For the following code: // start of code #include <iostream> #include <string> #include int main() { using namespace std; using namespace boost; string s = "first second third"; tokenizer<> tok(s); for(tokenizer<>::iterator i = tok.begin(); i != tok.end(); ++i) cout << *i << "\n"; } // end of code With the Sun CC compiler (Sun WorkShop 6 update 2 C++ 5.3), I get the following error message: "/usr/include/boost/iterator/iterator_facade.hpp", line 623: Error: Could not find a match for boost::iterator_core_access::equal(const boost::token_iterator, const char*, std::basic_string>, const boost::token_iterator, const char*, std::basic_string>, boost::is_convertible, const char*, std::basic_string>, boost::token_iterator, const char*, std::basic_string>>). "t.cpp", line 15: Where: While instantiating "boost::operator!=, const char*, std::basic_string>, std::basic_string, boost::forward_traversal_tag, const std::basic_string&, int, boost::token_iterator, const char*, std::basic_string>, std::basic_string, boost::forward_traversal_tag, const std::basic_string&, int>(const boost::iterator_facade, const char*, std::basic_string>, std::basic_string, boost::forward_traversal_tag, const std::basic_string&, int>&, const boost::iterator_facade, const char*, std::basic_string>, std::basic_string, boost::forward_traversal_tag, const std::basic_string&, int>&)". "t.cpp", line 15: Where: Instantiated from non-template code. 1 Error(s) detected. What could be the problem here? If Sun CC 5.3 doesnt support boost::tokenizer at all, are there any workarounds that I could use?
