Chrome API keys in the Chromium OS SDK chroot
When building Chromium on Chromium OS, there are (at least) 3 environments for building that are relevant.
- The host home directory.
- The home directory in the chroot.
- The home directory while building the chromeos-base/chromeos-chrome package.
The mechanism for compiling API keys into the Chromium binary itself under Chromium OS uses copy-propagation between the layers.
The enter chroot functionality takes care of propagating the keys. If the file
.googleapikeys is not present in the chroot, or is empty, the keys are
searched for in your home directory, extracted and written there. It is a
line-oriented file that should look like the sample in the chrome page.
'google_api_key': 'ABC123', 'google_default_client_id': '123/abc', 'google_default_client_secret': 'floor-sweeper',
To reset these the easiest way to update the chroot is simply:
cros_sdk -- rm ../../../.googleapikeys
and then the next time something enters the chroot, your native credentials will be copied in. If the keys are not working, try taking a look at the file to see if the format of your keys outside the chroot confused the propagation.
If you want your chroot to build something non-default or non-shared, you can
enter the chroot and change the
The chromeos-base/chromeos-chrome ebuild takes care of respecting the keys in
.googleapikeys in the final source build environment. It does this
by expanding and converting the file into an include.gypi in the inside
environment that does chromium's make.
