darcs 1.0.9 fails to configure due to incompatibility with ghc 6.8.2

[ndimiduk@…]

ghc-6.8.2 installs without issue but contains an API incompatible with darcs-1.0.9. Here's the output:

Here's a link to a mailing list entry which looks directly relevant: http://www.mail-archive.com/darcs-devel@darcs.net/msg04019.html

I've created a Portfile for darcs-2.0.0pre3 (see #14634), which seems to work with ghc-6.8.2.

Assigning to maintainer.

[shreevatsa.public@…]

cc me, I'd like to use darcs too. (Does posting a comment on Trac automatically add a user to the cc yet?)

[stephen.bannasch@…]

I get the same error on MacOS 10.5.2.

I updated ports before trying to run the install:

sudo port selfupdate
sudo port upgrade installed

How can I add myself to the CC list? hmm ...

Sorry, not possible as Trac does not allow so fine-grained permissions. Just ask to get added.

seems to be incompatibility of the new GHC.Handle.openFd (change in the API), and the debian folks have a workaround patch. See for example

I tried applying that patch but darcs is still not compiling.

[gwright@…]

The most recent versions of ghc (6.10.1) and darcs (2.1.2) do not have this incompatibility.
