I'm trying to install and build Swift Compiler project to contribute to it, following this guide: https://github.com/apple/swift/blob/master/docs/HowToGuides/GettingStarted.md#system-requirements
When I run: sccache --start-server
it gives me an error, attached is an imaged showing the error message:
Install ccache using apt and use that wherever the guide says sccache. (They're very similar programs.)
Skip the parts related to sccache (such as the commandline arguments like --cmake-c-launcher). This may make repeated builds slower, but things should still work.
