The following code compiles fine with MSVC10 and gcc:
#include <boost/tokenizer.hpp>
template <typename char_type_t>
struct S
{
typedef boost::char_separator<char_type_t> sep_type_t;
typedef boost::tokenizer<sep_type_t> tokenizer_t;
S(const std::string& messageString, const std::string& separator)
: sep_(separator.c_str()),
t_(messageString, sep_),
i_(t_.begin()) {}
sep_type_t sep_;
tokenizer_t t_;
typename tokenizer_t::iterator i_;
};
int main()
{
S<char> s("foo bar", " ");
}
If you are doing something different, please post the exact code.
