Try original version.
#include <vector>
#include <algorithm>
#include <boost/utility.hpp>
int main()
{
std::vector<int*> col;
std::for_each( col.begin(), col.end(),
&boost::checked_delete<int> );
}
I do not rememeber what written in Standard about address of inline
function and instantiation in this case, but MSVC produce following
link error:
test_area.obj : error LNK2001: unresolved external symbol "void
__cdecl boost::checked_delete(int *)" (?
checked_delete_at_boost@@YAXPAH_at_Z)
Debug/test_area.exe : fatal error LNK1120: 1 unresolved externals
