RenderTexture, compile fail on linux gcc

[93interactive]

Hi there, i am trying to user RenderTexture, but as soon as i include it as simple as this in my class:

Code: [Select]

class MyClass {
   private:
      sf::RenderTexture tex;
};

I get a compile error:

(SFML 2 current git clone, linuxmint and debian, gcc 4.6.3)

Code: [Select]

sf::RenderTexture cannot be copied, so classes that use it as a member cannot be used within containers such as std::vector directly. A vector of pointers to said class will work, though.
