This requires that we be able to update some targets before we've finished reading all Jamfiles, and is not supported at the moment.
Is it a bad idea to think about using a recursive bjam invocation for this sort of thing? That is, configure.run-test could invoke bjam to update the target associated with have_dlopen.
This is possible, but I'm concerned about performance implications of this. It's quite feasible to have 100, or 200 tests, running separate bjam for each one might be too slow.
You could run one bjam for all the tests
It's tricky. Say you have: if [ configure.has-lib foo ] { } if [ configure.has-lib bar ] { } Them if you invoke bjam once for configuration, from 'configure.has-lib', how that configure step knows that it should check not only for 'foo' but also for 'bar', when 'has-lib' for bar is not yet called. So, you'd have to have a separate file describing configure checks, not the above syntax. This is passable, but not ideal. - Volodya
