Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/fltk) and found some lint.

Here's what I've got...

For recipes/fltk:

• The "test" section was expected to be a dictionary, but got a NoneType.
• The recipe must have some tests.
• The "test" section was expected to be a dictionary, but got a NoneType.

additional deps

regarding the log from the windows build:

cannot find system zlib library - using built-in
-- 
cannot find system jpeg library - using built-in
-- 
cannot find system png library - using built-in

these libraries could be added as host and run-dependencies:

  host:
    - zlib
    - jpeg
    - libpng
  run:
    - zlib
    - jpeg
    - libpng

regarding the problem on windows, it seems like this recipe should be disabled for vc < 14 but somehow the test environment tries to use vc9... Maybe adding python as a host dependency solves this issue. At least I used this in the occt-feedstock. I don't know if this is good practice. Maybe someone from @conda-forge/core can have a look at the windows build.

regarding the missing tests: Maybe you can check for the existence of any fltk libraries...

btw. thanks for the work. This is really appreciated!

• Selectors are suggested to take a <two spaces>#<one space>[<expression>] form. See lines [28]

instead of doing this to force vc>=14, please do something like that in your build section:

build:
  number: 0
  skip: True  # [win and vc<14]

this will skip the build for windows and VC less than 14

As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
empty. please request that the channel administrator create

$ mkdir noarch

$ bzip2 -k noarch/repodata.json
You will need to adjust your conda configuration to proceed.

Just trigger the ci again and it should work now

[guyer]

@conda-forge-admin, please rerender

[looooo]

@conda-forge/core please create feedstock.

[CJ-Wright]

@looooo you might consider pinging @conda-forge/staged-recipes that group is a bit bigger, and all members have merge rights to staged-recipes.

[marcelotrevisani]

LGTM

I'm going to merge this! Sorry for the delay!

Thanks to put this in conda-forge! :)
