Hi,
I have a question about ghc-6.2 and template haskell on Mac OS X. I think
it's a ghc configuration or build issue, so I'm posting here instead of the TH list.
I have ghc-6.2 built under darwinports. This uses a 6.0.1 binary to bootstrap the
6.2 build. I haven't updated the binary bootstrap compiler because it seems
to work under both Jaguar (10.2.x) and Panther (10.3.x). The portfile builds ghc-6.2
with the command 'make all'. The resulting ghc-6.2 has worked fine until I tried to
build a program using TH. I tried to build the simplest example--the one in the
User's guide-- and it failed with:
> ghc --make -fth main.hs -o main Chasing modules from: main.hs Compiling Printf ( ./Printf.hs, ./Printf.o )
./Printf.hs:23: Type constructor or class not in scope: `Expr'
./Printf.hs:26: Variable not in scope: `string'
./Printf.hs:30: Type constructor or class not in scope: `Expr' >
This must be a simple problem. The other thing to note about the darwinports
build is that it stages the installation into a temporary directory so it can do an
inventory of the files that will be installed. If a path in the staging directory gets
compiled in, instead of the final installation directory, all manner of unhappiness
can result.
Any one have any ideas? The answer is probably staring me in the face but
I'm not able to see it.
Best Wishes,
Greg
