Hello, I was following [1] to be able to use clang to build packages so I can compile the kernel with Clang, I have an issue with it as I need to use sys-libs/llvm-libunwind. [1] says that sys-libs/llvm-libunwind as a drop-in replacement for sys-libs/libunwind. Unfortunately, net-fs/samba pulls only sys-libs/libunwind and makes it impossible to switch to sys-libs/llvm-libunwind. I edited line 93 of the EBUILD from ```!alpha? ( !sparc? ( sys-libs/libunwind:= ) )``` to ```!alpha? ( !sparc? ( || ( sys-libs/libunwind:= sys-libs/llvm-libunwind ) ) )``` And it seems to build just fine on my machine where I replaced sys-libs/libunwind with sys-libs/llvm-libunwind [1] https://wiki.gentoo.org/wiki/Clang
https://github.com/gentoo/gentoo/pull/20761
This bug is now blocking an update on my system. As Clang now newly depends on sys-devel/llvm-libunwind, but samba pulling in sys-devel/libunwind and both cannot be installed at the same time. Please work on getting the PR ready and merged.

Isn’t it optional on Clang….?

I think as ever, full emerge output would be useful.

(In reply to Jan Henke from comment #2 and comment #6) Your problems are unrelated to this bug. Both sys-devel/clang and sys-libs/libcxxabi depend on either sys-devel/libunwind or sys-devel/llvm-libunwind. Probable cause of your problem is mismatched USE flags: ABI_X86="32" for sys-libs/libcxxabi and sys-libs/llvm-libunwind ABI_X86="-32" for sys-libs/libunwind Since USE flags are satisfied only by sys-libs/llvm-libunwind and not by sys-libs/libunwind, Portage incorrectly suggests switching from sys-libs/libunwind to sys-libs/llvm-libunwind. This happens since: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d10cdcf53d0f254880621200ec882af96c59914e Maybe abi_x86_32 should be enabled by default for sys-libs/libunwind.
Well, I tend to disagree. At least partially it is related to this bug, because samba prevents switching to sys-devel/llvm-libunwind (which would be my preferred sulution anyway). Thus making net-fs/samba support sys-devel/llvm-libunwind as well would allow me to proceed to switch my libunwind. Anyway, I am aware that this is all done by people in their spare time and there is no right to demand any solution. Nevertheless I want to point out that the recent change to sys-devel/clang made this change more urgent, as there is now additional motivation to switch to LLVM's libunwind implementation.
I just got the same dependency issue with clang pulling libunwind with the new change, the new change should include clang 32bit too :thinking: ``` * Error: The above package list contains packages which cannot be * installed at the same time on the same system.

(In reply to Adel KARA SLIMANE from comment #9) As stated in a comment in the PR https://github.com/gentoo/gentoo/pull/20761 clang version 12.0.0-r1 needs now the `llvm-libunwind` USE flag when using `sys-libs/llvm-libunwind` that fixed the dependency issue.
Currently 3 packages have any dependency on sys-libs/llvm-libunwind: - dev-cpp/glog[libunwind] and sys-devel/clang[default-compiler-rt] have "llvm-libunwind" USE flag and have generally this dependency: llvm-libunwind? ( sys-libs/llvm-libunwind ) !llvm-libunwind? ( sys-libs/libunwind ) - sys-libs/libcxxabi[libunwind] is missing "llvm-libunwind" USE flag and has old-style dependency: || ( sys-libs/libunwind sys-libs/llvm-libunwind ) Bug #722992 contains patch for sys-libs/libcxxabi to use "llvm-libunwind" USE flag. || ( ... ) combined with mismatching USE flags (in this case caused by profile) can make Portage's dependency resolver incorrectly suggest switching from one package to another package (sys-libs/libunwind -> sys-libs/llvm-libunwind). After bug #722992 is fixed, the worst what should happen is that Portage's autounmasker will suggest enabling "abi_x86_32" USE flag for sys-libs/libunwind and its dependencies (app-arch/xz-utils, sys-libs/zlib). Users who want to use sys-libs/libunwind should not enable "llvm-libunwind" USE flag (it is disabled by default). Users who want to use sys-libs/llvm-libunwind should enable "llvm-libunwind" USE flag. However support for sys-libs/llvm-libunwind in Gentoo should be considered experimental for now.
Any news here?

I make a pull request https://github.com/gentoo/gentoo/pull/24280 I think that this bug could be closed and create a new one to add the virtual/libunwind package and adjust all the packages that use it, This problem is not only exclusive to net-fs/samba

A USE flag must be added to all pkgs.
