前言

理論上這是一個(gè)很好的想法斧抱，但真正落實(shí)到實(shí)踐常拓，簡(jiǎn)直坑的不要不要的！筆者最終在CentOS上實(shí)在搞不動(dòng)了辉浦，只在Ubuntu上弄了弄抬，關(guān)鍵CentOS是公司環(huán)境也不敢太造次。

整個(gè)東西寫出來(lái)主要是讓自己記住坑太多宪郊，不是實(shí)在想不開(kāi)沒(méi)事干掂恕，千萬(wàn)不要再搞。

思路來(lái)源https://github.com/facebook/xcbuild/issues/37

目的

做這個(gè)事情起初只是因?yàn)槲宜静惶峁㎝ac機(jī)器來(lái)做自動(dòng)打包弛槐，但又想要讓我做自動(dòng)打包懊亡，能提供的也只有CentOS系統(tǒng)，不過(guò)很快就發(fā)現(xiàn)打包其實(shí)完全不可能丐黄，因?yàn)樽C書問(wèn)題很難解決斋配，然后想著跑跑CI的test也不錯(cuò)才繼續(xù)研究了一下。。艰争。坏瞄。畢竟我們Model都是自動(dòng)生成的，git提交后跑一下CI確保能各端運(yùn)行正常還是很有用的甩卓，另外版本歸檔打tag的時(shí)候跑一下CocoaPods把完整可執(zhí)行代碼構(gòu)建好拉下來(lái)歸檔也是挺不錯(cuò)的鸠匀！

現(xiàn)實(shí)是恐怕就CocoaPods構(gòu)建是比較穩(wěn)定100%沒(méi)問(wèn)題，編譯這個(gè)完全不敢說(shuō)ok逾柿。缀棍。。所以有條件的話還是建議用有臺(tái)Mac專門來(lái)干這些事机错，不然實(shí)在太麻煩爬范，哪怕ssh到一臺(tái)同事電腦悄悄開(kāi)個(gè)賬戶搞都比在linux上搞靠譜！

如圖實(shí)現(xiàn)弱匪，沒(méi)mac和有mac簡(jiǎn)直就是天壤之別的惡心差距青瀑！

安裝配置

準(zhǔn)備工作

ruby （為了支持CocoaPods）
clang 4.0或以上（為了支持IOS10，如果你準(zhǔn)備的sdk版本不高萧诫，那就無(wú)所謂了斥难，關(guān)鍵是對(duì)應(yīng)上）
Apple clang(用他的話妥妥的手動(dòng)apt-get拯救不了你)
cctools-port 生成ios工具鏈（ios-toolchain）回頭替換掉Xcode里的
ninja
xcbuild
Xcode（確切的說(shuō)其實(shí)只要三個(gè)文件夾但我很不放心用了整個(gè)）

CocoaPods 安裝

這里不得不提CocoaPods兼容性真心不錯(cuò)
CentOS

sudo yum install ruby
sudo gem install cocoapods

Ubuntu

sudo apt-get install ruby
sudo gem install cocoapods

就是如此簡(jiǎn)單！已經(jīng)時(shí)可用狀態(tài)了帘饶！

Clang 安裝

接下來(lái)就不細(xì)說(shuō)CentOS了應(yīng)為基本上大部分庫(kù)都是要源碼安裝哑诊。。及刻。
首先clang --version看看版本是不是自己想要镀裤，多半都不是然后直接刪了

sudo apt-get autoremove clang

然后搞一下軟件源/etc/apt/sources.list不然各種依賴包各種找不到讓你爽歪歪

下面大更新一波，安裝

sudo apt-get update
sudo apt-get install git gcc cmake libssl-dev libtool autoconf automake clang-4.0

除了錯(cuò)誤別找我缴饭，直接谷歌去找源
安裝完clang看看位置如果不是usr/bin
執(zhí)行下面命令制作軟鏈接淹禾，只為保險(xiǎn)不是必需的。茴扁。。汪疮。

sudo ln -s /usr/bin/clang-4.0 /usr/bin/clang
sudo ln -s /usr/bin/clang++-4.0 /usr/bin/clang++

吐槽一波CentOS你更新了源也沒(méi)用該沒(méi)有的還是沒(méi)有建議直接源碼安裝峭火。

#下載llvm源碼

Apple Clang 安裝

步驟如上面CentOS源碼安裝Clang差不多智嚷，只是把Clang地址改了下

wget https://opensource.apple.com/tarballs/clang/clang-800.0.42.1.tar.gz
tar xf clang-800.0.42.1.tar.gz
cd clang-800.0.42.1/src

Apple Clang的src文件夾下和llvm的目錄結(jié)構(gòu)一樣然后仿照之前操作即可

cctools-port 制作ios-toolchain 的Clang

ios sdk 打包

下載完Xcode直接執(zhí)行下面命令

SDK=$(ls -l Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs | grep " -> iPhoneOS.sdk" | head -n1 | awk '{print $9}')
cp -r Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk /tmp/$SDK 1>/dev/null
cp -r Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1 /tmp/$SDK/usr/include/c++ 1>/dev/null
pushd /tmp
tar -cvzf $SDK.tar.gz $SDK
rm -rf $SDK
mv $SDK.tar.gz ~
popd

制作 iOS armv7 工具鏈

cd cctools-port
IPHONEOS_DEPLOYMENT_TARGET=5.0 usage_examples/ios_toolchain/build.sh ~/iPhoneOS10.0.sdk.tar.gz armv7

制作工具鏈成功后會(huì)提示*** all done ***

將生成的工具鏈移到 /usr/local/ 目錄并更名為 ios-armv7

sudo mv usage_examples/ios_toolchain/target /usr/local/ios-armv7

將庫(kù)文件拷貝一份卖丸，放進(jìn)公共庫(kù) /usr/lib

sudo cp /usr/local/ios-armv7/lib/libtapi.so /usr/lib

最后將工具鏈的 bin 目錄加入PATH，方便調(diào)用

export PATH=$PATH:/usr/local/ios-armv7/bin

制作 iOS arm64 工具鏈

cd cctools-port
IPHONEOS_DEPLOYMENT_TARGET=5.0 usage_examples/ios_toolchain/build.sh ~/iPhoneOS10.0.sdk.tar.gz arm64

制作工具鏈成功后會(huì)提示*** all done ***

將生成的工具鏈 /usr/local/ 目錄并更名為 ios-arm64

sudo mv usage_examples/ios_toolchain/target /usr/local/ios-arm64

使用 rename 命令重命名前綴以與 armv7 區(qū)分開(kāi)來(lái)把 arm- 前綴改為 aarch64- 前綴

rename 's/arm-/aarch64-/' /usr/local/ios-arm64/bin/*
sudo rm /usr/local/ios-arm64/aarch64-apple-darwin11-clang++
sudo ln -s /usr/local/ios-arm64/aarch64-apple-darwin11-clang /usr/local/ios-arm64/aarch64-apple-darwin11-clang++

將庫(kù)文件拷貝一份盏道，放進(jìn)公共庫(kù) /usr/lib

sudo cp /usr/local/ios-arm64/lib/libtapi.so /usr/lib

最后將工具鏈的 bin 目錄加入PATH稍浆，方便調(diào)用

export PATH=$PATH:/usr/local/ios-arm64/bin

其實(shí)到這基本完活了，單跑.m文件已經(jīng)沒(méi)問(wèn)題了，下面只是為了更加方便的編譯項(xiàng)目

這里已經(jīng)可以跑個(gè)測(cè)試程序編譯試試了如arrch-apple-darwin11-clang helloworld.c -o helloworld或arm-apple-darwin11-clang helloworld.c -o helloworld

合并 armv7 和 arm64 工具鏈(可選)

一般用ar命令做合并不過(guò)容易出問(wèn)題

替換xctoolchain

把最后想要用的生成的工具鏈clang 和 clang++文件替換到usr/bin下（不替換也可以達(dá)成目的即可）衅枫，相當(dāng)于回頭編譯的時(shí)候走我們產(chǎn)出的這套clang環(huán)境嫁艇。總之就是思路就是讓xcbuild走我們的這套clang去打包編譯程序即可弦撩。如果你用Apple Clang或直接Clang能打包編譯也就不用自己手動(dòng)做這個(gè)事了步咪。

Ninja 安裝

Ubuntu一行命令解決。益楼。猾漫。。

apt-get install ninja-build

CentOS天坑模式開(kāi)啟不出意外先升級(jí)cmake
源碼安裝最新版cmake解壓執(zhí)行./bootstrap && make && make install 就ok了感凤，3個(gè)命令合一悯周。
然后下載ninja源碼

git clone git://github.com/ninja-build/ninja.git && cd ninja
git checkout release
./configure.py --bootstrap

最后把Path加一下

export PATH=$PATH:/xxx/xxx/ninja

xcbuild 安裝

git clone https://github.com/facebook/xcbuild
cd xcbuild
git submodule update --init
make

最后把Path加一下和DEVELOPER_DIR
DEVELOPER_DIR就是Xcode的目錄，Xcode其實(shí)只需要有三個(gè)文件夾Xcode.app/Contents/PlugIns陪竿，Xcode.app/Contents/Developer/Toolchains,Xcode.app/Contents/Developer/Platforms

export PATH=$PATH:/xxx/xxx/xcbuild/build
export DEVELOPER_DIR=/xxx/xxx/Xcode.app

使用

完全可以像在Mac下一樣用沒(méi)有任何區(qū)別禽翼，不過(guò)也就CocoaPods完全ok，xcbuild指令和xcodebuild用法完全一樣直接用xcodebuild也沒(méi)問(wèn)題萨惑，只不過(guò)能不能編譯成功就聽(tīng)天由命吧捐康！坑很深，慎入庸蔼！
