Description Colin Charles 2005-05-22 11:36:07 EDT
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 03:52:47 EDT
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 06:46:48 EST
Was this related to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10129 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 13:57:09 EST
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 06:52:34 EST
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 11:26:20 EST
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.

32-bit packages seem fine, and are uploaded to ftp://ftp.infradead.org/pub/fc6-ada/

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.
