Failed to install on Ubuntu 23.04

[AlixANNERAUD]

Hello,
I tried to c2rust with different version of LLVM (13, 14 and 15), but it fails, even with the master branch or the corresponding (feature/llvm-X) branch. I get the following errors related to c2rust-ast-exporter :

error: failed to run custom build command for `c2rust-ast-exporter v0.16.0 (/home/alix_anneraud/.cargo/git/checkouts/c2rust-2a3ef4c32beab81a/b2b8b13/c2rust-ast-exporter)`

Caused by:
  process didn't exit successfully: `/tmp/cargo-installhCisjl/release/build/c2rust-ast-exporter-97a474bdf8914381/build-script-build` (exit status: 101)

  CMake Warning (dev) at /usr/share/cmake-3.25/Modules/ExternalProject.cmake:3075 (message):
    The DOWNLOAD_EXTRACT_TIMESTAMP option was not given and policy CMP0135 is
    not set.  The policy's OLD behavior will be used.  When using a URL
    download, the timestamps of extracted files should preferably be that of
    the time of extraction, otherwise code that depends on the extracted
    contents might not be rebuilt if the URL changes.  The OLD behavior
    preserves the timestamps from the archive instead, but this is usually not
    what you want.  Update your project to the NEW behavior or specify the
    DOWNLOAD_EXTRACT_TIMESTAMP option with a value of true to avoid this
    robustness issue.

Is there a version mismatch with llvm ? I didn't test with llvm-11 and llvm-12 though (not in the main ubuntu repository anymore).

@thedataking, might this have something to do with #1041?

[thedataking]

Not entirely sure what the problem is but it appears that the build is picking up files from both LLVM 14 and 15, e.g.:

/usr/lib/llvm-14/include/llvm/ADT/FoldingSet.h:258:29: error: redeclared with 1 template parameter

Can you try to explicitly set the LLVM version like this: LLVM_CONFIG_PATH=llvm-config-15 cargo install c2rust?

I just confirmed that if you install rustup and the c2rust prerequisites in a pristine ubuntu:23.04 docker image (cd /path/to/c2rust && docker run -it --rm --privileged -v $PWD:/opt/c2rust ubuntu:23.04 /bin/bash), c2rust builds correctly against LLVM 15.0.7.
