The configure script takes a number of flags. The most commonly used is the --prefix=*/path/to/install/in* flag, which tells the bundle that you want it to be installed in */path/to/install/in* rather than the default location (/usr/local). To see all the flags that configure accepts, run configure --help. > > Any search for "running GHC versions in parallel only returned results > for the DPH extensions wiki but not how to run two GHC versions on the > same OS. > > http://www.haskell.org/haskellwiki/GHC/Data_Parallel_Haskell > > http://www.haskell.org/haskellwiki/Parallel > > > So any feedback welcome > > Rgds Gottfried > > _______________________________________________ > Haskell-Cafe mailing list > Haskell-Cafe@haskell.org > http://www.haskell.org/mailman/listinfo/haskell-cafe > > Mukesh Tiwari
