C:\boost_1_32_0\boost/shared_ptr.hpp(431) : error C2039: 'basic_ostream' : is not a member of '_STL'
followed by a bunch of errors stemming from the absence of basic_ostream.
I looked through shared_ptr.hpp's inclusion path for missing references to ostream or somesuch but could find none.
(building with <stlport-iostream>on works, but does not achieve what I want)
Could it be that my path settings are leading to ostream never being included?
I don't see how, BTW I don't know which compiler you are using, but STLport doesn't really work with VC7.1 unless you use it's own iostreams (should work in this mode with VC6 though). If all else fails then just add the regex source directly to your project, and then see what happens, but basically this looks like an STLPort setup issue. Sorry I can't be more helpful, John.
