Crash

SDL Development

Hi, I’ve compiled the excellent Agar GUI Library,
(http://libagar.org)

However I couldn’t launch the demos because of
a crash (which doesn’t occur with my own SDL programs):

What’s going on ?

Apparently the OS is throwing a NSException on your call to
AG_InitGraphics. You should try to catch it and read the exception
message. That may give you a hint of what’s going on.On Fri, Aug 27, 2010 at 9:05 AM, julien CLEMENT wrote:
