crash in the carbon event loop

Rate this Message:
Hi
I have a weird crash in the carbon RunApplicationEventLoop() function. According to the backtrace it crash somewhere in this method without touching one of my event handler. To be more precise mouse events work just fine but keyboard events seem to crash the application. Whatever I do with the handlers doesn't seem to change anything...(like disabling keyboard or mouse events handler or whatever..) I don't have a clue of what I am doing wrong so if someone had this kind of problems all advices are welcome..

Getting back into MacOSX development after some time off

Rate this Message:
Hello,
I am returning back to Mac OSX development after some time off. I am resurrecting an app I haven't touched since 2007. I was able to get it to build to 10.5 SDK. Any pointers in migrating to 10.6 SDK. I know this is a rather general question. Alse I am using MOKit. Has anybody migrated MOKit to 10.6? Thanks, Jerry Porter _______________________________________________ MacOSX-dev mailing list MacOSX-dev@... http://www.omnigroup.com/mailman/listinfo/macosx-dev |

I also know this is a rather general answer. You'll have to be more specific. The source for MOKit is available at <http://sourceforge.net/projects/mokit/files/>. You can modify that source to compile for 10.6 too. Kiel _______________________________________________ MacOSX-dev mailing list MacOSX-dev@... http://www.omnigroup.com/mailman/listinfo/macosx-dev |

I took a look at it just now and it is pretty outdated. There might be some things of value, but I would consider just removing it from your project and backfilling.

Thanks,
I think I figured out how to "migrate" to 10.6 SDK in my code. I started by playing with the Active SDK and the architecture settings. I will just work my way through the deprecation warnings. I have the source to MOKit and I will probably toss it once I have gotten up to speed on the new UI enhancements now available in 10.6. I also have to get my head wrapped around the new IB too.

Remember that the SDK should be set to the NEWEST version of Mac OS X that you want to run on and the DEPLOYMENT_TARGET to the oldest. For example, for PowerPC Leopard, Intel Snow Leopard and deploy to Tiger: SDKROOT = macosx10.6 SDKROOT[arch=ppc] = macosx10.5 MACOSX_DEPLOYMENT_TARGET = 10.4 You should probably be at least testing with an x86_64 architecture. I usually use: ARCHS = $(ARCHS_STANDARD_32_BIT) x86_64 Note that this is the same for both debug and release configurations. If you only want to build the native architecture when debugging use this: ONLY_ACTIVE_ARCH = YES Note: the above build setting will cut-n-paste into your project or target build settings (if the appropriate table view has focus). -- Enjoy, George Warner, Schizophrenic Optimization Scientist Apple Developer Technical Support (DTS) _______________________________________________ MacOSX-dev mailing list MacOSX-dev@... http://www.omnigroup.com/mailman/listinfo/macosx-dev |

Can it be a release of something else than an event that could cause this crash? Any time you have a memory management bug, it can manifest itself as something else. And since you didn't post your code or the backtrace, there's really nothing more informative anyone can say. Things to take away: 1) If you crash, it's usually because of an over-release. 2) You should be running the clang static analyzer frequently. Especially after you crash. 3) If fixing the static analyzer's warnings doesn't help, and you decide to post to a mailing list, you need to include the backtrace and any code involved. --Kyle Sluder _______________________________________________ MacOSX-dev mailing list MacOSX-dev@... http://www.omnigroup.com/mailman/listinfo/macosx-dev |

Thank,
However I am not to concerned with being backward compatible. I just want to move my code forward. BTW so far so good, purging out the warnings so far.

Interesting. What are those "warnings I need" you don't get? The only problems I had were with new/obsolete delegate methods, because compiler doesn't know which are going to be called and which are not going to be called. And no SDK setting can help you with that. izidor _______________________________________________ MacOSX-dev mailing list MacOSX-dev@... http://www.omnigroup.com/mailman/listinfo/macosx-dev |

> Interesting. What are those "warnings I need" you don't get? I'm not Matt, but the issue he's probably referring to is calling methods that are only available in the newer OS versions. The compiler/linker will not tell you that you're calling one of those, and that you need to add checks or fallbacks for the older OS versions you support. OTOH, by using the oldest system version you support as the SDK, you *can't* call any newer APIs by accident, as they're simply not defined. If you really want to use newer API, you have to jump through a few hoops, of course (put new-OS-specific code in a loadable bundle, declare the methods yourself and look them up manually, or whatever else is appropriate in your case). The difference is, you're making the compatibility-breaking calls explicit.
