telegram不知多少次的重编译

鼎鼎大名的telegram，前后不知道编译几次了，虽然都成功了，一是基本编译完就相当于看完源码😂，二是也没有记录编译的过程，部分内容是重复的。
看自己这次能走到哪里，希望比编译完成走的远一点。
隔天上午终于编译成功了，这次不会随便升级系统和xcode了。

环境

big sur 11.1
xcode 12.3
telegram v7.2
buck version 47bf9aaad4fe33fd913f62737f7e581454f80b01

JAVA 11以及版本切换
BUCK 安装使用
WatchMan 安装
Telegram 源码下载及编译
1. 生成 Telegram_Buck.xcworkspace
2. 打开生成的 workspace 然后 build

JAVA 11以及版本切换

使用 homebrew 安装 openjdk

添加到brew
brew tap adoptopenjdk/openjdk
查看jdk版本
brew search jdk

install

brew cask install adoptopenjdk8     ##Install JDK 8`
brew cask install adoptopenjdk9     ##Install JDK 9  
brew cask install adoptopenjdk10    ##Install JDK 10  
brew cask install adoptopenjdk11    ##Install JDK 11  
brew cask install adoptopenjdk12    ##Install JDK 12  
brew cask install adoptopenjdk13    ##Install JDK 13  
brew cask install adoptopenjdk14    ##Install JDK 14  
brew cask install adoptopenjdk15    ##Install JDK 15

查看当前 java 版本

查看当前已安装的java版本

$ /usr/libexec/java_home -V

 /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home

准备切换脚本，放到当前shell配置文件里，用的 zsh，放在 ~/.zshrc

export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_11_HOME=$(/usr/libexec/java_home -v11)
alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java11='export JAVA_HOME=$JAVA_11_HOME'

生效配置文件及切换版本

$source ~/.zshrc
$java8 #切换到 8
$java11 #切换到 11

BUCK 安装使用

到目前为止2021-01-14，使用 homebrew 安装 BUCK 都是失败的。
搜索发现可以使用直接预编译好的版本。

Addepar currently maintains a Java 11 / Python2 fork of Buck: avalible buck link. This might be helpful.

下载这个版本，然后 chmod 755 buck.pex 就可以直接执行了。
之前是使用 buck 现在直接用 buck.pex 比较麻烦的是带上下载地址的路径，因为没有安装到系统路径，所以需要指定路径比如 ~/Downloads/buck.pex

WatchMan 安装

这个还是简单的，使用 homebrew 直接搞定。

$brew update
$brew install watchman

Telegram 源码下载及编译

可以指定版本下载，这次使用的是 7.2

git clone --recursive --branch release-7.2  https://github.com/TelegramMessenger/Telegram-iOS.git
cd telegram-ios

下载完成后，开始编译。
参考经典的两个链接 #219 和 Build and Run Telegram-iOS v7.2 in Xcode 12.x Simulator

生成 `Telegram_Buck.xcworkspace`

mozjpeg 修改, Inside third-party/mozjpeg/BUCK, it declares two targets of arm64 andarmv7. We can change armv7 to x86_64 as we don’t need armv7 in Simulator and on most devices.

webrtc-ios 修改。

Telegram-iOS builds its video calls upon webrtc-ios, which is a gigantic module imported this year. It’s supposed to be built to a framework by buck before generating workspace files. Unfortunately, the code in the official repo doesn’t compile with Xcode 12.x and doesn’t support thex86_64 target.

The first change is on a python script find_sdk.py which is a part of webrtc-ios build system. It helps to locate the SDK path in Xcode.app. The original regular expression ^MacOSX(10.\d+).sdk$ doesn’t work against Xcode 12.x, as the SDK pathname has been changed to Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk. We need to change the expression to ^MacOSX(1[01].\d+).sdk$, which matches both MacOSX10 and MacOSX11 SDK names.

生成 workspace file make project

打开生成的 workspace 然后 build

编译的时候会遇到这个问题，主要是 pointerInteraction.swift 导致的，这里提供一个改正好的文件内容，提供参考，主要是注释掉相关语句。
