I am having a problem and it seems after searching on the net it's
happening to others as well. However, I can not seem to see any replies on
how to fix it.
I am using Microsoft Visual C++ 2010, Boost 1.43, Lua 5.1.4, LuaBind 0.9
I have a class defined like so in C++:
class TestOutPolicy
{
public:
TestOutPolicy(void){};
~TestOutPolicy(void){};
void GetValue(const std::string& key, std::string& returnValue){
returnValue = "Got It";}
};
I bind the class like so:
luabind::module(lb)[
luabind::class_<TestOutPolicy>("TestOutPolicy")
.def(luabind::constructor<>())
.def("GetValue", &TestOutPolicy::GetValue, luabind::out_value(_3))
];
The errors when you attempt to compile using either the luabind::out_value
or luabind::pure_out_value are as follows:
