Hello, I'm trying to understand cabal-dev, and I seem to be missing some basic point, because I can't get dependencies between projects working properly.
I have two projects, let's call them P1 and P2. P2 depends on P1, as indicated by its cabal file build-depends field.
I run cabal-dev add-source ..\P1 inside P2
then cabal-dev install
Everything works fine, and my project compiles, with modules in P2 calling functions from P1.
Then I add a new function if an exposed module of P1. I rerun the cabal-dev add-source and cabal-dev install commands to tell P2 of the change, as per the cabal-dev documentation. I change a file in P2 to use the new function, the compilation fails.
If I check into the cabal-dev folder, I see the .hi file for my changed module has not been updated (old date).
What am I missing?

Thanks
