ghc will not build on Lion

[bowman@…]

On OSX Lion, using XCode 4.2 and a fresh install of macports I am unable to build ghc.

Here is what I take to be the relevant portion of the build log:

:info:configure checking for ld... /usr/bin/ld
:info:configure checking for path to top of build tree... ghc: could not execute: /usr/bin/gcc-4.2

configure complains that gcc-4.2 is not installed. Of course gcc-4.2 will not build on Lion, so I'm not sure if a symlink is supposed to be in place of what.

Hopefully r86459 fixes this. Wait 30 minutes, "sudo port selfupdate", "sudo port clean ghc" and try again.

Thank you, that addresses the problem above. Now the build fails a bit further on. Here's the relevant excerpt from the log:

second main.log

[ryandesign (Ryan Carsten Schmidt)]

Ok, I don't know what to do about that. Reassigning to maintainer.

P.S: Don't forget to use WikiFormatting.

It builds for me now. If someone can confirm maybe the ticket can be closed.

So... not broken anymore after all then?

[info@…]

don't know what caused the error two days ago, but ghc is now installed

[amarqueslee@…]

Cc Me!

[amarqueslee@…]

Not sure if this should be here or in a new ticket.

ghc installs from me, but won't compile anything:

$ ghc hello.hs
ghc: could not execute: /usr/bin/gcc-4.2

Somewhere it's still being configured to point to the wrong gcc.

I tried giving it the right version of gcc with

-pgmc `which gcc`

but ghc still seems to not be able to find my gcc.

Thanks in advance for the help!

[amarqueslee@…]

Can't believe I didn't think of this immediately, but a pseudo-fix is:

cd /usr/bin
sudo ln -s gcc gcc-4.2
#enter password

Ghc now compiles, but ld warns about a couple of invalid flags and things being passed through when ghc links... I get the feeling undefined behaviour will come back and bite me for this when i least expect it...

Port abandoned, #35561.

[neverpanic (Clemens Lang)]

Since the Lion buildbot has successfully built ghc (see ​http://packages.macports.org/ghc/) I think this is obsolete. Please re-open if the problem still persists.
