[Buildroot] Reduce time for a make, possible?

[Tony Mozi]

Hi,
When we make a change in the buildroot like add or remove an option, it's necessary to do 'make clean' then a 'make'.
Is it possible to reduce the time of this operation which is very long?

For the moment, it is not possible safely. However, during the last
Buildroot Working Day last week, this was one of the main topic that we
discussed. So it's definitely not a feature that will be available in
the coming weeks, but pretty likely in the coming months or so.

Cheers,

Thomas

Yes. For most situations you can safely add new applications without
rebuilding everything (the problem is with libraries as other
libs/programs might want to enable support for that library). Removing
stuff is more difficult, so there you need to rebuild.

Once the external toolchain stuff is more robust and we have better
package removal/addition tracking things will get better.
