Did you run it multiple times and get that output? Also you usually want stack build.

My work projects use Stack and it'll *only* build my current project when I run stack build (and be fairly fast) unless I changed the source, a cabal file, or a stack.yaml.

If you did run it multiple times and got that output, is something touching those directories between builds?

i tried, but the time is still around 1m20s.

The syntax is:

packages:
- '.'
- location: ../Nomyx-Core
  extra-dep: true
- location: ../Nomyx-Language
  extra-dep: true
- location: ../Nomyx-Web
  extra-dep: true

Right?

It spends a lot of time apparently recompiling dependencies:

You need to specify extra-deps: true for Nomyx-* if you to cache the build results and treat them like dependencies rather than core parts of your project.

Do you have additional packages other than '.' specified in your stack.yaml? If so, are they specified with extra-dep: true or extra-dep: false or not specified at all?

Hi guys,

I have an application with around 7K loc in 4 packages. It takes 1min30 to compile with stack.

Is it a normal compilation time?

My computer is fairly recent with Intel i7... I run some music in background :).

Is there some statistics about compilation time somewhere?

Thanks.
