Why source_sink 'library(tipc/tipc)' does not exist?

After all, it seems that TIPC is indeed available on Linux only. It is documented, see here. Look for “compatibility”.

Jan said the same but the topic got split off so you probably didn’t see it.

I don’t know if you want to report the other test errors that you see. It could be caused by incorrectly installed dependencies, or maybe there are real problems.

PS: if tipc is not available on MacOS for sure, it should be removed from the Homebrew scripts I guess? @jan? I do not have a Mac at all so I don’t even know where to start.

PPS: The code for the Homebrew formula is here I guess? There isn’t a documented flag for not trying to install TIPC, but in CMAKE.md I read:

Note that packages for which the prerequisites cannot be found are dropped automatically, as are packages for which the sources are not installed.
