Comment 2 orbea 2023-11-21 16:20:57 UTC
I can't reproduce this using slibtool, musl, clang and the same USE. Looking at the error I would guess this is related to ar(1) and not slibtool.

ar: error: script line 1: unknown command: OPEN

Are you sure this is not reproducible with libtool?
Comment 3 topological-automata 2023-11-23 19:34:23 UTC
yes, because with libtool, same env it compiles fine, no problem..
Comment 4 orbea 2023-11-23 22:10:11 UTC
What ar(1) implementation are you using and how did you configure it to be used?
Comment 5 orbea 2023-11-24 16:26:39 UTC
I was able to reproduce it, this occurs with slibtool + llvm-ar and seems likely to be a slibtool bug.

With GNU libtool it will call clang and then use llvm-ar appropriately, while with slibtool it will just use the ar executable which will work if that ar executable is from binutils, but if its actually a symlink for llvm-ar then it will fail as shown in this issue.

At least in the cast of libxml2 this can be avoided by not setting static-libs in the USE.
Comment 6 orbea 2024-02-08 17:00:38 UTC
This is fixed in slibtool-9999 and will be fixed in the next release.

    dev-build/slibtool: add 0.5.36
    
    Many bugs are fixed with this release, it is recommended for slibtool
    users to rebuild their entire system after this release. The addition of
    -export-symbols and -export-symbols-regex will allow exporting only the
    desired public symbols globally in any package that uses them.
