[Boost-users] Boost 1.70 unordered_set problem with Sun Solaris Studio 12.3

Hi again, this time I've a problem to compile a simple program using an unordered_set. The program is the following: --- //main.cpp #include <boost/config.hpp> #include <boost/unordered_set.hpp> #include <boost/functional/hash.hpp> int main() { boost::unordered::unordered_set<std::string> set; return 0; } --- I compile it with the command below: CC main.cpp -o test -library=stlport4 -I/.../boost_1_70_0/ and I got the error: ir_build_type(): unexpected type Please help me!! Thank you, Mirko
