Re: Problems with 6.x compilers

...

6.4 and 6.4.1: When repeating a build (with ghc --make) all modules are rebuild even if nothing has changed. With earlier compilers, only linking takes place in this setting. Can I change this behaviour? I cannot develop this way.

Should not happen, if it does there is a bug. Can you tell us how to repeat the behaviour you're seeing? We aren't seeing any unecessary recompilation here.

I think I had that effect exactly when using -ddump-minimal-imports Wolfram
