I tried to build whisperfish with the SDKs Docker based build engine, but I ran into a problem that seems to be fixed in a newer version of
cargo. Now, I would like to try a newer version of
rust to build whisperfish, but I couldn’t find a way to get these into the docker build engine. I think the
sfdk tools install-custom (forgive me if I mixed up the sub-command word order, but I am currently not on a system with
sfdk, so I can't look it up) could be used to install custom build tools, but the documentation doesn’t really show how. Do I need RPMs to install the tools?
