GHC 6.12

[Antoine Latter]

Folks,

Attached is a patch against happstack HEAD to compile against GHC
6.12. Most of it is just chasing down types until it builds. I have
also tested the patch against GHC 6.10, but it could surely use more.

A few areas to note:

- I don't have any projects using ixset, but I've included it for
completeness. It compiles, but I'm not certain the 'infer ixset' stuff
will work properly against type vars of higher kinds with kind
annotations.

- You'll need syb-with-class from darcs head if you want to test with GHC 6.12

- You'll need a version of GHC 6.12 newer that RC1 to test against 6.12

Also - is this the right place to send patches?

Take care,
Antoine

Excellent. I'll check that it also builds against 6.8 and then apply
it! Thanks!

And, yes, this is the right place to send patches.

Hello,

I applied this patch. But, we are having trouble getting happstack
dependencies to compile under 6.12. Did you encounter this error?


I encountered a problem with the compilation of happstack there: the
package strict-concurrency doesn't compile:
Building and installing all cabal packages
Resolving dependencies...
Configuring strict-concurrency-0.2.1...
Preprocessing library strict-concurrency-0.2.1...

thanks!

Attached is a patch against the strict-concurrency darcs repo which
fixes this. Also CC'ing the maintainer. I haven't tried this against
GHC 6.8, but the old library documentation for base seems to indicate
that this should work quite a bit further back than that.

Thank your dons and Antoine Latter!

Now we just need to get sendfile working on 6.8 and 6.12 and we are
looking really good!
