参考了多个教程。

新手折腾了几天,虽然成功编译了lib，还没测试用过,可能有错误,记录一下,希望见谅。

1.准备环境:

git 工具 :https://git-scm.com/download/win

java(re) 8:https://www.java.com/zh-CN/download/

python3.9(从windows store):https://apps.microsoft.com/store/detail/python-39/9P7QFQMJRFP7?hl=zh-cn&gl=cn&rtc=1

skia源码:https://github.com/google/skia.git

depot_tools:https://chromium.googlesource.com/chromium/tools/depot_tools.git

bazel(bazel...windows-x86_64.exe):https://github.com/bazelbuild/bazel/releases

更改文件名 bazel...windows-x86_64.exe 到 bazel.exe

2.拉取第三方库

git clone  https://github.com/google/skia.git   

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

3.配置环境变量

(在变量";"号后添加目录)

JAVA_HOME=jre

CLASSPATH=%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;

PATH %JAVA_HOME%\bin

PATH depot_tools

PATH bazel

4.同步 tools

cd skia

python tools/git-sync-deps

5.编译

设置 skia\gn\BUILDCONFIG.gn :

  win_sdk = "C:/Program Files (x86)/Windows Kits/10"
  win_sdk_version = "10.0.17763.0"

  win_vc = "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC"
  win_toolchain_version = "14.16.27023"

生成项目:

bin\gn gen out\Static_x86 --args="is_official_build=false is_debug=false target_cpu=\"x86\"" --ide="vs2017" 

修改项目下toolchain.ninja文件:

删除:cmd.exe /c C:/Program Files (x86)/Windows Kits/10/bin/SetEnv.cmd /x86 &&

复制 msobj140.dll、mspdb140.dll、mspdbcore.dll

从 C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x64

到 项目目录。

 如出现错误:sktarray.h C2398: 元素“2”: 从“const uint32_t”转换到“int”需要收缩转换，可添加转换类型符号:

 使用编译命令:

ninja -C out/Static_x86
