Hello,
I would like to compare two boost::function objects, but get an
"boost::operator ==' : 4 overloads have similar conversions" error.
On Visual Studio 2008 SP1, both Win32 and x64 target platform, the
following code does not compile:
boost::function one, two;
if (one==two)
one.clear();
I get the compile error messages below.
Any ideas, any help?
Regards and thank you in advance
