Re: [Haskell-beginners] stack issues

Thanks Michael Having this in stack.yaml extra-deps: - gtk-0.14.2 # Override default flag values for local packages and extra-deps flags: { gtk: { have-quartz-gtk: true } } and adding gtk to cabal file helped me to resolve this issue! I still have different problem. I will try to find the solution or ask later when I'm out of ideas.

You need to specify the flag in the stack.yaml file, via something like:

flags: gtk: have-quartz-gtk: true

Is there a way to specify these flags in cabal file? I'm sure this will resolve my issue

This works for me

$ stack build gtk --flag gtk:have-quartz-gtk

but I sitll need to specify gtk also in cabal file (having it only in stack.yaml do not find the package)

but then I get

$ stack build

gtk-0.13.9: unregistering (flags changed from ["-fhave-quartz-gtk"] to [])

I found this

cabal install gtk -fhave-quartz-gtk --reinstall

but it does not help me when I run stack build afterwards..

Found that gtk was not installed. So I did brew install gtk

but I got different problem

Hi,

I'm new to cabal/stack. I want to use "stack build" to build my project.

I can not use latest gkt >= 0.14.2 because of setup: The pkg-config package 'cairo' version >=1.2.0 is required but it could

Neither can I now use older version gtk >=0.12.0 && < 0.13

While constructing the BuildPlan the following exceptions were encountered:

-- Failure when adding dependencies:

gtk: needed (>=0.12.0 && <0.13), 0.14.2 found (latest version available)

needed for package: ships-0.1.0.0

What can i do? Thanks
