So, as a developer that likes to test with multiple compilers, I have several versions of clang/llvm installed. Unfortunately, the thunderbird package wants to switch versions pretty much every time I do: emerge -auDN @world. Currently, I have lld-9.0.0 installed, and I see lines like this: [ebuild UD ] sys-devel/lld-8.0.1 [9.0.0] But if I let that go through and downgrade lld, then in a subsequent world update, it'll try to upgrade it again to 9.0.0. This is a relatively recent issue. Reproducible: Always emerge --info Portage 2.3.76 (python 3.6.9-final-0, default/linux/amd64/17.1/desktop, gcc-9.2.0, glibc-2.29-r2, 5.2.19-gentoo x86_64)

How do you "switch"? Keep in mind that you are on amd64 (stable). clang/llvm-9 is not stable. So when you want to play with -9* stuff you have to keyword *everything* from that family. It's your responsibility to ensure that all requirements are satisfied. You are seeing downgrades because you haven't keyworded all required stuff. Now portage is forced to get at least one working clang/llvm environment set up. And for amd64 this is -8* at the moment... You can't mix sys-devel/llvm, sys-devel/lld, sys-devel/clang... versions. When you want to use version 9.x you have to use version 9 for the _complete family_.
Well, the packages are slotted, so that means that they should be able to coexist at the same time, right? I have the following package.keywords for clang/llvm: =sys-devel/clang-9* ~amd64 =sys-devel/clang-common-9* ~amd64 =sys-devel/clang-runtime-9* ~amd64 =sys-devel/lld-9* ~amd64 =sys-devel/llvm-9* ~amd64 =sys-devel/llvm-common-9* ~amd64 =sys-devel/llvmgold-9 ~amd64 =sys-libs/compiler-rt-9* ~amd64 =sys-libs/compiler-rt-sanitizers-9* ~amd64 =sys-libs/libcxx-9* ~amd64 =sys-libs/libcxxabi-9* ~amd64 =sys-libs/libomp-9* ~amd64 Which I believe covers all of the 9.x needs. The way that I "switch", is by invoking directly, clang++-8, clang++-9, etc.
> Well, the packages are slotted, so that means that they should be able to coexist at the same time, right? Sure but have to make sure that you keyworded complete depgraph. Run ebuild through `ebuild` command, i.e. $ cd /var/db/repos/gentoo/mail-client/thunderbird $ ebuild thunderbird-68.1.2.ebuild clean configure You will get a message why slot 9 for example was ignored.
OK, I see what the problem is. I'm using stable thunderbird-60.9.0, which doesn't account for clang-9. I'll bump thunderbird to the latest, it looks like it should handle it correctly. Thanks for your time.
Oh, I forgot that thunderbird-60.x also uses clang. Will backport https://gitweb.gentoo.org/repo/gentoo.git/commit/mail-client/thunderbird?id=fae350e462db530ef871b04a5f335d3bd4ce2474. Thanks.
