Error while giving gn gen command for building chromium

[Venkat Satish]

Hi,

HI All I am building the latest Chromium and webview apk on my ubuntu system. Below are the command that I usually follow:

2) mkdir Chromium_Webview_Clean

3) cd Chromium_Webview_Clean

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

5) export PATH="$PATH:/path/to/depot_tools"

6) mkdir Go_to_your_chromium_dir

7) cd Go_to_your_chromium_dir

8) fetch --nohooks android

9) cd src

10) git fetch --tags

11)git fetch origin my_stable_branch(example 72.0.3617.105 from https://omahaproxy.appspot.com/)

Loading https://omahaproxy.appspot.com/...

12)git checkout -b my_stable_branch FETCH_HEAD

13)gclient sync --with_branch_heads

14) sudo ./build/install-build-deps-android.sh

15)gclient runhooks

22)for Chromium

gn gen --args='target_os="android" target_cpu="arm64" android_channel="stable" is_debug=false is_component_build = false is_official_build=true is_chrome_branded=false use_official_google_api_keys=false enable_resource_whitelist_generation=true ffmpeg_branding="Chrome" proprietary_codecs=true enable_remoting=true' out/chromium_browser_arm64_85

23)autoninja -C out/chromium_browser_arm64_85 chrome_public_apk

after giving the command number 22 I am getting error:

ERROR at //build/config/compiler/pgo/BUILD.gn:115:23: Script returned non-zero exit code.

      pgo_data_path = exec_script("//tools/update_pgo_profiles.py",

solutions = [

  {

    "name": "src",

    # ...

    "custom_vars": {

      "checkout_pgo_profiles": True,

    },

  },

],

and then run "gclient runhooks" to download it. You can also simply disable the PGO optimizations by setting |chrome_pgo_phase = 0| in your GN arguments.

See //build/config/BUILDCONFIG.gn:351:3: which caused the file to be included.

  "//build/config/compiler/pgo:default_pgo_flags",

can anyone help on this?

Thanks,

Hi Venkat,

It's clear from the error message, please add ' chrome_pgo_phase = 0 ' to the args list. I hope you might have tried that already.

Thanks
