Code: Select all

ninja -C out/Debug_GN_x64 cef chrome_sandbox

, but at end I am getting out of memory error as below. I am having 32 GB RAM server.

What OS? What GN_DEFINES?

We are using cef 102 already. we are just upgrading it with same process we followed for cef 102 and 100,92 and all. but for 104 upgrade getting this error.

OS- ubuntu 20
GN_DEFINES=is_official_build=true\ proprietary_codecs=true\ ffmpeg_branding="Chrome"\ use_pulseaudio=true

[magreenblatt]

Try the recommended GN_DEFINES: https://bitbucket.org/chromiumembedded/ ... figuration

With recommended GN_DEFINES I do not get any error. but when I use GN_DEFINES as per project requirement then it fails with "out of memory" error. Below are the GN_DEFINES we use (update.sh).

Code: Select all

update.sh
#!/bin/bash
export GN_DEFINES=is_official_build=true\ proprietary_codecs=true\ ffmpeg_branding="Chrome"\ use_pulseaudio=true
python3 ../automate/automate-git.py --download-dir=/home/maint/code/chromium_git --depot-tools-dir=/home/maint/code/depot_tools --force-update --no-distrib --no-build --branch=5112

and create.sh as below.

Code: Select all

 create.sh
#!/bin/bash
export GN_DEFINES=is_official_build=true\ proprietary_codecs=true\ ffmpeg_branding="Chrome"\ use_pulseaudio=true\ use_gnome_keyring=false\ use_vaapi=false
./cef_create_projects.sh

I have tried build with 60 GB RAM, 24 CPU, also 8GB swap but still getting out of memory error.
And if I use recommended GN_DEFINES build is successful on a machine with 32GB RAM 8CPU and 2GB swap.

Can you please check if there is any issue with the GN_DEFINES that I am using. As the same GN_DEFINES worked for cef 102, 92 and previous versions.

Is there any change in GN_DEFINES required to build cef-104 and 105 ?
