Question

我正在尝试从铬源构建无头示例作为C ++库

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

G:\chromium\src\headless>gn gen  --args=is_debug=true --root=../ ../out/test
Done. Made 10741 targets from 1804 files in 21901ms
G:\chromium\src\headless>ninja -C ../out/test headless_example
ninja: Entering directory `../out/test'
[24577/24577] LINK headless_example.exe headless_example.exe.pdb

G:\chromium\src\headless>

构建后，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

gn gen --ide = vs2017 --filters =“ // headless” out \ Headless
忍者-C out \ Headless headless_example

构建6小时后

cd out / Headless
./ headless_example.exe

我也遇到同样的错误。

但是我成功构建并运行了chromedriver

我的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.

use_ozone = true
ozone_auto_platforms = false
ozone_platform = "headless"
ozone_platform_headless = true

# Embed resource.pak into binary to simplify deployment.
headless_use_embedded_resources = true

# Expose headless bindings for freetype library bundled with Chromium.
headless_fontconfig_utils = true

# Remove a dependency on a system fontconfig library.
use_bundled_fontconfig = true

# In order to simplify deployment we build ICU data file
# into binary.
icu_use_data_file = false

# Use embedded data instead external files for headless in order
# to simplify deployment.
v8_use_external_startup_data = false

enable_nacl = false
enable_print_preview = false
enable_remoting = false
use_alsa = false
use_cups = false

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

您在上方输入的gn gen命令不正确。请尝试以下命令：

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