config.log
We're looking to kill gnat-gpl in favour of ada-bootstrap. Does that work? I guess I need to enable system-bootstrap useflag which is disabled by default, I'll let you know No, I don't think so. The eclass doesn't depend on gnat-gpl anymore and everything should Just Work if you enable USE=ada on sys-devel/gcc. I have installed only latest gcc 14.2.1, if I do # USE=ada emerge -1 sys-devel/gcc -pv [ebuild N ] dev-lang/ada-bootstrap-11::gentoo 44720 KiB [ebuild NS ] sys-devel/gcc-11.5.0:11::gentoo [14.2.1_p20241221:14::gentoo] USE="ada* cet (cxx) fortran (multilib) nls openmp (pie) sanitize ssp zstd (-custom-cflags) -d -debug -doc (-fixed-point) -go -graphite -hardened -jit (-libssp) -lto -objc -objc++ -objc-gc (-pch) -pgo -systemtap -test -valgrind -vanilla -vtv (-default-stack-clash-protection%*) (-default-znow%*) (-ieee-long-double%) (-modula2%) (-rust%) (-time64%)" 80487 KiB [ebuild NS ] sys-devel/gcc-12.4.1_p20241219:12::gentoo [14.2.1_p20241221:14::gentoo] USE="ada* cet (cxx) (default-stack-clash-protection) (default-znow) fortran (multilib) nls openmp (pie) sanitize ssp zstd (-custom-cflags) -d -debug -doc (-fixed-point) -go -graphite -hardened (-ieee-long-double) -jit (-libssp) -lto -objc -objc++ -objc-gc (-pch) -pgo -systemtap -test -valgrind -vanilla -vtv (-modula2%) (-rust%) (-time64%)" 78065 KiB [ebuild NS ] sys-devel/gcc-13.3.1_p20241220:13::gentoo [14.2.1_p20241221:14::gentoo] USE="ada* cet (cxx) (default-stack-clash-protection) (default-znow) fortran (multilib) nls openmp (pie) sanitize ssp zstd (-custom-cflags) -d -debug -doc (-fixed-point) -go -graphite -hardened (-ieee-long-double) -jit (-libssp) -lto -modula2 -objc -objc++ -objc-gc (-pch) -pgo -systemtap -test -valgrind -vanilla -vtv (-rust%) (-time64%)" 82573 KiB [ebuild R ] sys-devel/gcc-14.2.1_p20241221:14::gentoo USE="ada* cet (cxx) (default-stack-clash-protection) (default-znow) fortran (multilib) nls openmp (pie) sanitize ssp zstd (-custom-cflags) -d -debug -doc (-fixed-point) -go -graphite -hardened (-ieee-long-double) -jit (-libssp) -lto -modula2 -objc -objc++ -objc-gc (-pch) -pgo -rust -systemtap -test (-time64) -valgrind -vanilla -vtv" 0 KiB Total: 5 packages (1 new, 3 in new slots, 1 reinstall), Size of downloads: 285844 KiB Why does it pull three gcc versions now? See bug 947587. There's a workaround listed in there too. I masked older versions of gcc and rebuilt gcc with ada useflag.

Then I tried emerging gnap-gpl but it still fails in the same way as described above.
So I started building gnat-gpl with USE=system-bootstrap and I get the following

The Fortran flags are not filtered, the result is that the building still fails as already described

I don't understand why you're emerging gnat-gpl at all. I'm trying to say that it's obsolete and it's going to be removed shortly. You don't need it. All you need is sys-devel/gcc[ada], and it'll pull in dev-lang/ada-bootstrap as-required to fulfil the former role of gnat-gpl. I'm not trying to merge it directly, it is a dep of another package in portage: $ emerge -pv ghdl [ebuild N ] dev-lang/gnat-gpl-2021-r5:10::gentoo USE="(ada) cet (cxx) fortran multilib nls openmp pie sanitize ssp -d -debug -default-stack-clash-protection -default-znow -doc (-fixed-point) (-go) -graphite -hardened (-jit) -libgdiagnostics -libssp (-lto) -modula2 -objc -objc++ -objc-gc (-pch) (-pgo) -rust -system-bootstrap -systemtap -test (-time64) -vanilla -vtv -zstd" 0 KiB [ebuild N ] sci-electronics/ghdl-4.1.0-r1::gentoo USE="static-libs -llvm" ADA_TARGET="gcc_14 gnat_2021 -gcc_12 -gcc_13 -gcc_15" LLVM_SLOT="17 -16" 0 KiB Seems it's a straggler (though I don't get why it's enabled there for you). ghdl has ADA_COMPAT=( gnat_2021 gcc_13 ) (In reply to Fabio Rossi from comment #11) > ghdl has ADA_COMPAT=( gnat_2021 gcc_13 ) But you have: `ADA_TARGET="gcc_14 gnat_2021 [...]"`. Do you have a package.use for it or something? Ok, I found the problem. I had an old package.use forcing ada_target_gnat_2021 for ghdl (the system is new but I copied the old files from the older system where I am upgrading from). After removing the offending line I finally get:
!!! The ebuild selected to satisfy "ghdl" has unmet requirements.
- sci-electronics/ghdl-4.1.0-r1::gentoo USE="static-libs -llvm" ABI_X86="(64)" ADA_TARGET="gcc_14 -gcc_12 -gcc_13 -gcc_15 -gnat_2021" LLVM_SLOT="17 -16"
The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( ada_target_gnat_2021 ada_target_gcc_13 )
The above constraints are a subset of the following complete expression:
exactly-one-of ( ada_target_gnat_2021 ada_target_gcc_13 ) llvm? ( static-libs ) exactly-one-of ( llvm_slot_16 llvm_slot_17 )
which is a matter of building gcc-13 or trying to extend ADA_COMPAT of ghdl
Thanks for the help!

No problem -- and thanks for the motivation to finally last-rite it ;) The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=50d9cf48986effb0baf5d92103137e7902d6ae5d commit 50d9cf48986effb0baf5d92103137e7902d6ae5d Author: Sam James <sam@gentoo.org> AuthorDate: 2025-03-10 00:03:17 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2025-03-10 01:54:29 +0000 ada.eclass: drop gnat_2021 (dev-lang/gnat-gpl) support dev-lang/gnat-gpl is being last-rited.
