Hi,
When I run gn (with and without arguments) I get the same error.
Is there an option to set configuration manually?
pi@raspberrypi:~/v8 $ gn args
Traceback (most recent call last):
File "/home/pi/depot_tools/gn.py", line 38, in <module>
sys.exit(main(sys.argv))
File "/home/pi/depot_tools/gn.py", line 33, in main
return subprocess.call([gn_path] + args[1:])
File "/usr/lib/python2.7/subprocess.py", line 522, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child
raise child_exception
OSError: [Errno 8] Exec format error
