Hi monks,

I was reading SDL::Manual, and after having followed instructions for installation (with cpan), I tried the first examples.

Creating a window works. I get a black window with this basic code:

use strict; use warnings; use SDL; use SDLx::App; my $app = SDLx::App->new(w => 400, h => 400); sleep(4);

But if I try to draw something, such as a line (as in the book):

use strict; use warnings; use SDL; use SDLx::App; my $app = SDLx::App->new(w => 400, h => 400, d => 32); $app->draw_line( [200, 20], [20, 200], [255, 255, 0, 255] ); $app->update(); sleep(4);

Then the screen stays totally black. No error message, no warning. I guess something is wrong with the installation of the library. Any idea on how I could fix that?

UPDATE: It seems that I can make things appear when I call $app->run();

It's not what is in the manual, though. And when I call this, I can't stop the processus anymore, not even with Ctrl-C :/
