Clean up after building

[Olaf van der Spek <olafvdspek@…>]

After building boost with build-type=complete, 2+ gbyte of object files, pch files and program databases is left behind. It'd be nice if there's an option to clean up intermediate files.

[Steven Watanabe]

Just delete bin.v2. I don't think there's much point to adding another option when there's already an easy solution.

[Olaf van der Spek <olafvdspek@…>]

Thanks, perhaps that could be included in the getting started guide?

If b2 would delete intermediate files as soon as a target is build the build would consume less disk space. ;)

[Vladimir Prus]

To be honest, I'm unaware of *any* build system that removes intermediate files.

Different arguments can be made about adding this to getting started guide, though it probably won't be a big deal.

Replying to vladimir_prus:

Sure, but what's your point? Isn't it a good idea?

[Vladimir Prus]

The point is that if a good idea is not implemented anywhere else, maybe the user demand for it is not very high, and it might not be the most important thing to address (e.g. compared to some of the documentation issue you brought up recently).

As for the merits of the idea, I'm not sure. As Steven said, removing entire "bin" directory is easy, and doing this automatically by default will inconvenience people who might want to build repeatedly.

Demand for smartphones wasn't high before the iPhone was released either...

Obviously it shouldn't be the default and manually deleting the bin dir is fine (for now).
