Attempting to install the irony server through M-x irony-install server returns the following

My Cmake version is 3.14.6 My emacs version is 26.2

Not sure if it helps, but I'm running Gentoo Linux.

does it work better if you rm -r /tmp/build-irony-server-1.3.1/, and then try the install again?

Yes, thank you very much. Apparently the error occurred when another user installed the irony server on their user, and the files in /tmp had not been deleted yet.

Right, maybe the temporary folder should be created per-user.

+1. While I don't imagine Windows or MacOS implement $XDG_CACHE_HOME (usually $HOME/.cache/name-of-application) that's the location I'd generally expect to be used, and AFAIK ~/.emacs.d wouldn't be the right place.

@Sarcasm, it would also be nice to see this issue resolved in the next tagged version ;-)
