I can't seem to get BOOST_CHECK_EQUAL with std::type_info
instances to compile with g++,
version (GCC) 4.1.2 20070925 (Red Hat 4.1.2-33)
Here's a simple test case:
------------------
#include <iostream>
#include <typeinfo>
#define BOOST_TEST_MAIN
#include
std::ostream &
operator<<(std::ostream &out, const std::type_info &info) {
return out << info.name();
}
BOOST_AUTO_TEST_CASE(Foo) {
std::cout << "Typeid of int is " << typeid(int) << "\n";
BOOST_CHECK_EQUAL(typeid(int), typeid(float));
}
------------------
g++ complains that there isn't an operator<< for type_info
in the BOOST_CHECK_EQUAL, even though it is used just fine
on the previous line.
Output:

Anyone know why this is?
