Yes, exactly. Sorry for my bad phrasing. >>> The problem is not the size, but the size ratio. >> >> Ah, I see. Yes, my executables are a similar size.

Is there a chance to get it working for cross platform? There must be a lot of unused code in the exectuable. Is there no way to remove it? 5 Mb is rather large for an android app. > Incidentally, I now have a registerised cross-compiler for Raspberry Pi > compiling a working hello world :) (LLVM 3.0, GHC HEAD) > > GhcStage2HcOpts = -O0 -fllvm -pgmlc llc-3.0 -pgmlo opt-3.0 -optlc > -mtriple=arm-linux-gnueabihf -optlc -mattr=+vfp2 -optlc -float-abi=hard > GhcLibHcOpts = -O -fllvm -pgmlc llc-3.0 -pgmlo opt-3.0 -optlc > -mtriple=arm-linux-gnueabihf -optlc -mattr=+vfp2 -optlc -float-abi=hard > GhcRtsHcOpts += -fllvm -pgmlc llc-3.0 -pgmlo opt-3.0 -optlc > -mtriple=arm-linux-gnueabihf -optlc -mattr=+vfp2 -optlc -float-abi=hard > > Nice work everyone.
