Re: [Boost-users] problem compiling with threads and stlport

I saw yours and Davids posts, and thought it looked the same, but then I 
realised yours was std::allocator< ... etc, while mine is 
_STL::allocator<... . I find that when I use the normal std everything 
works, but not when I try to use STLPort, so I'm confident I'm linking 
to the libraries, but they don't 
contain_STL::allocator<boost::function_base>
I don't know if this is a problem in the way I built boost or STLPort, 
or with my makefile or environment.

thanks for noticing though!
