#7152 new feature request

Add flag to configure that skips overwriting of symlinks on install

Sometimes when I'm installing a GHC release candidates I'd like to install the RC without overwriting the ghc etc symlinks in /usr/local/bin. It would be convenient to have a configure flag that told the install step to only install the versioned binaries (e.g. ghc-6.2.1) in /usr/local/bin, without the symlinks.

I like this idea too.

I install different versions to /usr/local/ghc/ghc-x.y.z and have a bunch of bash functions/aliases that prepend the selected version to $PATH &c.

If we're going to allow multiple versioned binaries to be installed directly to /usr (which would be nice), we'll want some way to choose between them too, cf. gcc_select on OS X, in which case we should also figure out how that'd interact with say Debian's update-alternatives(8).

I'll look into this for 7.8.1. I agree we should maybe have some gcc_select style thing, but I don't quite know how these works or the details of Debian's approach, so I may just do the simple thing first and come back to that.

  • Milestone changed from 7.8.3 to 7.10.1

Bumping priority down (these tickets haven't been closely followed or fixed in 7.4), and moving out to 7.10 and out of 7.8.3.

Actually dropping priority. :)

Moving to 7.12.1 milestone; if you feel this is an error and should be addressed sooner, please move it back to the 7.10.1 milestone.
