The ghcup command in the README does not work with ghcup 0.1.19.0 #20

Closed Kleidukos closed 1 year ago

ghcup install ghc -p x86_64-deb10-linux 8.10.7 returns an error:

Invalid argument `8.10.7'

Hm, it seems ghcup doesn't take the -p flag anymore. This was necessary for a couple of GHC versions (that were built with Fedora 33, it seems) if the host OS was Arch, because the Fedora bindists it downloaded then were not compatible with the Ubuntu sandbox OS.

The only thing I see in the ghcup user guide now is this, which is I guess a possibility but more heavyweight than I would like. @hasufell Am I missing something, or was there a particular reason to remove the -p flag to ghcup install ghc?

P flag still exists, but comes after ghcup directly: ghcup -p <triple> install ghc.
