[Sugar-devel] Bug 1240354 - SoaS live x86_64 20150706 does not login from live system user

[James Cameron]

The errors complain of missing symbols;

- sugar_event_controller_get_state

- acme_volume_alsa_new

Which were both added after 0.98.

On my F18 test systems, the package sugar-toolkit-0.98 brings in a
_sugarext.so file in /usr/lib/python2.7/site-packages/sugar/ which
does not have these symbols.

If this file were being used instead, then the outcome may be as
reported.

Is the package present?

If so, does removing the .so file fix the problem?

Use of the file could also be verified with strace -e open.

The line number is different.

@All, what is main.py and where are lines 1818 and 2637?

src/jarabe/main.py is much smaller, only 425 lines.

Some other diagnosis methods to suggest:

a.  in a fresh python process, try the relevant imports, e.g.

    from jarabe.view import gesturehandler
    from jarabe.model.sound import sound

b.  verify a symlink is present from /usr/lib/libsugarext.so.0 to
    libsugarext.so.0.0.0 (or equivalent functionality, as this is a
    guess from my experience with F18),

c.  use strings to check libsugarext.so.0, see if
    sugar_event_controller_get_state is present,

    strings /usr/lib/libsugarext.so.0 | \
        grep sugar_event_controller_get_state
