Nope, I confess to not understand manifests at all (does anyone?).

In any case that configuration is basically how we run our regression
tests - so it certainly should work - and your test case works OK for me

The only thing I can suggest is that since the regex lib is "just a bunch of
source files" that you either:

rebuild the libraries yourself: follow the getting started guide at but
basically you want to invoke:

bjam --with-regex --build-type=complete stage

which will put all the regex binaries in stage/lib.

Or... add the source files in libs/regex/src/*.cpp directly to your project,
and then add the #define BOOST_REGEX_NO_LIB to your project settings and

HTH, John.
