ios osx app-store dyld
Is there a common way to detect if a symbol exists or not? Like CGPathCreateCopyByStrokingPath() in iOS5, which is only available on iOS5 and later. If I compile and run apps using this routine on iOS 4 devices, I would get a runtime dyld error.In Objective-C, +class and other utility APIs can be used to determine the existence of some class or some selector, is there any API to do this on dyld-ed symbols?Or is it under Apple’s permission to use dyld functions for an AppStore oriented app?

osx dyld
I have a bunch of dylibs which i need to load at runtime from application bundle. I have noticed that if i put my dylibs in /usr/lib folder, then application is able to load it. I have gone thru install_name_tool manual but haven’t got a clue on how can i make my application load these dylibs from .app/contents/Frameworks folder.Could please someone help me out with this??

xcode osx dyld search-path
I have a framework with installation directory @rpath and app with runpath search path @loader_path/../Frameworks which uses this framework.After building I have My.app and My.framework in Build/Products/Debug directory and I don’t copy My.framework into My.app bundle.If I run My.app from Xcode it runs and loads framework from Build/Products/Debug directory. If I run my app from Finder it can’t load the framework as expected.Does Xcode set runtime search path and how? DYLD_LIBRARY_PATH?

xcode frameworks dyld
I’m totally new to Xcode and Objective-C, but an experienced (web) programmer otherwise. I want to create an app that includes a self-made framework.Now I’ve read quite a bit on it, I think I’ve got a reasonable grasp of how OS X resolves dependencies at runtime, and the role of @rpath, @executable_path and @loader_path.I did the following to create the framework:Create new Cocoa Framework named Test. Set installation directory to “@rpath”. Add “Test.h” to public headers. Click run. Right click

osx gcc linker shared-libraries dyld
I want to set under Mac OSX the runtime path of an executable (for the linker) at compile time, such that shared libraries at non-standard locations are found by the dynamic linker at program start.Under Linux this is possible with -Xlinker -rpath -Xlinker /path/to (or using -Wl,-path,/path/to) and under Solaris you can add -R/path/to to the compiler command line.I found some information that Mac OS X gcc has -rpath support since 1.5 – which is perhaps ~ 2 years old, now.I tried to get it workin

Does anyone know what the format of the data pointed to by the Mach-O LC_FUNCTION_STARTS command is?The most information I could find is in the loader.h header file:#define LC_FUNCTION_STARTS 0x26 /* compressed table of function start addresses */I see the dyldinfo tool has a -function_starts option which analyzes this data and the tool is open source, but the latest released version of the tool doesn’t contain the support:http://opensource.apple.com/source/ld64/ld64-97.2/src/other/dyldinfo.cppD

I’m getting the following message in my users’ crash logs:Dyld Error Message: Symbol not found: _OBJC_CLASS_$_NSMetadataQuerySo I understand the solution is that I should be making the Foundation framework “Optional”. But what’s bizzare to me is this crash only happens on some iOS4 devices, but not others, and it doesn’t crash in the 4.3 simulator either. It’s only happening on iPads (running iOS4) specifically, but even then, it’s only on some of them. Can someone explain why that might be? I

I need to find the offset of a local symbol in a shared library on OS X. Local symbol as in non-exported symbol. Therefore dyld(“symbol_name”) will not work.I can however use nm to find these offsets, for example$ nm /System/Library/PrivateFrameworks/DesktopServicesPriv.framework/DesktopServicesPriv | grep -e ChildSetLabel -e NodeVolumeEject 000000000006cccd T _NodeVolumeEject 000000000009dbd7 t __ChildSetLabelThere we see the exported (T) symbol NodeVolumeEject which’s offset 0x6cccd I can eas

c osx dyld
I have a really odd situation with dynamic symbol binding on OS X that I’m hoping to get some clues on how to resolve.I have an application, written in C, which uses dlopen() to dynamically load modules at runtime. Some of these modules export global symbols, which may be used by other modules loaded later.We have one module (which I’ll call weird_module.so) which exports global symbols, one of which is weird_module_function. If weird_module.so gets linked with a particular library (which I’ll c

I’ve compiled a command-line tool against some C++ dynamic libraries using GCC 4.7 on Mac OS X 10.8. On the development system, the compiler was installed by MacPorts into /opt/local and the libraries reside in /usr/local/lib. The dynamic libraries are compiled from source alongside the program. (But they’re built by cmake and I don’t want to mess with that system.)When I try to run it on another machine by putting the necessary dylibs into the executable’s directory and DYLD_LIBRARY_PATH, it co

I’ve been watching a set of 200 tutorials by thenewboston and it is great!Only problem is, i can’t start the emulator. I think it has something to do with the fact when it asks me how much space the sdcard should hold – when i try to prEss enter – it won’t let me continue.. [2013-01-22 0
