People,
can you, please, explain me how to make the `random' package visible for GHC ?
It is visible to GHC, but `cabal install random` installed the package into the user database:
and now ghc-pkg list shows
------------------------------------- /home/mechvel/ghc/7.8.2/inst0/lib/ghc-7.8.2/package.conf.d ...
/home/mechvel/.ghc/x86_64-linux-7.8.2/package.conf.d random-1.0.1.1 --------------------------------------
whereas
make configure
reports
runghc Setup.hs configure --ghc
by default only looks into the global package database. If you don't want to use the cabal tool to install your DoCon and stick with the `runghc Setup.hs ...` way, you have the choice to either - pass the --user flag to `runghc Setup.hs configure` so that it uses also the user package database where your random package sits (then DoCon is also installed for the user and not globally), or - install random in the global package database, `cabal install --global random` so that `runghc Setup.hs ...` finds the package in the global DB.
