Re: [Boost-users] BOOST_ASSERT and others
Sorry, I should have checked!
It should be:
assert( 2 + 2 == 4 && "Adding numbers failed!" )

I use the trick
assert( 2 + 2 == 4 || "Adding numbers failed!" )
This will probably work for BOOST_ASSERT as well.
Are you sure about that || ? Looks to me like it would never fire. -- Dave Abrahams Boost Consulting www.boost-consulting.com _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users __________________________________________________ Do You Yahoo!?

That still won't fire. The concept is flawed. You cannot use assert()s to print debug messages, because when an assert() prints a message, it also stops the program. Sebastian Redl

Actually, it will. The versions of assert that I have seen will print the complete expression that failed before they stop the program. This will include the string.

My mistake. I thought the post was in answer to the second issue the author presented, that of printing debug messages. Sebastian Redl

For the second problem, i.e. printing a debug only message , may be a
simple solution is a macro like,
#ifdef _DEBUG
#define DEBUG_PRINT(msg) \
std::cerr << "DEBUG: " << msg << std::endl \
<<"("<<__FUNCTION__<<") "<
As does
assert( statement || !"Statement failed" )
which is 'faster' when statement == true
