Re: [Haskell-cafe] __GLASGOW_HASKELL__ macro in 7.2.1

2011-10-14 Thread JP Moresmau 
Thank you both, I misread that page on the versions and didn't see the
difference between minor version number and release number. So I can
confirm, my 7.0.3 install gives me 700 and my 7.2.1 gives me 702.
Everything is good. Thanks!

No, __GLASGOW_HASKELL__ == 702 means you're using ghc-7.2.*, not 7.0.2.

The second and third digit of the version are for the second component, so 
610 was 6.10.*, 612 was 6.12.*

#in __GLASGOW_HASKELL__ >= 702
-- code for 7.2.1 and greater
#else
-- code for ghc <= 7.0.4
#endif

Nothing stupid, you're just misinterpreting the value of
__GLASGOW_HASKELL__. See:
http://www.haskell.org/ghc/docs/latest/html/users_guide/version-numbering.html
for the correct interpretation.

[Haskell-cafe] __GLASGOW_HASKELL__ macro in 7.2.1

2011-10-14 Thread JP Moresmau 
Hello list,
I must be doing something stupid, but what?

ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.2.1

ghc -E -optP-dM -cpp Main.hs (per
http://www.haskell.org/ghc/docs/latest/html/users_guide/options-phases.html)

{-# LINE 1 "Main.hs" #-}
#define mingw32_HOST_OS 1
#define i386_BUILD_ARCH 1
#define __GLASGOW_HASKELL__ 702
#define __STDC_HOSTED__ 1
#define i386_HOST_ARCH 1
#define mingw32_BUILD_OS 1

I'm on Windows so everything else is correct except the line that
tells me I'm using 7.0.2.
Unfortunately I have code that works under 7.0.3 and breaks under
7.2.1 (and the 7.2.1 code breaks under 7.0.3, of course) so I don't
see anything other option than conditional compilation.

What am I doing wrong?

Thanks!
