Hi again. Ok, we migrated our modifications to 6.6.1, compiled it on the ia64 architecture and it worked :). Ian, thank you very much for your help. Currently we're experiencing another problem: we are not able to use -Nx option even though we compile our program with -threaded option. Find the log at the end of this message (notice that -N doesn't appear as one RTS available option). Thank you very much in advance for the replies. Regards. Cristian Perfumo

We've been trying to compile GHC 6.6 on ia64, and although we have applied the patch on http://hackage.haskell.org/trac/ghc/ticket/1150 , we still get some mangler errors with "nop 0"s.

As well as the patch attached to that bug report, there were a couple more patches for IA64 that went in recently. All the patches are in 6.6.1, so you might have more luck with that.

Thanks Ian
