Can't build darcs with ghc-6.6

[steve@…]

Firstly - thanks for the great work!

I noticed that the ghc port was finally buildable on my intel mac, so I installed it and then tried to build darcs.

Sadly, the darcs build failed. I understand that darcs is buildable with GHC 6.6, but I guess that darcs 1.0.8 is not. Must we wait for a new darcs release, or can the darcs port build from the ghc-6.6 branch of darcs?

Failure messages follow:

Just for fun, I tried compiling darcs-1.0.9rc1 with the macports ghc-6.6. It gets further, but fails at the linking stage:

Try adding --make to ghc switches in the makefile, that'll pick up the library depencies correctly.

[jon.olsson@…]

Patch 1 needed for GHC 6.6 build

[jon.olsson@…]

Patch 2 needed with GHC 6.6

[jon.olsson@…]

Portfile diff to include the two patches

[jon.olsson@…]

And this patch is also needed:

Cc maintainer.

[gwright@…]

Should be fixed. I dropped the priority from Blocker -> Important. Blocker means that the problem affects many ports. "Important" should be used for ports that don't build.

Give it a try and if it works for others I'll close the bug.

[ryan@…]

The patches work for me...this should probably be closed.

[gwright@…]

Thanks for giving it a try. I'm closing this bug.
