Error in cargo test: could not find canonical-backup.binproto

[anirbanc3]

Hi,

I have been trying to build libsignal on Ubuntu 22.04. cargo build completes successfully but getting a weird No such file or directory issue while executing cargo test

error: couldn't read rust/message-backup/tests/res/canonical-backup.binproto: No such file or directory (os error 2)
  --> rust/message-backup/tests/test_cases.rs:70:20
   |
70 |     let binproto = include_bytes!("res/canonical-backup.binproto");
   |                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: this error originates in the macro `include_bytes` (in Nightly builds, run with -Z macro-backtrace for more info)

error: could not compile `libsignal-message-backup` (test "test_cases") due to previous error
warning: build failed, waiting for other jobs to finish...

I could manually verify the file canonical-backup.binproto is present as symbolic link in the mentioned directory. I tried uninstalling and then reinstalling rust and cargo, but the error still persists. Any suggestions or leads to resolve this will be highly appreciated.

Don't forget to check out (and update) the Signal-Message-Backup-Tests submodule, that's where the symlink is pointing. (We should probably mention the submodule in our readme, thanks for the push.)

Thanks for the response. cargo test ran successfully after updating git submodule.
