I fixed my earlier problems with compiling primitive and vector by re-compiling ghc-iphone HEAD. It seems now that I can use arm/i386-apple-darwin10/11-cabal to build a static lib, but when I try to link it in my Xcode project I get ld warnings: ld: warning: ignoring file /Users/schell/Code/blocks-ios/Blocks/dist-arm/build/Blocks/Blocks.a, file was built for archive which is not the architecture being linked (i386): /Users/schell/Code/blocks-ios/Blocks/dist-arm/build/Blocks/Blocks.a I get one of those for each architecture being built (armv7, armv7s, arm64, i386). Here are some details on my setup: https://gist.github.com/schell/f3a737171ce2f6b1119c Any help would be much appreciated! :) -- Schell Scivally http://blog.efnx.com http://github.com/schell http://twitter.com/schellsan
