I am getting the same error

@c60cb859 I pinned clang to the version-specific commit and it builds again for me, would you mind trying again?

@ftschindler Could you elaborate on your errors and which of your changes relate to them?

ftschindler commented on 2020-11-20 10:40

@sgsaenger When using clang from /opt/cling, I get compile and linker errors related to non-matching stdc and/or stdc++ libs and includes. I could resolve those and make the llvm/clang from /opt/cling usable for me by incorporating ideas/changes from the llvm and llvm-libs arch packages. If you are interested, the resulting PKGBUILD can be found here.

changing the source, as you suggest does not work for me

ftschindler commented on 2020-11-09 15:18

I am also getting an error, most likely due to an update to the cling-patches branch in clang (since this PKGBUILD tracks branches, rather then revisions). It might make sense to fix known working versions of llvm and clang in the PKGBUILD, as this is not a VCS package. I.e., setting the following in the PKGBUILD works for me:

source=(
    "llvm::git+http://root.cern.ch/git/llvm.git#commit=9c749361ba8c2d400b83d8cc5c544287465b7489"
    "clang::git+http://root.cern.ch/git/clang.git#commit=1681812d1df5d411d6aefe71dec0ae9275e9b2c9"
    "cling::git+http://root.cern.ch/git/cling.git#tag=v0.7"
)

I am getting an error when building this. It just says: A failure occurred in build().
