[SOLVED] sys-libs/libomp Update Fails to Emerge on Gentoo…

[RandomDSdevel]

(Note: This thread's old, full title was 'sys-libs/libomp Update Fails to Emerge on Gentoo on WSL2,' but it wouldn't fit when I marked it as solved by editing that.)

`sys-libs/libomp` keeps failing to build for me on the Gentoo instance I have running on/under Windows Subsystem for Linux v2 with an error saying that it can't find `libunwind.a`:

Code: Select all

I'm positive I have `sys-libs/llvm-libunwind`'s static library built, though:

Code: Select all

… # equery --no-pipe --no-color uses sys-libs/llvm-libunwind

 + + abi_x86_32  : 32-bit (x86) libraries
 - - debug       : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
 + + static-libs : Build static versions of dynamic libraries as well
 - - test        : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

(Edits:

1. Link BB code syntax fixed.
2. Removed a mention of an unrelated issue with `sys-devel/llvm`.)

[RandomDSdevel]

Never mind; I was confused when I thought the `sys-devel/llvm` issue was related; it isn't. I've removed mention of it from my OP and will start a new, separate thread for it. (Edit: I"ve now done that here.)

Moved from Portage & Programming to Duplicate Threads.

And moved back. Sorry for the mistake.

Thanks, and it happens to everyone, so no problem.

[RandomDSdevel]

For this issue, I'm going to try using my `compiler-clang` environment with no LTO (my default Clang environment has ThinLTO enabled) and see if that works.

[RandomDSdevel]

(Facepalms.) Actually, given the output from my OP, let's see if resolving my other issue doesn't also fix this one, but…maaay-be keep this thread open until we're sure that's the case…? (Shrugs.)

[RandomDSdevel]

Fixing my other issue solved this one.
