TL;DR: Needs one GHC patch and one base patch, has to use integer-simple, and make install still does not work. Otherwise works fine.
So, there it is. I will try with arm-unknown-nto-qnx8.0.0 (uses LLVM) next.
Start with a pristine GHC checkout. Apply the QNX patch to GHC< and the CLK_TCK patch to base. Set up as in the wiki page, and also use integer-simple (see previous email). ./configure --target=arm-unknown-nto-qnx8.0.0eabi --prefix="${QNX_HOST}/usr" This eventually results in: /tmp/ghc5601_0/ghc5601_0.bc:1085:0: Error: bad instruction `addl $28,%esp' /tmp/ghc5601_0/ghc5601_0.bc:1086:0: Error: bad instruction `ret' /tmp/ghc5601_0/ghc5601_0.bc:1090:0: Error: unrecognized symbol type "" make[1]: *** [libraries/ghc-prim/dist-install/build/GHC/Types.o] Error 1 make: *** [all] Error 2 And much similar output. This is because during cross-compiling, the triple is not passed through to LLVM, so LLVM assumes it is compiling for native. I have mentioned this before, but have now filed it as http://hackage.haskell.org/trac/ghc/ticket/7608. Apply the following as a hack: diff --git a/compiler/main/DriverPipeline.hs b/compiler/main/DriverPipeline.hs index 9e8556f..bcc1aa9 100644 --- a/compiler/main/DriverPipeline.hs +++ b/compiler/main/DriverPipeline.hs @@ -1393,7 +1393,8 @@ runPhase LlvmOpt input_fn dflags liftIO $ SysTools.runLlvmOpt dflags ([ SysTools.FileOption "" input_fn, SysTools.Option "-o", - SysTools.FileOption "" output_fn] + SysTools.FileOption "" output_fn + , SysTools.Option "-mtriple=arm-unknown-nto-qnx8.0.0eabi"] ++ optFlag ++ [SysTools.Option tbaa] ++ map SysTools.Option lo_opts) I then hit http://hackage.haskell.org/trac/ghc/ticket/7490, which is expected. Type make again to continue. By the way, lots of: when making flags consistent: Warning: No native code generator, so using LLVM I assume there's some sort of option I can set so that it expects this.
