Mach-o (Mach object) file format?This format is very rare in Chinese, and the most detailed is Apple's official documentation, this article does not repeat the contents of the Mach-o file format, only the experience when using IDA reverse iOS application.Mach-o Detailed documentation Reference: https://developer.apple.com/library/mac/documentation/DeveloperTools/Conceptual/MachORuntime/index.htmlThe Mach-o format can contain executable code for multiple target platforms, such as executable code

we'll go straight to finish.4, plug in the phone (the simulator is too slow, it is recommended to use the real machine) to run the project. We can see the following information in the C + + interface viewBuild of configuration Default for project Hellojni ****/users/lixiaoqiang/documents/install_tools/ndk/ Android-ndk-r10c/ndk-build all Android NDK:WARNING:APP_PLATFORM android-19 are larger than android:minsdkversion 3 in./A Ndroidmanifest.xml [arm64

Some of the most common causes are:1 build without the frameworkFor example, there's a piece of code I used OpenGL to introduce a header file#import Build, compile stage no problem, but link error undefined symbols for architecture xxx (here XXX may be armv7s,armv7 or arm64, depending on the configuration, will say later). The workaround is to add the opengles.framework to the build phases link Binary with libraries, and then compile on the OK2 Engine

is the address of class under 32 bits, but using bits mask under 64 bits to remove the real address, if you really need to, use runtime object_getClass and object_setClass methods. For a 64-bit explanation of ISA, you can read this articleResolve third-party Lib dependencies and Lipo commandsIn the form of the source code in the project of the third-party LIB, as long as the target plus arm64 compile the good.The disgusting thing is that the static l

Swift basics-ijkplayer Compilation This article has nothing to do with Swift, but it will be used later. This compilation uses Mac to compile the IOS version. below is the compilation process, and finally the entire project, because the download is too slow. 1. Download source code Git clone https://github.com/bbcallen/ijkplayer.git 2. Compile Cd ijkplayer-ios-stable ./Init-ios.sh // download dependency package here ./Compile-ffmpeg.sh // compile here, there are several options, I chose all 3.

If x86_64 is compiled, You need to assign the value of APP_ABI in Application. mk to: APP_ABI: = x86_64. 9. If you compile the armv8-a, You need to assign the APP_ABI value in Application. mk to: APP_ABI: = arm64-v8a 10.

currently 7 kinds. ARMV5,ARMV7 (since 2010), x86 (from 2011 onwards), MIPS (from 2012 onwards), Armv8,mips64 and x86_64 (from 2014), each of which is associated with a corresponding ABI. On an Android system, each CPU architecture corresponds to a abi:armeabi,armeabi-v7a,x86,mips,arm64-v8a,mips64,x86_64. The names of these packages cannot be changed casually.While we are in the development, As much as possible, each ABI-optimized. So file should not
