[Haskell-cafe] compiling GHC 7.8 on raspberry pi

Greetings, I'm trying to get a haskell program to run on a raspberry pi (running raspbian). Unfortunately it requires template haskell. Since the GHC included in raspbian wheezy doesn't support TH I'm trying to compile GHC 7.8.4 on the rpi. Most of the compilation worked fine. I got problems with the memory consumption, but adding a lot of swapspace solved this problem. During the final phase the compilation process complains about a "strange closure type 49200" (the exact number is varying, but most often it's 49200). Does anyone here have experience, how to compile GHC 7.8 on a raspberry pi? As a side note: The compilation is running in QEMU while the compiled program should run on a real rpi. Regards Sven
