I have dev-lang/gnat-gpl-2021-r5[bootstrap] emerged, but it seems to provide no Ada support, i.e., no gnatmake or other gnat* binaries. I have already tried re-emerging gnat-gpl a couple times and while it emerges sucessfully, situation doesn't change. Reproducible: Always Steps to Reproduce: 1. emerge dev-lang/gnat-gpl-2021-r5 Actual Results: No gnatmake Expected Results: gnatmake present # emerge --info gnat-gpl Portage 3.0.65 (python

Created attachment 899853 [details] files list installed by the package This is what files gnat-gpl has installed on my system, as determined by `equery files gnat-gpl`
Are you sure you enabled the ada use flag? Like USE=ada emerge gnat-gpl?
Yes, very sure. It's also shown in the emerge --info gnat-gpl output above (near bottom). I checked a little more what the build is doing. It seems in configure step it configures just for `Languages: c` contrary to what USE-flags should instruct it to. No clue why though.
OK, I went on a hunch and tried running USE="cxx" ebuild /usr/portage/dev-lang/gnat-gpl/gnat-gpl-2021-r5.ebuild configure and it suddenly gave me `Languages: c,c++,ada`. That might mean `ada` USE-flag requires `cxx` USE-flag.
Yes, cxx is also required to build ada. So ada is disabled when cxx is not enabled. I remember that a warning message saying that is sent with elog
well, no, This is the check we do: is_ada() { gcc-lang-supported ada || return 1 _tc_use_if_iuse cxx && _tc_use_if_iuse ada } Both cxx and ada USE flags should be enabled, and gcc should have support for ada
OK, I located the relevant snippet in toolchain.eclass and see it now. The issue is that it did happen silently. Maybe REQUIRED_USE="ada? (cxx)" for dev-lang/gnat-gpl at least?

Started looking at this after https://public-inbox.gentoo.org/gentoo-dev/2a700166-f01a-4807-bd76-7b0cce72af0b@archeia.com/ although the approach is different. I did use it as a base although not much of it remains. We take the following approach: * Iterate over installed GCC slots (preferring ${SLOT}, then iterating from the latest version installed down to GCC 10) to find a copy of GNAT; * Create wrappers for gnat* to redirect calls when building GCC to our found bootstrap copy of GNAT; * Use an extracted spec file to redirect gnat1 calls to that bootstrap copy too, as the build system doesn't allow saying "just use this copy of gnat" (it always wants $(CC) to support it). The real nasty part here is that GCC's build system doesn't seem to have a way to point to 'ADACC' or similar (it looks like it did have 'ADAC' years ago). Remaining bits to be done: * Adapting/replacing/supplementing dev-lang/gnat-gpl with a version that can be installed in parallel to sys-devel/gcc:10 so it can be pulled in transparently for bootstrapping; * Build our own, or source some other copy (e.g. from Alire), of a newer bootstrap GNAT. https://github.com/alire-project/GNAT-FSF-builds is a likely candidate. I also hope that we can ultimately do the same for D.
