| # In our experiments while building this action script, the Ubuntu 22.04 build was failing with | |
| # the compiler indicating that it wanted the libraries to be built with `-fPIE` while it was | |
| # trying to link the Rust project. This was remedied by adding the `Position Independent Code` | |
| # directive during CBMC build time. It's worth mentioning that this wasn't observed on our | |
| # local experiments on the same platform, but it seems to be doing no harm to the build overall | |
| # and allows us to test the Rust API on Linux without issues. | |
