Re: [Haskell-cafe] cabal-dev add-source

That's exactly what I'm doing, and I was exactly following these notes, but it doesn't work. This google+ post and the answers to it ( https://plus.google.com/102016502921512042165/posts/TGaENqWfubP) lead me to at least one solution that seems to work: you need to unregister the changed package first. So cabal-dev ghc-pkg unregister --force P1 cabal-dev add-source ../P1 cabal-dev install Does the trick. There seems to be a way to pass a --reinstall flag to cabal-dev install but I haven't gotten it to work yet. Thanks JP On Fri, Feb 8, 2013 at 6:53 PM, Blake Rain wrote:

You need to call cabal-dev add-source on P1 again to copy over the sdist, then do a cabal-dev install.

See notes under "Using a sandbox-local Hackage" on https://github.com/creswick/cabal-dev

Hello, I'm trying to understand cabal-dev, and I seem to be missing some

...

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

basic point, because I can't get dependencies between projects working properly. 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
