如何为 ARM 交叉编译 Chromium？

Question

目标

我需要在mini210s运行Linux 3.0.8 armv7l 的FriendlyARM上安装 Chromium

环境

• 带有 Ubuntu Precise64 的 Vagrant 盒子
• depot_tools按照这些指南安装获取代码和 Linux Chromium ARM

工具链 depot_tools

得到后depot_tools：

vagrant@vagrant:~/depot_tools$ fetch chromium

环境变量

export GYP_CROSSCOMPILE=1
export GYP_DEFINES="target_arch=arm arm_float_abi=hard"

依赖关系

vagrant@vagrant:~/depot_tools/src$  ./chrome/installer/linux/sysroot_scripts/install-debian.wheezy.sysroot.py --arch=arm 
Installing Debian Wheezy arm root image: /home/vagrant/depot_tools/src/chrome/installer/linux/debian_wheezy_arm-sysroot
Downloading http://storage.googleapis.com/chrome-linux-sysroot/toolchain/285950/debian_wheezy_arm_sysroot.tgz

build/install-build-deps.sh --arm
build/install-build-deps-android.sh
gclient sync

编译

build/gyp_chromium -Goutput_dir=out_arm 
ninja -C out_arm/Debug chrome

错误

期待一些建议和线索

按照eyoung100 的说明，仍然出现错误，但进一步

clang=False失败时在 Precise64 上

使用时chromium.gyp_env（无环境变量）

vagrant@vagrant:/vagrant_data/buildhost/src$ more ../chromium.gyp_env 
{ 'GYP_DEFINES': 'target_arch=arm arm_float_abi=hard component=shared_library linux_use_gold_flags=1 clang=False', 'GYP_CROSSCOMPILE': 'True', }

我明白了

Answer 1

现在我在工作，我会一步一步地写一个答案。首先，您似乎以错误的顺序执行这些步骤。因此，我将按照应执行的顺序对这些步骤进行编号。

1. mkdir -pv ~/chromium
2. cd ~/chromium
3. git config --global user.name “Joel Maranhao”
4. git config --global user.email “youremail@example.com”
5. git config --global core.autocrlf false
6. git config --global core.filemode false
7. git config --global color.ui true
8. git clone https://chromium.googlesource.com/chromium/tools/depot_tools
9. export PATH=$PATH:~/chromium/depot_tools 请参阅更新说明 1
10. mkdir -v ~/chromium/buildhost 请参阅更新说明 2
11. cd ../buildhost 请参阅更新说明 2
12. fetch --nohooks chromium
13. cd src && ./build/install-build-deps.sh 见注 3
14. sudo apt-get install gcc-arm-linux-gnueabihf
15. sudo apt-get install g++-4.8-multilib-arm-linux-gnueabihf
16. ./build/install-build-deps.sh --arm 见注 3
17. gclient sync
18. GYP_CROSSCOMPILE=1 GYP_DEFINES=target_arch=arm arm_float_abi=hard component=shared_library linux_use_gold_flags=1 见注 4
19. gclient runhooks
20. ninja -C out/Debug chrome

注意步骤 17 - 19。步骤 18 替换了文件chromium.gyp_env 中来自方法2 的导出语句（这有效地将构建编译器切换到了clang）。第 19 步导入 Chromium.gyp_env 设置，并将以正确的顺序运行正确的构建脚本。

警告：测试步骤

我将在我的 XUbuntu VM 上测试这些步骤并报告/更新等。

更新说明

1. PATH如果您要多次执行此操作，建议对变量进行永久更改。找到以下内容：

# set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi

在$HOME\.profile。添加 PATH=$PATH:~/chromium/depot_tools，以便最终if看起来像：

# set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" PATH=$PATH:~/chromium/depot_tools fi

如果需要，创建一个$HOME/bin目录（它在我的 VM 上不存在），然后注销并重新登录。

2. 从 Studying your Post 中，在从存储库下载 Gigs 和 Gigs 数据时，我看到您运行了fetch脚本并将源代码下载到depot_tools目录中。这是一个常见的错误，很容易通过创建一个单独的目录来纠正，就像我所做的那样。这使管理和操作构建文件所需的工具与您正在构建的项目分开。这也确保您正在构建的项目不会被用于构建它们的工具污染。
3. build-deps.sh无论是否交叉编译，第一遍都会下载所有构建工具。如果脚本抱怨 Held Packages，则需要执行第 14 步和第 15 步。2nd Pass(Step 16)，设置交叉编译。随着构建的进行，我将更新此注释。
4. 出于某种原因，OP 和我都在处理gyp_env文件时遇到了问题。因此，我更新了第 18 步以包含所需的导出。如果有兴趣使用该gyp_env文件，请参阅Gyp 用户文档、配置构建和通用 Gyp 构建参数
