Fat Mach-O Executable Multi-purpose?

由 别来无恙 提交于 2019-12-04 06:46:48
问题 I am currently working with Mach-O Executables on my Mac and A question just came across me, Can a single Fat Mach-O Executable file have multiple purposes? Eg. Could I Have a single Mach-O Executable File with a Fat Header specifying 2 Executables: Executable 1 : This executable could be a Dynamic Library allowing Its code to be loaded in external applications. and Executable 2 : This executable could be an Executable allowing It to be independently launched through Terminal or as an

Apple Mach-O Linker errors and I don't know what to do

由 天涯浪子 提交于 2019-12-03 19:11:07
问题 I cannot compile my project for the device or simulator anymore. I get 13 Apple Mach-O-Linker errors. It all started after I failed attempt to use sharekit. Here is the log from the error: ld: warning: directory not found for option '-F/Users/bbrandy95/Documents/Broken Brandsonic Web Projects/Brandsonic Web mobile/../../Downloads/0.2.1gm1/iphoneos4.0/System/Library/Frameworks' Undefined symbols for architecture armv7: "_OBJC_CLASS_$_NSURLRequest", referenced from: objc-class-ref in Brandsonic

问题 I know this Question has been asked many times before, but none has solved my problem uptill now. I know that this error occurs when you got multiple copies of your file in project. I tried to clean the build, delete any LoginController.m file in Compile Sources and then build. Fine - no errors. When I added my LoginController.m file in Complie resources, compiler again gave the same error. Next I what I tried is delete all .m files from Compile Sources, clean and rebuild successfully, and

mach_vm_region_recurse, mapping memory and shared libraries on osx

由 只愿长相守 提交于 2019-12-03 08:27:36
I'm using vm_region_recurse_64 to map out the memory for a given process, vmmap style. Trying to get a complete list of shared libraries loaded by the application by examining each library's Mach-O header in memory, however, vm_region_recurse seems to disagree with the vmmap command line tool about specifically where some of the specific memory sections begin and end. This becomes especially true in the 90000000-a0000000 system submap where most of the os shared libraries are loaded. And now I'm kind of stumped. I can list memory segments, tell generally what type they are, and read from them

Mach-O symbol stubs (IOS)

由 北慕城南 提交于 2019-12-03 06:22:33
问题 I am trying to understand how Mach-o files work, and have made a good deal of progress with the online resources available (In particular, the Apple page here: http://developer.apple.com/library/mac/#documentation/developertools/conceptual/MachORuntime/Reference/reference.html), but I have hit a roadblock on understanding how symbol stubs work. Using "otool -l" I see the following section: Section sectname __symbolstub1 segname __TEXT addr 0x00005fc0 size 0x00000040 offset 20416 align 2^2 (4)

How to insert a LC_LOAD_DYLIB command into a Mach-O binary or join a static library to an existing binary (IOS)

由 落爺英雄遲暮 提交于 2019-12-03 05:11:56
问题 This is the first time I am asking on stackoverflow and I am desperate. My task is to load a dylib or join a static lib to an already existing executable for an IOS device. I will be using the static void __attribute__((constructor)) initialize(void) to start the swizzling. This executable is for in house enterprise appstore so i do not need to go thru the apple appstore (since they will reject it). The reason for this is to take an existing IPA from a customer and their signing keys and add
