CEFPython3 Linux error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run wxpython.py

What is the expected output? What do you see instead?

The example page is expected, instead I get an empty window.

What version of the product are you using? On what operating system?

cefpython3-27.1-ubuntu1204-64bit-portable.zip
Unbuntu 12.10 64bit

Please provide any additional information below.

May be related to http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=10787, but 
from that post, it appears you were able to fix that problem.

Not sure where to start debugging this- here is the console output:

The "cefpython3-27.1-ubuntu1204-64bit-portable.zip" release is intended for
Ubuntu 12.04 only. Please make a build for Ubuntu 12.10 and let me know if
the problem still exists. The instructions for building are on the BuildOnLinux
wiki page.

I took a look at the logs again. The real error that caused an empty window
was that it couldn't launch the renderer process, it failed launching the
"subprocess" executable. I see that you're using the portable version. After
extracting it, you need to chmod the subprocess executable. Here is the error
from the logs:

    [0727/120811:ERROR:child_process_launcher.cc(326)] Failed to launch child process

After a second thought, I think that it should run fine on Ubuntu 12.10.

I've added such a note on the Download_CEF3_Linux wiki page:

    If you've downloaded portable zip, then you need to chmod the subprocess executable, otherwise you will see an empty window with an error in logs saying that it failed to launch child process.
