Re: [Boost-users] std::find_if, boost::mem_fn and boost::not1

not1 doesn't work well with boost::mem_fn applied to shared_ptr, but you may try

!boost::bind( &CEgg::IsHatched, _1 )

instead.

I tried the following:

bool SomeEggsHaveHatched() { tEggsVector basketOfEggs;

using boost::lambda::_1;

tEggsVector::const_iterator it = std::find_if( basketOfEggs.begin(), basketOfEggs.end(), boost::bind( &CEgg::IsHatched, _1 ) );

bool bSomeEggsHaveHatched = ( it != basketOfEggs.end() ); return bSomeEggsHaveHatched; }

but it won't compile, giving:

[...]

Any clues as to what's going on here?

You are using boost::bind with boost::lambda::_1. Remove the using boost::lambda::_1 line.
