Xpra doesn't start on CentOS 5

[ahuillet]

Hello,

Traceback (most recent call last):
  File "/usr/bin/xpra", line 6, in ?
    xpra.scripts.main.main(__file__, sys.argv)
  File "/usr/lib64/python2.4/site-packages/xpra/scripts/main.py", line 263, in main
  File "/usr/lib64/python2.4/site-packages/xpra/scripts/server.py", line 256, in run_server
AttributeError: 'module' object has no attribute 'fchmod'

This is with Python 2.4.3.

If this is enough to fix it, I can re-spin the CentOS 5 packages:

This makes it go further... but it crashes later:

[Antoine Martin]

The python-uuid module was meant to be pulled in as a dependency, see %define requires_extra , python-uuid

If not, we will need to deal with that too, but installing it by hand should fix that. Not sure about the segfault though...

[Antoine Martin]

Got it, the static build section was overriding EL5 options, fixed in r768

Re-spinning the packages now.

[ahuillet]

Better - but not solved. I think you need to add python-ctypes as a dependency.

[Antoine Martin]

Yes, I'll add ptthon-ctypes as a dependency for centos 5.x only and re-spin the packages, does this prevent the segfault ?
Or is there another issue still?

[ahuillet]

It prevents the segfault, however I still get something strange:

glib is missing, cannot set the application name, please install glib's python bindings: No module named glib

And I can't find the name of the package I'm supposed to install!

[Antoine Martin]

You can safely ignore this one, centos 5 is so outdated you just can't get the glib bindings for it, afaik.

[Antoine Martin]

new CentOS 5.x packages have the fix from r769 - please confirm and close this ticket.

[Antoine Martin]

works for me - closing

[ahuillet]

Sorry for not closing earlier. I confirm that it works.
