Skip platforms on conda-build

[Robert McGibbon]

Hi,

It would be useful to add an optional field to the conda-build meta.yaml schema to declare that a certain package is should not be built with a

particular platform (e.g. py34, or win-32, etc). Currently, this can be effectuated by putting this logic inside the build.sh/bld.bat files -- for example

by writing 'exit 1' in the bld.bat files to prevent the package from being built on windows -- but this has some disadvantages. In particular, if the

package has many dependencies that need to be downloaded from the web or unpacked, all of this downloading happens before the bld.bat

file is run, so there's a big waste of time.

Adding an optional field to the meta.yaml schema that permitted certain platforms or versions of python to be "blacklisted" would avoid this

headache.

```

# meta.yaml

build:

  skip: win-32, win-64

```

Thoughts?

Hi,

I think the proper way for you to do this is to open a pull request, or at least an issue, in the conda-build repo on Github. This way it'll be easier to discuss if it's feasible or not.


Cheers,
Carlos

Hi,

Sounds good. I implemented the feature in a PR

https://github.com/conda/conda-build/pull/399

I've done this by using selectors to delete some required field (like
the package name), but it doesn't provide a very helpful error
message.
