Xcode 6.1 Version When you create a new project, you will give us some default build Settings, one of which is important is the architecture setting, first look at a picture, as follows:In the second row of architectures, the standard schema is set, which includes the ARMV7, Arm64. This compilation option specifies which instruction sets the project will be compiled to support, which is implemented by compiling the corresponding binary packets, and if

Apple requires the old app to support 64-bit after June, and the new app must support 64bit from 2.1 onwards. Since we used Luajit, the luajit2.0.x version only supports 32bit. 64bit has been supported in version 2.1, but it is now alpha version only. the following Luajit libraries support ARM64,ARMV7 and emulators after compilation. That is, a library supports all CPUs compiled by 64bit, and does not require special treatment for the new and old ipho

When introducing a third-party Lib (. A) library, it is often caused by the introduction of the same open source code as your existing project in the third-party Lib library. O Conflict, recently in the integration of Han Wang Business card recognition occurred asihttp. o conflict. What I want to say is that the source code, like this one, is not supposed to be included in the Lib library, even if you want to include it, you have to change the name. But there is no way that now that people conta

Luajit2.1 64-bit compilation and general library for iOS, luajit2.1iosApple requires that the old app support 64-bit after March, and the new app must support 64-bit since 2.1. We use luajit, while luajit2.0.x only supports 32bit. 64-bit is supported in version 2.1, but only alpha is supported currently. The following luajit Library supports arm64, armv7, and Simulators after compilation. That is, a library supports 64-bit compilation of all CPUs and

ExampleOn Android phone execution getprop | grep cpu , you will get a message similar to the following:[ro.product.cpu.abi]: [arm64-v8a][ro.product.cpu.abilist]: [arm64-v8a,armeabi-v7a,armeabi][ro.product.cpu.abilist32]: [armeabi-v7a,armeabi][ro.product.cpu.abilist64]: [arm64-v8a]Each CPU supports a different set of instructions (instruction set), a combination o

The main function is to put all the object files into a package, generate an export symbol table, so that other programs can know the structure of this file.For the Apple system, the rich device contains a variety of architecture platforms, ARMV7, Arm64, i386, x86_64 is the most common instruction se

This is basically nothing to do with Swift, but it will be used later, this compilation is using the Mac to compile the iOS version, the following is the compilation process, and finally the whole project, because the download is too slow.1.

Apple officially will not allow the submission of arm64 applications on February 1, 2015, which is a Damocles sword for those of us who develop mobile applications. I wrote an article in front of how apps on iOS are compatible with 32-bit systems and 64-bit systems, but that's still an armchair stage, not in combat. By January 2015, I finally started the arm64 upgrade of the app after the app submitted a ne

actual application process. Therefore, the IJKPlayer open-source by bilibili is generally used in the industry, douyu TV and others are self-built based on IJKPlayer. Their technical solutions are mature, stable, and easy to use. The project compilation scripts are simple and flexible. Ii. Use of IJKPlayer. After the project is cloned, the first thing to do is to configure Codec, because IJKPlayer uses ffmpeg for Codec. If it is not cropped, the compiled library will be surprisingly large. Let'

The early Android system almost only supported the ARMV5 CPU architecture, do you know how many of these are supported today? 7 kinds.The Android system now supports the following seven different CPU architectures: 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.The Application Binary interface (application binary Interface) defines how binary files (especially. so files) are e

Features and background introductionAs early as 2014 in June, Mountain View City announced that the upcoming Android L will be supported by 64-bit processors.A few weeks later, version 10 of the revised NDK (Native development Kit, native Development Kit) was released, supporting three 64-bit architectures of chips,namely arm64-v8a, x86_64 and Mips64. I believe that developers know

With docker, you can easily try the aarch64 environment. Compilation can also be executed. Preparation Use Ubuntu 14.04 (x86_64. First install docker.

, profile.Personally, Xcode now does not have to duplicate release configuration to create a special package AppStore or adhoc or other configurations, because the feeling is not convenient how much, just omitted the choice certificate, But you still set the archive option.Generally speaking, adhoc, Appstore\inhouse, both use the same certificate, only the profile is different, simple selection of profile, is not more convenient.Instruction SetLet's talk about the instruction set for iOS devices
