Hmm, I thought the work James did with the platform would make this work better. Maybe not.
I'm trying to figure out the best approach. I just get the feeling Build All builds too much, and Build Project builds doesn't build enough. And both have the opportunity to build multiple configs per projects instead of the one you care about.
What's starting to come to mind is an idea I first saw in Visual Studio, the idea of an Active Project (or StartUp project as it seems to be called now) and and Active Build Config. We could then add a Build Active Project command that would build that
project independent of the selection. The other side of that is the Active Config, which would then set the active configs for all projects the Active project depends on based on the CDT's References. That way we should be able ensure we build only that config.
We kinda went part way there with the current build/manage config buttons.
The other thing bugging me is clean. I usually only want to clean a single project so I can kick it to rebuild. Yet the platform cleans that project and all the projects it depends on. In Java and other languages, maybe that's what you want to do. But
in C/C++ where projects are usually less coupled than that, you don't really want that. At least I don't think so.
Thoughts?

To my knowledge, the Platform's project references page does nothing for CDT projects and can only serve to confuse the user. I recently opened a bugzilla against the platform as there is no clean way for products (plural) to suppress the platform's properties page: https://bugs.eclipse.org/bugs/show_bug.cgi?id=385431 We avoid it in CodeWarrior with a hack. We're hoping the platform will eventually give us a proper way to do it. John From:

Playing with some real world projects, I was trying to set up build configs for a group of projects. Each project could have up to 8 build configs. There's a executable project and about 5 library projects and I'm trying to set up the dependencies between
the executable and the libraries for configs of the same names. Now when you switch configs, it's actually pretty difficult to ensure that the configs are set the same for all projects. Luckily the CDT builders follows the config dependencies and ensures that
the dependent projects are build properly. However, the Platform project references will also trigger a build of potentially the wrong config, or build a project a second time, which is a waste of time.
So the question I have, do we really need to set the platform project reference when we create a build config dependency in the Paths and Symbols -> References tab?
The downside is Build All which may build things out of order, but then again, the CDT builder will redo the project builds as needed. Or is there a better way to do this?
Have we had this conversation before?
Thanks,
Doug.
