I've just added preliminary QT support to CVS. I'm now able to
cd to examples-v2/qt, run "bjam" there, and obtain an working
Felix, can you check it out, first with gcc, and then with Kylix?
However, this support has one *horrible* kluge. It directly adds "-lqt" to
the linker command line. It is probably OK here, but in general it bring the
following two questions:
1. The right way with qt would be:
1. I say "using qt ; "
2. The module "qt" declares a library target, and adds
"<library>the-target" to properties of all main targets
that use QT.
Clean, but only Jamfile modules, which are created in a special
way, are allowed to declare targets.
2. I want to use my own parser generator, and to have it as part of
build process. What I mean is: the generator is used for building
my project, but if the sources for the generator change, it should
be rebuild, together with all files in my project which it produces.
No problem, it's possible to use other projects in Jamfile. However,
other project wants to declare new target types and new generators and
new features. It's not possible to allow that everywhere. (Other project
can be referred from any Jamfile).
Did I explained the problems well enough? Looks like the first one is
rather technical. We'd need to allow "qt.jam" to create fake project
(i.e. not related to any Jamfile), and declare targets there.
The second looks like a design question. Would it be acceptable if we
say that project which declare features/types/generators can be referred
only from project-root files. This way, we'd collect full set of features,
etc. before generating the first target.
