Since it's a Solaris binary not a Linux binary it would need to be run on a Solaris host. If I run the following script to configure and run my cross-build: {{{ #!/bin/bash export TARGET=x86_64-sun-solaris2.11 export PREFIX=$HOME/Documents/gcc/cross/$TARGET export SYSROOT=$PREFIX/sysroot export PATH=$PATH:$PREFIX/bin export GCC=$PREFIX/bin/$TARGET-gcc export LD=$PREFIX/bin/$TARGET-ld export NM=$PREFIX/bin/$TARGET-nm export OBJDUMP=$PREFIX/bin/$TARGET-objdump # cabal install happy alex haddock # sudo apt-get update # sudo apt-get install --assume-yes ghc libncurses5-dev \ # mesa-common-dev freeglut3-dev libedit-dev git clone git://github.com/ghc/ghc pushd ghc echo "Stage1Only = YES" >> mk/build.mk cp mk/build.mk{.sample,} ./sync-all --no-dph get perl boot patch -d libraries/haskeline/ -p1 < \ ../ghc-patches/0001-Include-termios.h-for- solaris2-host.-Fixes-8366.patch cp $SYSROOT/opt/local/include/gmp.h libraries/integer-gmp/gmp/ ./configure \ --host=x86_64-unknown-linux-gnu \ --build=x86_64-unknown-linux-gnu \ --target=x86_64-sun-solaris2 \ --with-gcc=$GCC \ --with-ld=$LD \ --with-nm=$NM \ --with-objdump=$OBJDUMP make }}} I get the following failure output: {{{ ~/Documents/ghc ~/Documents patching file System/Console/Haskeline/Backend/Posix.hsc Reversed (or previously applied) patch detected!

This forces the result to have at least the constraints of join, which in my case is "IxMonad m". {{{#!hs {-# LANGUAGE RebindableSyntax, ApplicativeDo #-} module My where -- straightforward definitions of fmap, pure, (<*>), join, return, (>>=), (>>) and fail in terms of IxFunctor, IxPointed, IxApplicative, IxMonad fPure m = do a <- m b <- m pure (a, b) fReturn m = do a <- m b <- m return (a, b) }}} According to -ddump-ds, these desugar to: {{{#!hs fPure :: IxMonad m => m k1 k1 a -> m k1 k1 (a, a) fPure m = My.join ( My.(<*>) (My.fmap (\a b -> My.pure (a, b)) m) m ) fReturn :: IxMonad m => m k1 k1 a -> m k1 k1 (a, a) fReturn m = My.join ( My.(<*>) (My.fmap (\a b -> My.return (a, b)) m) m ) }}} But I would expect: {{{#!hs fPure m = My.(<*>) (My.fmap (\a b -> (a, b)) m) m fReturn m = -- same }}} It appears that when "return" is not from base, ApplicativeDo only partially desugars to the specification. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/12490> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I've reproduced the problem on Mac and Linux with GHC 8.0.1, didn't try on Windows. The root of the problem seems to be an interaction with template haskell and the recompilation manager. I'll now explain the setup. I've attached an archive which contains all code and a simple build script. Just unpack the archive and execute ./build.sh to reproduce the problem. The setup consists of four files. (Don't be confused by the module names. They are derived from our project). The problem arises after a change to one of these files and a recompilation. Here are the initial versions of the four files. {{{#!hs -- src/ShortText.hs module ShortText where data ShortText = ShortText String toString :: ShortText -> String toString (ShortText s) = s }}} {{{#!hs -- src/Hospital.hs module Hospital where foo :: Int -> String foo i = show i }}} {{{#!hs -- src/Types.hs {-# LANGUAGE TemplateHaskell #-} module Types where import qualified Hospital import Language.Haskell.TH genCode :: Q [Dec] genCode = let s = Hospital.foo 5 in [d|string = s|] }}} {{{#!hs -- src/MetaHandler.hs {-# LANGUAGE TemplateHaskell #-} module Main where import qualified Types -- splices in "string :: String" $(Types.genCode) main :: IO () main = putStrLn string }}} Compiling the project for the first time works without problems: {{{ $ /Users/swehr/.stack/programs/x86_64-osx/ghc-8.0.1/bin/ghc -O0 -isrc -ibuild -dynamic -outputdir build -package template-haskell --make src/MetaHandler.hs [1 of 3] Compiling Hospital ( src/Hospital.hs, build/Hospital.o ) [2 of 3] Compiling Types ( src/Types.hs, build/Types.o ) [3 of 3] Compiling Main ( src/MetaHandler.hs, build/Main.o ) Linking src/MetaHandler ... }}} I then changed the content of src/Hospital.hs to use the ShortText module.
