First I get not BOOST_MPL_ASSERT compilable on VC 7.1. From the documentation I could read that it could replace BOOST_MPL_ASSERT_IS_SAME, but I removed it completely, and switched back to BOOST_STATIC_ASSERT.
Please post the code.
That's simple:
#include "boost/mpl/assert.hpp"
void Testmpl6() { BOOST_MPL_ASSERT(false); //fails with error C2143: syntax error : missing '}' before '(' BOOST_MPL_ASSERT((false)); //same error }
But neither of those is supposed to work. BOOST_MPL_ASSERT((<bool-valued-nullary-metafunction>)) is the only legal way to use this macro. For example, BOOST_MPL_ASSERT((boost::mpl::false_)) which of course will fail to compile because the condition is false. BOOST_MPL_ASSERT((boost::mpl::true_)) will pass. If you are replacing BOOST_MPL_ASSERT_IS_SAME(x, y) you need to write: BOOST_MPL_ASSERT((boost::is_same<x,y>)) Can you help me to understand what needs to be fixed in the documentation so that this is clear? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
