I have just built allegro and its dependencies targeting iOS 7 and 8. I built real device and simulator binaries. I just created a simple test program to test things out. It is basically ex_physfs 1/*
2 * Example program for Allegro library.
3 *
4 * Demonstrate PhysicsFS addon.

When using the iOS 7 simulators, everything is working great. When I use any of the iOS 8 simulators, almost everything works, except when I rotate the screen left, I immediately get an ex_bad_access from EAGLView.m on line 192. - (BOOL)createFramebuffer { ALLEGRO_DISPLAY_IPHONE *d = (ALLEGRO_DISPLAY_IPHONE *)allegro_display; if (d->extra->adapter == 0 && [self respondsToSelector:@selector(contentScaleFactor)]) { scale = self.contentScaleFactor = [[UIScreen mainScreen] scale]; ALLEGRO_INFO("Screen scale is %f\n", self.contentScaleFactor); } else { scale = 1.0f; } The cause of the crash is that the allegro display pointer is NULL. I do not know why. I would be tempted to do: - (BOOL)createFramebuffer { ALLEGRO_DISPLAY_IPHONE *d = (ALLEGRO_DISPLAY_IPHONE *)allegro_display; if(d == NULL) return; if (d->extra->adapter == 0 && [self respondsToSelector:@selector(contentScaleFactor)]) { scale = self.contentScaleFactor = [[UIScreen mainScreen] scale]; ALLEGRO_INFO("Screen scale is %f\n", self.contentScaleFactor); } But that seems evil. In any case I wanted to bring this to the attention of the devs. I'm using Xcode 6.1 and OSX 10.9.4. I will soon be posting my binaries so that everyone with Xcode 6 can quickly try this for themselves. My binaries have a debug version with debug symbols.

Do you have a backtrace? "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

If you mean a stack trace then I can get that to you, if not, please describe what you mean. Agui GUI API -> https://github.com/jmasterx/Agui |

Two terms for the same thing "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

I can't seem to find a way to print a stack trace, but I'll just print it myself: #0 0x000a4280 in -[EAGLView createFramebuffer] at /Users/josh/Downloads/allegro5-5.1/src/iphone/EAGLView.m:192 EAGLView.m -> line 192 self EAGLView * 0x7b681130 0x7b681130 _cmd SEL "createFramebuffer" 0x001e5c38 d ALLEGRO_DISPLAY_IPHONE * NULL 0x00000000 depth_stencil_format GLint Contents of self at this point: self EAGLView * 0x7b681130 0x7b681130 UIView UIView context EAGLContext * nil 0x00000000 allegro_display ALLEGRO_DISPLAY * NULL 0x00000000 viewRenderbuffer GLuint 0 0 viewFramebuffer GLuint 0 0 depthRenderbuffer GLuint 0 0 touch_list _AL_LIST * 0x7b681990 0x7b681990 touch_id_set NSMutableIndexSet * 0 indexes 0x7b6819f0 primary_touch UITouch * nil 0x00000000 next_free_touch_id int 1 1 scale float 0 0 backingWidth GLint 0 0 backingHeight GLint 0 0 #1 0x000a40c9 in -[EAGLView layoutSubviews] at /Users/josh/Downloads/allegro5-5.1/src/iphone/EAGLView.m:161 EAGLView.m -> line 161 self EAGLView * 0x7b681130 0x7b681130 _cmd SEL "layoutSubviews" 0x01d1c520 Contents of self at this point: self EAGLView * 0x7b681130 0x7b681130 UIView UIView context EAGLContext * nil 0x00000000 allegro_display ALLEGRO_DISPLAY * NULL 0x00000000 viewRenderbuffer GLuint 0 0 viewFramebuffer GLuint 0 0 depthRenderbuffer GLuint 0 0 touch_list _AL_LIST * 0x7b681990 0x7b681990 touch_id_set NSMutableIndexSet * 0 indexes 0x7b6819f0 primary_touch UITouch * nil 0x00000000 next_free_touch_id int 1 1 scale float 0 0 backingWidth GLint 0 0 backingHeight GLint 0 0

jmasterx said: I can't seem to find a way to print a stack trace, but I'll just print it myself: I think you can set up a trigger in XCode's debugger that fires on any exception/crash. then it should give you a backtrace on crash. Though i think it'd let you get a backtrace even if you don't if you find the debugger window. -- |
