Link errors when attempting to use external LLVM & Clang

Open apteryks opened this issue 4 years ago • 2 comments

Describe the bug

When using LLVM and Clang as external dependencies (but built using their patched sources), Cling fails to link, showing various missing LLVM symbols.

See ba63aikq9ym2n7gjs13m56hxa77q25-cling-0.9-1.d78d1a0.drv.txt for the complete build log.

Expected behavior

Cling should build successfully.

To Reproduce

  1. Install Guix following https://guix.gnu.org/manual/en/html_node/Binary-Installation.html.
  2. Checktout https://gitlab.com/Apteryks/guix/-/commits/cling and build Guix following and http://guix.gnu.org/manual/en/html_node/Building-from-Git.html#Building-from-Git
  3. From the Guix checkout, run: ./pre-inst-env guix build cling

Setup

  1. Cling version 0.9, commit d78d1a03fedfd2bf6d2b6ff295aca576d98940df.
  2. Operating system Guix System
  3. From sources

Seems adding a link directive for clang-cpp resolves the issue, at least for libcling.

I've done the same for tools/driver and now I got a cling binary, but it fails to run like:

$ /gnu/store/zk5laplbwxncqjr8x3jsfrw73pvn4aly-cling-0.9-1.d78d1a0/bin/cling --help
: CommandLine Error: Option 'disable-symbolication' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
