facebook infer 代码静态检测

1. infer 相关网站

Infer 中文 | APP 的静态分析工具

2. 环境配置

infer 安装过程中会依赖一些工具（Homebrew，OPAM）

1、HomeBrew 安装：
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2、OPAM 安装：
sudo brew install opam  

3、clane 安装
xcode-select --install

3. infer 下载 与 安装配置

infer github地址

-=-=-=-=-=-=-=-=- github 上的 下载应该都会，不说了 -=-=-=-=-=-=-=-=-=-=-=-

配置 infer 相关依赖库

在终端中  使用 homebrew 安装 贼鸡儿方便

（1）brew install autoconf automake cmake opam pkg-config sqlite
10-20分钟  

（2）brew cask install java
10-20分钟  

（3） brew install infer
 （这里可能出现报错）

前俩安装需要翻墙。(手动狗头.jpg)

brew install infer 如果出现类似报错，进入read this 提示的页面中查看相关解决方法

报错：

到这，infer 算是安装完成了

4.使用infer 进行项目静态检测：

（1）单文件检测自己看说明很简单 ，这里不说了（点这里自己看🍻）

（2）项目检测坑有点多 ，遇见一堆问题

问题1：

Xcode: xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

解决办法：

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

github issues

问题2：

like
BUILD FAILED
Error backtrace:
Raised at file "integration/Driver.ml", line 297, characters 16-78
Called from file "integration/Driver.ml", line 176, characters 2-16
Called from file "backend/infer.ml", line 23, characters 2-36
Called from file "backend/infer.ml", line 106, characters 6-52
Uncaught error: ("InferModules__Driver.Infer_error("exited with code 65")")

解决办法：

infer --keep-going --no-xcpretty -- xcodebuild build -scheme HelloWorldApp -workspace HelloWorldApp.xcworkspace -configuration Debug -sdk iphoneos

这里用的是 infer 中的 examples，其中 HelloWorldApp 为 appName

infer --keep-going --no-xcpretty -- xcodebuild build -scheme appName -workspace appName.xcworkspace -configuration Debug -sdk iphoneos

infer --keep-going --no-xcpretty -- xcodebuild build -scheme laoyuegou -workspace laoyuegou.xcworkspace -configuration Debug -sdk iphoneos

项目扫描

cd infer-master/examples/ios_hello

infer --keep-going --no-xcpretty -- xcodebuild build -scheme HelloWorldApp -workspace HelloWorldApp.xcworkspace -configuration Debug -sdk iphoneos

根据工程文件大小扫描时长不等。

5、扫描结果

扫描结果路径：/Users/yindongbo/Downloads/infer-master/examples/ios_hello/infer-out/bugs.txt
