Hi.

After doing whatever it wants to do, successfully (at least that's what I think the logs say; I didn't notice any error) I update my path to: export PATH=/home/.../.cabal/bin:$PATH

Everything is "OK" now! But I still don't have a cabal-install binary, and this update has been performed only for me (inside my user account)!

Shouldn't I have a binary cabal-install to run?

The binary is called "cabal", not "cabal-install". You should be able to check whether the new version is being used by saying "cabal --version".

How can I update globally? (for all users of the system!)

By saying something like "sudo cabal install --global cabal-install".

Incidentally, it's better to say cabal install --root-cmd=sudo --global cabal-install That way, cabal will only acquire root privileges for the installation. It does not need to run as root for the entire downloading, building, etc. process, and in fact doing so can be bad, since it pollutes your package cache with files owned by root, leading to potential permissions problems in the future. -Brent

Oh my. This is some long magical incantation. Is this documented somewhere? At least in the cabal faq? -- Kim-Ee

Probably not since it's strongly disrecommended to do global installs. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
