RPM doesn't support --prefix

[skaller]

After installing ghc for linux using rpm with
--prefix=/usr/local,
the ghc scriipt incorrectly thinks the libraries etc
are in /usr:

#!/bin/sh
GHCBIN="/usr/lib/ghc-6.2.2/ghc-6.2.2";
TOPDIROPT="-B/usr/lib/ghc-6.2.2";
# Mini-driver for GHC
exec $GHCBIN $TOPDIROPT ${1+"$@"}

After editing, at least the compiler actually starts up :)

You're trying to install the binary RPM using a different
prefix?  That's not supported, I'm afraid.

I can see it isn't supported :)

However after the change to those two lines, the compiler
works, links libraries, and the resultant binary executes
correctly
(as far as I can tell never having written any Haskell
before .. :)

So why not support it? I had no choice .. my root partition,
containing /usr is 97% full.. :)

Re-opened.  Any RPM gurus out there who could knock this one
on the head?

Note it's not just the ghc script, there's a couple of other
scripts that need munging (ghci, ghc-pkg, hsc2hs maybe).

Still a problem with 6.2.4 - Additionally, you now need to
edit the package.conf file.

Not really sure what the right solution is - one hack that
comes to mind is adding a %post install script in the spec file
that would replace the default prefix with the specified one.

This is now fixed in Fedora Haskell as of ghc-6.4-7.
I will send in a spec file patch "as soon as the dust settles".

Feel free to assign this to me. :)

What's the status of this?

[igloo]

We plan to change the build system to always work as if BIN_DIST was set, so the script would have $topdir in it rather than a fixed path. This would be substituted for at install time, so this bug should then be easily fixable.

We're not going to hold 6.6.1 up for it, but it should be easily doable for 6.6.2.

Sven, is anything happening regarding this bug? Do we intend to fix it?

fix CC

Bryan: this is an old bug against GHC. Is it worth keeping around, do you think?
