[SOLVED] Unable to build CEF 2840 on Ubuntu 16.04 64bit

[TheSHEEEP]

I am using the automated build script the following way:

python automate-git.py --download-dir=/home/thesheeep/git/cef --branch=2840

This is the error I get (last part of the output):

--> successfully patched ../content/browser/streams/stream_context.h
--> successfully patched ../content/public/browser/browser_context.h
--> successfully patched ../content/public/browser/storage_partition.h

Did you run Chromium's install-build-deps.sh script?

You can run `/home/thesheeep/git/cef/chromium/src/printing/cups_config_helper.py --api-version` manually to verify that you've resolved the error. Then re-run automate-git.py with the `--force-build` command-line flag.

[TheSHEEEP]

Did you run Chromium's install-build-deps.sh script?

I didn't. I just followed the wiki's "Automated Method" step. If more than that is needed, you should probably put it there

I ran it manually now, and it says:

ERROR: Only Ubuntu 12.04 (precise), 14.04 (trusty), 14.10 (utopic), 15.04 (vivid), 15.10 (wily) are currently supported.

Now that is a bummer. Not supporting new Ubuntu versions basically kills any purpose of this. Not going to build a product that will only allow me to support past OS versions
I modified the python file to allow 16.04 as well, it didn't produce any error, but it also didn't really seem to do anything at all.
Not sure if just adding the Ubuntu version to the top of the file is enough... it certainly didn't change anything about my errors.

You can run `/home/thesheeep/git/cef/chromium/src/printing/cups_config_helper.py --api-version` manually to verify that you've resolved the error.

Running the script manually results in this error:

python cups_config_helper.py --api-version
Traceback (most recent call last):
File "cups_config_helper.py", line 106, in <module>
sys.exit(main())

raise child_exception
OSError: [Errno 2] No such file or directory

Then re-run automate-git.py with the `--force-build` command-line flag.

I don't think this would do any good as long as the above error isn't fixed?

Thanks for pointing that out. I'll improve the docs.

You should use the install-build-deps.sh script (not .py). It seems to support Ubuntu 16.04. I have not tested it myself on that platform.

You can run `/home/thesheeep/git/cef/chromium/src/printing/cups_config_helper.py --api-version` manually to verify that you've resolved the error.

Running the script manually results in this error:

python cups_config_helper.py --api-version

Looks like you need to install the package that provides the `cups_config` utility.

[TheSHEEEP]

I made a fresh attempt, got the same error, this time I ran the install-build-deps.sh script manually* and then re-ran the script with "--force-build".

* Which worked, except for not being able to install the chromeos fonts, but whatever. I specified the --no-chromeos-fonts flag and it went through smoothly.

Hooray, more errors!
I am surprised this script seems to work for many people, while I get so many errors.
I'd be happy to use prebuilt libs, but they are not available for 2840, it seems.

[magreenblatt]

Run `sudo apt-get install libgtkglext1-dev`, then try automate-git.py again.

[Czarek]

2840 prebuilt binaries appeared on Spotify two days ago.

[TheSHEEEP]

Run `sudo apt-get install libgtkglext1-dev`, then try automate-git.py again.

Some progress, but ends in an error again:

This looks a bit like I need to do a fully fresh rebuild (--force-clean && --force-build didn't help), so I will do that and see what happens.

Also, good that prebuilt ones are now available, so I got something in case the manual approach fails.

[TheSHEEEP]

Hmmm, no.
Getting the same error, even after a completely fresh build procedure.

And there is no previous error in the output suggesting that something would be wrong.

Of course, I am on an x64 platform, but usually that wouldn't prevent building x86.
And it especially wouldn't prevent the creation of a folder...

This suggests that there's some file or directory named `out/Debug_GN_x86` that already exists, but the script can't access it. Try manually deleting the `/home/thesheeep/git/cef/chromium/src/out` directory.
