For A i type:

The binaries are created. However, A uses B and when i then change the library B:
{{{
echo ""improved code"" >> Main.hs

runhaskell Setup.hs build
runhaskell Setup.hs install
}}}
The library is installed fine, but recompiling A does not work, because Cabal only seems to stat

So one always has to `runhaskell Setup.hs clean` the workspace if not sure if something in the libs changed (in a script ...)",enhancement,closed,normal,Cabal-2.0,Cabal library,1.1.6,normal,fixed,,,hard (< 1 day),6.6,
