'backslash' build problems on windows
by Twan van Laarhoven 16 Jan '08

16 Jan '08

I am having some problems with the latest builds of GHC on windows. For some reason ghc has decided to use backslashes in filenames. This leads to problems when building the stage libraries and the stage 2 compiler. I run the scripts from a mingw bash shell. The following problems occur: - Warnings: .../ghc3228_0/ghc3228_0.lpp:1: warning: unknown escape sequence '\B' these are caused by the #line directive in the preprocessed file, something like #line 1 ".\basicTypes/BasicTypes.lhs" - When building the dependencies (in dist/build/.depend) become something like: dist/build\GHC/PrimopWrappers.o : .\GHC/PrimopWrappers.hs make then ignores these dependencies and tries to build the wrong files. - When testing, some unexpected failures occur, because the error message says ".\Something.hs" instead of "Something.hs". The solution to all these problems is to use a '/' instead of a '\'. I suspect the problem was caused by the patch: Sat Jan 12 18:28:37 W. Europe Standard Time 2008 Ian Lynagh * FilePath fixes Twan

GHC Internals Changed
by C.M.Brown 14 Jan '08

14 Jan '08

Hi, It seems that GHC's API interface has changed between 6.6 and 6.8. Most notably, JustTypecheck and GHC.dropForAlls are no longer in scope. Are the changes documented anywhere? The notes on the hackage commentary still seem to point to the previous API internals. http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/API Kind regards, Chris.

`show' in ghci dialogue
by Serge D. Mechveliani 12 Jan '08

12 Jan '08

People, I have a question about usage of `show' in the GHCi dialogue system. I introduce my user class DShow, trying to improve the class Show of Haskell-98. For example, I program --------------------------- class DShow a where dShow :: ShowOptions -> a -> String ... main = let listOfListPairs = [ ([1,2,3], [] ), ([4,5,6], [7] ), ([9,8,0], [0,0,0]) ] :: [ ([Int], [Int]) ] opts = ShowOptions {verbosity = 2, listSepator = ", \n\n", fieldSeparator = ", \n"} in putStr (dShow opts listOfListPairs) --------------------------- Then, the command ./Main outputs ----------------------- [([1, 2, 3], []), ([4, 5, 6], [7]), ([9, 8, 0], [0, 0, 0])] ----------------------- This way of the output format control by dShow and ShowOptions is my goal. But the command > main in the ghci interpreter outputs something like this: "[([1, 2, 3), []),\n\n([4, 5, 6), [7]),\n\n([9, 8, 0],\n\n[0, 0, 0])]" How can the user force ghci to output the same output format as in the case of ./Main (how to interprete '\n') ? 1. If we give to the interpreter the line > listOfListPairs , then the ghci dialogue system does interprete the NewLine characters on output as needed -- only for the value of (show listOfListPairs). And I need it for the value of (dShow opts listOfListPairs). Is there any way to substitute a user function instead of `show' in the ghci output? (and dShow has additional argument ...). 2. Which function outputs a string in the ghci dialogue system? Can the user make this function to interprete the NewLine character in the argument string? Thank you in advance for your explanation. ----------------- Serge Mechveliani mechvel(a)botik.ru

Any Debian Etch packages for GHC 6.8.2?
by Wagner Ferenc 11 Jan '08

11 Jan '08

Hi, speaking of binary dists, does anybody know of some Debian Etch packages of GHC 6.8.2? If nothing else is available, I'm ready to repackage a .tar.gz as a .deb, but I wonder if there's anything better available already... -- Thanks, Feri.

ghc 6.6.1 -optl bug?
by Bulat Ziganshin 11 Jan '08

11 Jan '08

Hello GHC, sorry, i'm still user of 6.6.1 version the following command: ghc --make .... -optl-s strips the executable while the following command ghc --make .... -optl--strip-all has no effect. i made some experiments and it seems that options starting with "--" are not sent to ld at all (you can write -optl--unexisting-option but not -optl-#) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
