Do I understand you right, that Clang's CPP converts spaces into tabs? :-/
So this is what I thought 3 hours ago, I'm not so certain anymore. I'm trying to build happy (from git, 2cfc3b70cd from https://github.com/simonmar/happy) If I run: {{{ ghc-7.6.3 -E -cpp templates/GenericTemplate.hs -DHAPPY_ARRAY }}} Then it has no tabs. But when I use cabal install instead, the file: {{{ dist/build/happy/happy-tmp/AttrGrammerParser.hs }}} contains tabs. cabal builds it with: {{{ '/usr/local/bin/clang-xcode5-wrapper' '-E' '-undef' '-traditional' '-m64' '-fno-stack-protector' '-m64' '-I' 'dist/build/happy/happy-tmp' '-I' 'dist/build/happy/happy-tmp' '-I' 'dist/build/autogen' '-I' 'dist/build/happy/happy-tmp' '-I' '/usr/local/Cellar/ghc/7.6.3/lib/ghc-7.6.3/base-4.6.0.1/include' '-I' '/usr/local/Cellar/ghc/7.6.3/lib/ghc-7.6.3/include' '-D__GLASGOW_HASKELL__=706' '-Ddarwin_BUILD_OS=1' '-Dx86_64_BUILD_ARCH=1' '-Ddarwin_HOST_OS=1' '-Dx86_64_HOST_ARCH=1' '-U __PIC__' '-D__PIC__' '-include' 'dist/build/autogen/cabal_macros.h' '-x' 'c' 'dist/build/happy /happy-tmp/AttrGrammarParser.hs' '-o' '/var/folders/4q/5j7w6x5x3c1bc427tcgvg4sc0000gn/T/ghc10733_0/ghc10733_6.hscpp' }}} where the wrapper is: https://github.com/ghc-ios/ghc-ios- scripts/blob/master/clang-xcode5-wrapper.hs -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8493#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
