Hi Libraries ;-) I have ghc-6.10.4 and many libraries installed and everything works nicely. I'd like to upgrade my Cabal + cabal-install so I can use the new features (especially the improved support for library plus executables in one package). Is this safe? I mean, do I have to fear my installation breaks if I install Cabal-1.8.0.4? I have discovered problems when upgrading Cabal in the past but this is quite some time ago. Also, I am confused by the output of cabal-install regarding such an upgrade: ben@sarun[2]: ~ > cabal --version cabal-install version 0.6.4 using version 1.6.0.3 of the Cabal library ben@sarun[2]: ~ > cabal install cabal-install --dry-run Resolving dependencies... In order, the following would be installed (use -v for more details): cabal-install-0.6.4 ben@sarun[2]: ~ > cabal install Cabal --dry-run Resolving dependencies... In order, the following would be installed (use -v for more details): Cabal-1.8.0.4 ben@sarun[2]: ~ > cabal list cabal-install * cabal-install Synopsis: The command-line interface for Cabal and Hackage. Latest version available: 0.8.2 Latest version installed: [ Not installed ] Homepage: http://www.haskell.org/cabal/ License: BSD3 So, cabal-install would upgrade Cabal from 1.6.0.3 to 1.8.0.4, but not itself from 0.6.4 to 0.8.2. I used the -v option but it did not make clear to me which dependencies of 0.8.2 conflict with what I have installed. And maybe there is no conflict, since ben@sarun[2]: ~ > cabal install cabal-install-0.8.2 --dry-run Resolving dependencies... In order, the following would be installed (use -v for more details): Cabal-1.8.0.4 cabal-install-0.8.2 When I give cabal-install an explicit version number for the package to install, does this somehow circumvent safety measures? Thanks Ben
