Hello,
I really like the BLL and would like to use it as much as possible. I
have run into a small problem though. My code looks like this:
#include
#include
#include <map>
#include <vector>
class A
{
public:
A(int a, int b) : a_(a), b_(b) { }
int a_;
int b_;
};
int main()
{
using namespace boost::lambda;
std::vector<A> v;
v.push_back(A(1, 2));
typedef std::map Map;
Map m;
for_each(v.begin(), v.end(),
bind(&Map::insert,
std::make_pair(bind(&A::a_, _1), bind(&A::b_, _1))));
return 0;
}
What I want to do is to populate a map with the information from the
vetctor v. For each element in v I want to insert a value and a key into
the map something like this:
void operator()(const A& a) const {
m_.insert(std::make_pair(a.a_, a.b_));
}
I found some information on how to use member variables as targets in
the BLL documentation and that is what I have tried to use in the code
above. It won't compile however, using g++ I get the following error:
g++ -c -o test.o test.cpp
test.cpp: In function `int main()':
test.cpp:27: error: no matching function for call to `bind(<unknown type>,

scons: *** [test.o] Error 1

If someone here has any ideas of how to accomplish this it would be
really nice!
Thanks in advance!
