[Haskell-iPhone] More arm-apple-darwin10-ghc trouble

Thu Jan 2 19:41:22 UTC 2014

I'm back at it after the holidays. I hope you all had a great New Years eve
and day! I got my program up and running with only one warning, which
doesn't seem like a big deal:

    (Apple Mach-O Linker Warning): PIE disabled. Absolute addressing
(perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in
_s3rt_info from /Users/schell/Code/blocks-ios/Blocks/src/Main.a(Main.o). To
fix this warning, don't compile with -mdynamic-no-pic or link with
-Wl,-no_pie

I just wanted to say thanks for your help!
