iOS apps are now basically compiled with LLVM, and Xcode provides various settings to help you set the parameters for your compilation. One of these is to set the architecture of the compilation, which includes the following parameters: Architectures, Valid architectures, and build Active Architecture only.Some novice to these parameters often do not know how to choose, here is a brief introduction.Architectures: This refers to the set of instructions you want to support, such as: armv7,armv7s,

compileBuild Active Architecture only: whether to compile only the instruction set that is applicable to the current device (if this parameter is set to Yes, then if you debug with iphone 6, a binary that supports the arm64 instruction set is eventually generated; if you compile with iPhone4 , and eventually generates a binary that supports the ARMV7 instruction set, so it is generally set to Yes,release in debug mode.Here, we compile the final suppo

directly execute the user-state code. As a result, our usual approach to power-up is not feasible. What's more, the latest ROM in most of the arm64 system models (such as Samsung S6, Huawei P8), and some arm32-bit models (such as Samsung Note3, Samsung S5 and other mainstream models) has been PXN by default.Preliminary study on PXNIn a cve-2015-3636 exploit, we can finally control the value of the Sk->sk_prot->close pointer in the Inet_release functi

: Added 3 new ABIs, all 64-bit:arm64-v8a, x86_64, Mips64. Note: GCC 4.9 is the default compiler for 64-bit ABIs. Clang is currently version 3.4. Ndk_toolchain_version=clang may isn't work for arm64-v8a and MIPS64. Android-l is the first level with 64-bit support. Note that this apilevel is a temporary one, and only for L-preview. An actual API level number would replace it atl-release. This

Unity4.6.2 is nowOfficially released and available for download, this is the first official version of unity to support 64-bit iOS, with the latest il2cpp technology. download please visit:Http://unity3d.com/cn/unity/downloadIl2cpp is an innovative scripting technology developed within unity. It greatly improves the performance of all scripts in the project and is perfectly compatible with the Mono-aot solution used by the current iOS build. we can use Il2cpp to quickly port scripts to new platf

And then we guacai ...Here is a note of my record of being rejected in "express Freight":1, the first time the software is too complex, they will not use, need to provide detailed operational documentation, or video links.

Inability to spit out the groove, so this blames himself).2, January 2015 start to support

these two platforms is different, the simulator is I386 x86_64 architecture, and our device is ARMV7 arm64 architecture. When making a static link library, we also make two static link libraries for the real machine and simulator for different architectures, and when we want to use the static link library in our own project, if we run the static library version for the simulator on the emulator, It is very troublesome to switch to a static link libra

In the C-system language, you can use #if or #ifdef something like a compilation conditional branch to control which code needs to be compiled, and which code does not. There is no concept of macro definition in Swift, so we cannot use #ifdef a method to check whether a symbol is defined by a macro. But in order to control the compilation process and content, Swift also provides us with several simple mechanisms to tailor the content to the requirements.The first is #if this set of compiler tags

library file, then directly solve the corresponding SDK, the same half can be deleted. The operation flow is as follows:The general SDK will involve different architectures for compiling on different platforms, for example, if you want to compile on the emulator requires a compatible i386 architecture, the real machine needs to be compatible with the ARMV7 architecture. I'm going to separate the files from the different schemas first. On the console console command, view the supported schemas f

APP Slimming IntroductionThere are a large number of IOS devices on the market today, so there are a number of screen sizes and resolutions that require a lot of resources (such as PNG, JPEG, and binary PDF) to make an App appear on multiple screens. Unfortunately, this has resulted in users needing to download a huge package (the previous IOS version forces users to download all the App files, including IPad adaptation images they will never use on IPhone). 16G IPhone still has a lot of people
