This is how I successfully installed haskelldb-0.10 package with ghc-6.8.2 today: Assuming you have downloaded and unpacked haskelldb-0.10 from http://hackage.haskell.org/packages/archive/haskelldb/0.10/haskelldb-0.10.ta... you need to append in haskelldb-0.10/haskelldb.cabal pretty, old-time, directory, old-locale in line build-depends: haskell98, base, mtl and -fglasgow-exts in line ghc-options: -O2 with that it should work: runghc Setup.hs configure runghc Setup.hs build runghc Setup.hs install manu-30 wrote:
Hello,
I'm trying to do something that should be fairly simple, installing some DB package so I can use MySQL or SQLite.
However I've had troubles building HSQL, HaskellDB and Takusen before giving up (I am using ghc 6.8.1 and Cabal-1.2.2.0).
------------------
with HSQL :
Database/HSQL.hsc:66:7: Could not find module `System.Time': it is a member of package old-time-1.0.0.0, which is hidden
so I added 'old-time' to the 'build-depends' line in the .cabal file
but then it fails building with
Building hsql-1.7... [1 of 2] Compiling Database.HSQL.Types ( Database/HSQL/Types.hs, dist/ build/Database/HSQL/Types.o )
Database/HSQL/Types.hs:134:18: Not in scope: type variable `forall'
Database/HSQL/Types.hs:134:25: Not in scope: type variable `a'
Database/HSQL/Types.hs:134:27: Illegal operator `.' in type `forall a . (Int -> FieldDef -> (FieldDef -> CString -> Int -> IO a) -> IO a)' (Use -XTypeOperators to allow operators in types)
etc...
At this point, it goes over my head...
---------------
What the hell, I'll use HaskellDB and FlatDB, but then I get this message while building HaskellDB :
src/Database/HaskellDB/HDBRec.hs:106:11: Illegal signature in pattern: l f a Use -XPatternSignatures to permit it
when I add 'PatternSignatures' to the 'Extensions:' line in .cabal, it fails configuring with :
Setup.hs: haskelldb.cabal:8: Parse of field 'extensions' failed:
Jeeeesus, nevermind, I'll try Takusen
---------------
with Takusen :
$ runhaskell Setup.hs configure
Setup.hs:26:7: Could not find module `Distribution.Program': Use -v to see a list of the files searched for.
I give up...
----------------
Is there any simple way to do it though ? Is there any problems with Cabal that I need to work around ?
Help !!
