Having dependency issues while trying to install ThreadScope with Stack. The issue seems to revolve around cairo-0.13.8.1

Question

I am trying to install ThreadScope using stack install threadscope.

Stack has given me recommendations of packages to add to my global stack.yaml file. I have followed all of its advice. This is from ~/.stack/global-project/stack.yaml:

extra-deps:
- gtk2hs-buildtools-0.13.8.0
- cairo-0.13.8.1
- glib-0.13.8.1
- gtk-0.15.5
- pango-0.13.8.1
- gio-0.13.8.1

Then I run:

stack install threadscope

Ok so cairo seems to be the problem.

What stands out to me in this error is the line: setup: The pkg-config package 'cairo' version ==1.2.0 || >1.2.0 is required. Hmm does this mean I should first attempt to install an older version of Cairo? I tried that but did not have any luck.

I have tried to run the commands:

stack upgrade --git --source-only
stack build cairo

I got the same error as when I ran stack install cairo.

If I run which stack I get back /home/nick/.local/bin/stack

Finally, here is what happens if I try stack install gtk2hs-buildtools:

Answer 1

pkg-config is looking for a package named cairo, which can be confusing as it has the same name as the Haskell cairo package. This is the useful part of the build log:

cairo> setup: The pkg-config package 'cairo' version ==1.2.0 || >1.2.0 is required
cairo> but it could not be found.

pkg-config is searching the PKG_CONFIG_PATH for a file named cairo.pc. On Debian this is provided by the libcairo2-dev package.
