Unable to build for hatch on stable or main

[Mitchell]

When I try main gclient sync freezes forever at "$ gclient sync

I also tried the latest stable 136.0.7103.142 and it seemed to require me to be a googler.

I would really like to be able to run and modify chromiumOS for my real chromebook.

Hello,

What you're doing is to build the Chromium Browser's chrome binary for ChromiumOS, which relies on the OS image and SDK.

We didn't build an external ChromiumOS image and SDK for hatch. Only limited boards are built for the external version of ChromiumOS.

If you would like to fully replace your stock ChromeOS to your customized built ChromiumOS, you can follow

https://www.chromium.org/chromium-os/developer-library/guides/development/developer-guide/

to build the full image of the OS and flash to your Chromebook.

You may lose user data stored on your device.

Building Chromium for ChromiumOS without SDK is not possible, and building full sets of SDK locally is not straightforward.

It consists of toolchains (compilers, linkers), ChromiumOS sysroot (for system libraries, etc), environment (for populating necessary Chromium build flags) that you'll have to build separately for each.

You can modify your Chromium browser, build and deploy within the ChromiumOS chroot, by using portage related commands (https://dev.gentoo.org/~zmedico/portage/doc/man/ebuild.1.html, https://wiki.gentoo.org/wiki/Full_manpages/emerge)

We have emerge-$BOARD and ebuild-$BOARD command in the chroot for each board.

Developer guide above also has information on how to modify and build a single package (and its dependencies).

Chromium browser is at chromeos-base/chromeos-chrome package.

You can then use cros deploy to deploy the built package only, instead of the whole OS, to your Chromebook.

Please checkout to the correct base ChromiumOS version before building from scratch since libraries, and IPC shared across browser and OS is not guaranteed to be 100% compatible across versions.

Regards,
