how to automate or facilitate multiplatform build/test before committing?

Question

Our software is built on linux and windows platforms. Depending on the preference of the developer a contribution is developed and tested on either platform and then committed to our subversion repository. It then turns out that the contribution doesn't build on the other platform, and a fix has to be made. The fix on the other platform may again break the build on the original platform, and so on.

I'd rather see that a contribution is built (and regression tested) on the other platform as well before being committed. We have a continuous build server (CruiseControl), but that server builds from the repository. I am looking for a solution where the continuous build server builds on the other platform as a pre-commit check and then commits the stuff if the build and test succeed.

Any suggestions?

Answer 1

Teamcity handles pre-tested commit, you may be able to do something with the new build chaining features in 4.0( http://www.jetbrains.com/teamcity/features/newfeatures.html ). Agents are cross platform and can be configured to only run particular bits of the build, so could possibly be configured to only run a subset of tests.

Note that I haven't actually done this :)

It might be easier to have two branches, one where people checkin, and another which they merge their changes into after they have passed continuous integration.
