I would like to use kani, but it fails to build one of my dependencies (needletail), even though cargo build runs fine.
Step to reproduce:

git clone https://github.com/onecodex/needletail
cd needletail
cargo build  # OK

However, kani fails to build:

cargo kani
# Kani Rust Verifier 0.57.0 (cargo plugin)
# [...]
# error: linking with `cc` failed: exit status: 1
#  = note: rust-lld: error: version script assignment of 'global' to symbol 'bz_internal_error' failed: symbol not defined
          collect2: error: ld returned 1 exit
# error: could not compile `needletail` (lib) due to 1 previous error
# error: Failed to execute cargo (exit status: 101). Found 1 compilation errors.

Note: when I remove bzip2 from the dependencies of needletail, kani works fine, but I don't need to do it for cargo build.

Is there a difference in linking between cargo build and cargo kani?

Would you mind sharing:

  • Your setup (what OS/architecture you're running on)
  • The result of running cargo kani --debug

so we can try to dig into this problem? Thanks!

Hi @carolynzech,
I am using amd64/Debian 12. I reproduced the bug with a Debian virtual machine (after installing packages git curl build-essential).
I installed kani with:

cargo install --locked kani-verifier
cargo kani setup

Here is the output of cargo kani --debug on my (non virtual) machine. Do you need any other information?
