Thank you for your contribution!

Our team primarily uses Ubuntu 20.04 LTS for development. We need to conduct further testing with this environment to ensure compatibility. Once the tests are successful, we will proceed with merging your pull request.

Thank you for your understanding and patience.

This will cause build failures for iEDA on Ubuntu 22.04 or older versions, as the glog version on these Ubuntu releases is 0.4.0 (or 0.5.0), which requires the size type to be declared as int.
