本文关键字：浏览器 构建      更新时间：2023-10-16

我正在尝试构建无头示例作为C++

铬库 
https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md#usage-as-a-c_library

G:chromiumsrcheadless>gn gen  --args=is_debug=true --root=../ ../out/test
Done. Made 10741 targets from 1804 files in 21901ms

ninja: Entering directory `../out/test'
[24577/24577] LINK headless_example.exe headless_example.exe.pdb

Aftre build，我正在尝试启动headless_example.exe但出现错误

如何构建和运行headless_example？

更新

我的步骤

  1. gn gen --ide=vs2017 --filters="//headless" out\Headless
  2. 忍者 -C 出\无头headless_example

建造6小时后

  1. 光盘输出/无头
  2. ./headless_example.exe

我得到同样的错误。

但我成功地构建并运行了chromedriver

My Debug/args.gn

./out/Debug/args.gn

# GN args template for the Headless Chrome library
#
# Add import to arg.gn in out directory and run gn gen on the directory to use.
# E.g. for out directory out/foo:
# echo 'import("//build/args/headless.gn")' > out/foo/args.gn
# gn gen out/foo
#
# Use gn args to add your own build preference args.

>gn gen  --args=is_debug=true --root=../ ../out/test

您输入的上述gn gen命令不正确。请改为尝试以下命令：

>cp ../build/args/headless.gn out/Debug/args.gn
>gn gen --root=../ ../out/test
>ninja -C ../out/test headless_example
