Re: [Haskell-cafe] package question/problem
Hi Vasili, have a look at all options of ghc-pkg. There is one command to hide a package. Hidden packages will be shown by ghc-pkg list in parenthesis. The second way to hide packages is passing a special option to ghc (you can look it up in the ghc documentation or by running ./setup build -v3). Probably here it's another reason: Maybe the build-depends fields of the package are wrong. So just open the .cabal file and add it. pay attention to if flag(...) build-depends : else build-depends : so that you add it to the right one. >What is the history of old-time package? Hmm. It's superseded by the new time library found on hackage.. I hope that this message will help you.

The exception was: > exit: ExitFailure 1 > [EMAIL PROTECTED]:~$ This happens because Cabal invokes ghc with the -hide-all-packages flag. It then adds explicit -package flags for all packages listed as build dependencies. (The idea is to force developers to specify all their package's dependencies in the library's .cabal file.) Sadly, hsql looks unmaintained. You can try unpacking the hsql-1.7 tarball and adding the required dependencies to the build-depends: field of the .cabal file. Running 'cabal install' in the source directory will attempt to install the package. > What is the history of old-time package? old-time was split out of the base package in base 3.0 (which ships with ghc 6.8.x).

The simple answer is that the package is unmaintained and has not been updated to work with ghc 6.8.x. You can either use HDBC instead or fix HSQL by applying one of the patches floating around or fix it by following Bertram or Marc's advice.

Hi Duncan, I was under the impression that HDBC doesn't support myqsl??

You can connect HDBC to MySQL using the HDBC-ODBC backend, see http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HDBC-odbc.

But perhaps you can persuade Frederik Eaton to make new working releases of HSQL. Duncan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
