Again with the annoying string conversion error.

[Arthur123]

IDE - Microsoft Visual C++ Express Edition (2008, I think.)
SDK/Library/whateverit'scalled - SFML

Putting/removing 'L' doesn't seem to do much good... & I couldn't find anything of use on the web; so I'd appreciate somebody telling me why the compiler is hating on me. :)

#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <iostream>
void main(){
	sf::Window App(sf::VideoMode(800,600,32), L"T_T"); //cannot convert from 'const wchar_t [4]' to 'const std::string'
	std::cout << ">SDKLFJS:LDKFJ" << std::endl;}

if you look at this

sf::Window::Window(sf::VideoMode,const std::string &,unsigned long,const sf::WindowSettings &)

you see that the constructor wants more parameter than you supplied. Additionally

unsigned long,const sf::WindowSettings &

The 'L' is wrong. Just give it what it wants and it will be satisfied.

#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <iostream>
void main(){
	sf::Window App(sf::VideoMode(800,600,32), L"T_T", sf::Style::Fullscreen); //cannot convert from 'const wchar_t [4]' to 'const std::string' 

By removing the L, it generates 4 errors instead of one. :/

But if I DO use the L...

Yes, but you're thru. Now the compiler is satisfied and the linker whinges. You must provide the appropriate library
