Re: [Boost-users] bind, and member function with a parameter

13 Sep 2006

      Thanks Peter,

But how exactly do I specify _1? I have the same error if I do not 
specify any name space (as it is shown in the example)

boost::_1 is not defined
boost::bind::_1 generates "fatal error C1001: INTERNAL COMPILER ERROR"

I do not know which error I like the best :)

This is the code:

#include <vector>
#include <algorithm>
#include 

int main(int argc, char **argv)
{
	typedef std::vector T2Dimensional;
	T2Dimensional vec;
	std::for_each(vec.begin(),vec.end()
		,boost::bind(&std::vector<bool>::resize,_1,10));
	return 0;
}

Thanks.

I want to call a member function with a parameter from within an
algorithm.
http://boost.org/libs/bind/bind.html#with_algorithms gives an example:
void animation::advance(int ms);
std::vector<animation> anims;
std::for_each(anims.begin(), anims.end(),
      boost::bind(&animation::advance, _1, ms));
I am using boost::lambda:: before _1. I get an error error C2825:
'F::result_type': cannot form a qualified name
I am using MS VC7.1 and boost_1_33_1
Any ideas why this does not work? Thanks.
In 1.33, you can't use boost::bind with Lambda's placeholders. Either use 
Bind's ::_1 placeholder, or use boost::lambda::bind.
In 1.35, the code will work even with Lambda's placeholder.
