Cannot build on Ubuntu 20.04

[rothgar]

The make target is looking for gcc-5 which is really old and not available on Ubuntu 20.04. I saw a PR #47 to update it but that has been open for almost a year. Are there any plans to update the build tooling so this tool can continue to be used?

Hi, @rothgar!
Could you please share the errors you are seeing?

I am able to build on Ubuntu 20.04 with Go 1.15:
