Add support for modular build structure. #854

Closed grafikrobot closed 4 months ago

grafikrobot commented 7 months ago

This adds the minimal set of declarations to make it possible to have both legacy non-modular building work with new modular building. It allows incremental addition in libraries to get them ready for modular building.

This is a temporary state though. After all libraries, tools, and testing build in this mixed mode another version of the jamroot will be needed to remove the legacy build handling.

@mclow , @glenfe , any objections to this?

grafikrobot commented 6 months ago

Preparing a different PR that allows for an easier to manage transition to replace this one.

Close & open for CI to reset.

I've looked at this, and I don't think I know enough about Jamfiles to make reasonable comments.

Okay, this is truly now ready. I've now made all the changes to support both not-modular, fully-modular, and everything in between. You can see the testing in these two repos:

https://github.com/grafikrobot/boostorg.boost/actions - Has this change and all the libs and tools modified with the regular boost-root.
https://github.com/grafikrobot/boost-b2-modular/actions/workflows/check-libs.yml - Has a root-less structure with all the libraries, and the boost_install tool as the above. But only with a project-config.jam as a fully-modular setup. Note the CI on this is not expected to pass. As it's trying to fully build everything blindly. And many libs have failing tests in the regular course.

The change of BOOST_VERSION from 1.85.0 to 1.86.0 is probably no longer necessary.

You could press the update/rebase button to resolve that. I don't get that button apparently.

@pdimov manually merged current develop to resolve that.
