Hi deech,

If I were you I would try to report the issue directly on c2hs issue tracker: https://github.com/haskell/c2hs/issues

The developer is very reactive there!

Cheers

Hi all, c2hs runs into the following error on all of my .chs files, but only on Windows: c:\\program files\\haskell platform\\2014.2.0.0\\mingw\\bin\\../lib/gcc/x86_64-w64-mingw32/4.6.3/../../../../x86_64-w64-mingw32/include/stddef.h:20: (column 11) [ERROR] >>> Syntax error ! The symbol `__attribute__' does not fit here.

My c2hs version is: C->Haskell Compiler, version 0.23.1 Snowbounder, 31 Oct 2014 build platform is "x86_64-mingw32" <1, True, True, 1>

This is the command being run: "c:\Users\deech\AppData\Roaming\cabal\bin\c2hs.exe" "--cpp=c:\Program Files\Haskell Platform\2014.2.0.0\mingw\bin\gcc.exe" "--cppopts=-E" "--cppopts=-D__GLASGOW_HASKELL__=708" "--cppopts=-Dmingw32_BUILD_OS=1" "--cppopts=-Dx86_64_BUILD_ARCH=1" "--cppopts=-Dmingw32_HOST_OS=1" "--cppopts=-Dx86_64_HOST_ARCH=1" "--cppopts=-I./c-src" "--cppopts=-I./" "--cppopts=-IC:/MinGW/include" "--cppopts=-IC:\Users\deech\Downloads\fltkhs-0.1.0.1/c-src" "--cppopts=-IC:\Users\deech\Downloads\fltkhs-0.1.0.1" "--include=dist\build" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\process-1.2.0.0\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\directory-1.2.1.0\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\time-1.4.2\include" "--cppopts=-IC:\ProgramFiles\Haskell Platform\2014.2.0.0\lib\Win32-2.3.0.2\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\bytestring-0.10.4.0\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\base-4.7.0.1\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib\integer-gmp-0.5.1.0\include" "--cppopts=-IC:\Program Files\Haskell Platform\2014.2.0.0\lib/include" "--output-dir=dist\build" "--output=Graphics\UI\FLTK\LowLevel\HorValueSlider.hs" "src\Graphics\UI\FLTK\LowLevel\HorValueSlider.chs"

A little Googling turned up this thread: http://haskell.1045720.n5.nabble.com/BUG-string-h-FC4-x86-64-td3196369.html which suggested I pass -D__attribute__(A)= to c2hs's opts. I tried it and it led to other errors. I didn't pursue any further because it's an old thread. I'm not sure what stddef.h is and I'm unfamiliar with Windows.

Any help is appreciated. Thanks! -deech
