here's one problem


E:\Documents and Settings\CodeBlocks Projects\test\main.cpp|28|warning: suggest parentheses around assignment used as truth value [-Wparentheses]|

if(event.type = sf::Event::Closed)

should be

if(event.type == sf::Event::Closed)

as for the font, make sure you have the correct version of sfml with the correct compiler
