Git build failure on Ubuntu 24.04 #1099

Closed jtesta closed 1 week ago

jtesta commented 1 week ago

On a fresh and fully updated Ubuntu 24.04 VM, building and installing directly from git fails.

I installed the documented prerequisites with:

$ sudo apt install build-essential llvm clang libclang-dev cmake libssl-dev pkg-config python3 git
$ sudo apt install cargo llvm-dev

Then I ran:

$ cargo install --git https://github.com/immunant/c2rust.git c2rust

I've attached the full output of the above command, as it is too long to include inline: ubuntu24_git_build_failure_output.txt

FYI, I dusted off an old Ubuntu 20.04 VM, and managed to successfully install c2rust with the above instructions.

Thanks for the detailed report. This kind of breakage happens after new versions of clang are released since we rely on internals of the clang AST. I don't have access to a ubuntu 24.04 box right now but I bet if you try with an older version, it will build correctly on 24.04. That is not to say that we don't need to fix this issue; we definitely should.

@jtesta can you try PR #1100 and let me know if it fixes the issue for you?

Yep, that works!:
