Description Michael Cook 2020-03-25 21:30:07 UTC
Pretty sure I noticed this failing with clang 10rcs, but I haven't gotten around to investigating it.

It errors out with some linking errors like:

/usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lclangIndex

Reproducible: Always

patch that compiles with clang 10 at least

I'm not sure if there is a better way to do this (like for older clang version checks or something or if those even still work ...)

Comment 3 Matt Turner gentoo-dev 2020-04-24 22:21:06 UTC
I speculatively marked a version bump as closing this because I see that the release notes say it supports clang-10. I don't have clang-10 built to test. If you can confirm whether its now working or not I would be very appreciative. If not, and your patch still fixes it, I'll gladly commit it.
Comment 4 Michael Cook 2020-04-25 01:41:36 UTC
Still need to pass -DCLANG_LINK_CLANG_DYLIB=1 in mycmakeargs for clang 10 to compile (tested 0.20190823.5 as well)

    dev-util/ccls: Pass -DCLANG_LINK_CLANG_DYLIB=1
    
    Fixes the build with clang-10, while evidently not harming the build
    against earlier versions.
    
    Thanks to Michael Cook for the patch.
