Bug#975589: transition: gnat-10
The gcc-$V source package builds the Ada compiler (gnat-$V) and
companion libraries (libgnat-$V and libgnat_util-$V).
The default Ada compiler is selected by the gnat package.
In unstable, gnat Depends: gnat-9.
In experimental, gnat Depends: gnat-10.
Ada libraries have specific requirements.
* They must Build-Depend: gnat-$V (in addition to gnat).
* Each -dev package name carries a version, similar to the shared
object version for lib packages. Most changes in the source require
a renaming of the -dev package, and a source upload of all reverse
In order to reduce the number of such transitions, many unrelated
changes, like new upstream releases, are introduced with a libgnat
transition and tested in experimental.
title = "gnat-10";
is_affected = .depends ~ "libgnat-8" | .depends ~ "libgnat-9" | .depends ~ "libgnat-10";
is_good = .depends ~ "libgnat-10";
is_bad = .depends ~ "libgnat-8" | .depends ~ "libgnat-9";
The affected source packages are:
libgnatcoll-db/21.0.0-3 fails to build on mipsel in experimental, and
sometimes on mips64el (#971018, reported at
It won't migrate from unstable to testing.
19.2-3 in testing depends on gnat/9 and will block the transition.
Please remove libgnatcoll-db/19.2-3 from testing.
gnat-gps is removed from testing and RC-buggy in unstable because it
depends on python2 (and libgnatcoll-python below).
Version 19.2-3 in unstable does not build with gnat-10, and fixing
this would be wasted work.
Version 20 is not ready, and won't be part of next release anyways, so
the best option is probably to remove it from unstable for now. It
needs a passage through the NEW queue anyways for unrelated reasons.
Please remove gnat-gps/19.2-3 from unstable.
libgnatcoll-python is removed from testing and RC-buggy in unstable
because it depends on python2 (upstream is working on this).
For now, it builds with gnat-10 and python2 in experimental.
It won't be part of next release, but can be updated like normal
packages and should not prevent the migration of other packages.
These packages mention no versioned -dev. They will only need a
rebuild once their dependencies are available in unstable.
nmu music123_16.6-1 . ANY . -m 'Rebuild with gnat-10)'
nmu topal_80-1 . ANY . -m 'Rebuild with gnat-10)'
nmu whitakers-words_0.2020.10.27-1 . ANY . -m 'Rebuild with gnat-10)'
The gcc-$V and ghdl packages Build-Depend on an explicit gnat version,
but not on the default compiler.
They are not affected.
The ada-reference-manual package requires an Ada compiler for an
intermediate documentation formatter.
It is not affected.
When would a reupload to unstable be appropriate?
