Title: RenderWindow default constructor
Post by: Corbett on February 12, 2018, 11:04:15 pm

Hello. Simple question from noob. Tried to compile example project, everything looks OK:

int main()
{
  sf::RenderWindow MainRenderWindow((sf::VideoMode(800, 600), "my game");
  <skipped>
}

Changed a little:

sf::RenderWindow MainRenderWindow;
int main()
{
   MainRenderWindow.create(sf::VideoMode(800, 600), "my game");
}

It's crashed before entering main() function. I think it's crashed here:

void GlContext::initResource()
{
    Lock lock(mutex); <----- NULL value

So... If the default constructor crashes, may be better to delete it?
My config: VS 2017, SFML 2.4.2, build x64 Debug

Don't use globally initialize SFML resources.

Thanks, this works.

int main() {
  sf::RenderWindow MainRenderWindow;
  MainRenderWindow.create(sf::VideoMode(800, 600), "my game");
}
