Bug#1075931: llvm-toolchain-18: Broken symbolic links in llvm packages

Fri Jul 19 04:44:13 BST 2024

Dear Maintainer,

Seems that the broken symbolic links mentioned above have been fixed in
*1:18.1.8-4*,  so please close this issue (#1075931). Thanks for the
attention.

Install llvm-toochain-18 packages ( 1:18.1.8-4 ) in an AMD64 schroot:

# apt-get -V --auto-remove --purge --no-install-recommends install bolt-18
clang-18 clangd-18 clang-format-18 clang-tidy-18 clang-tools-18 flang-18
libbolt-18-dev libc++1-18 libc++-18-dev libc++abi1-18 libc++abi-18-dev
libclang1-18 libclang-18-dev libclang-common-18-dev libclang-cpp18
libclang-cpp18-dev libclang-rt-18-dev libflang-18-dev libfuzzer-18-dev
liblld-18 liblld-18-dev liblldb-18 liblldb-18-dev libllvm18
libllvm-18-ocaml-dev libllvmlibc-18-dev libmlir-18 libmlir-18-dev
libomp-18-dev libomp5-18 libpolly-18-dev libunwind-18 libunwind-18-dev
lld-18 lldb-18 llvm-18 llvm-18-dev llvm-18-linker-tools llvm-18-runtime
llvm-18-tools mlir-18-tools python3-clang-18 python3-lldb-18
