FC-4 definitely not.  Ada is certainly low priority and
adding a new Ada arch because of the Ada bootstrap requirements is time

Comment 2 David Woodhouse 2006-12-28 11:46:48 UTC
Was this related to and is it
now fixed? Would be good to have this fixed by FC7, so reopening.

Jakub, if you want to reclose it please could you make sure there's a current
bug in GCC bugzilla and set the resolution to 'UPSTREAM'?

Comment 3 David Woodhouse 2006-12-28 18:57:09 UTC
I'm told that gnat should now be working -- we just need to get it bootstrapped.

To test that theory I'm doing a test build of gcc-4.1.1 with %build_ada enabled,
building with FC2's gcc-3.3.3.

Comment 4 David Woodhouse 2006-12-29 11:52:34 UTC
That build seems to work (although it failed at the final hurdle because I'd set
%buildjava to zero to speed it up so it had some files missing).

It had already populated the buildroot though, and the resulting gnat files from
a 32-bit build (along with the compiler driver /usr/bin/gcc) are at

I'm not entirely sure how to use these to bootstrap Ada in brew -- perhaps by
including the tarball (and a similarly-generated 64-bit tarball) as 'source'
files in the package for one build, then rebuilding 'properly' once it's managed
to spit out gcc-gnat and libgnat into the build system?

Or maybe by creating a special buildroot for it which contains FC2's gcc-3.3.3
packages instead of the current FC6 compiler, then just doing normal ppc and
ppc64 builds and letting those get inherited into the FC7 system?

Jesse will know; Jesse likes bootstrapping things.

Comment 5 Jesse Keating 2006-12-29 16:26:20 UTC
Gee, thanks (:

Either method should work, using tarballs is slightly less work then creating a
special buildroot.  Either way I'll be able to help you when I return from
forced holiday.

Comment 6 David Woodhouse 2006-12-30 20:41:55 UTC
32-bit packages seem fine, and are uploaded to

The 64-bit package failed though -- is this because I was building it on a
"normal" system and not a pure 64-bit buildroot, or is it a real problem?

bootstrap patch for specfile

A scratch build of gcc-4.1.1-50.ada is running with this patch now, as a test.
If the result is successful, we should be able to build once with this in
dist-fc7, then back out all but the first hunk and build again. Perhaps even
FC-6 too?

I've tested GtkAda and ghdl with the manually bootstrapped gcc-gnat; I'll do so
again with the packages which this test build spits out.
