#233 0.22.1 undefined symbol with xorg 1.11.4/kubuntu 12.04 lts

[Jason]

The xf86-input-wacom-0.22.1 release tarball compiles ok on kubuntu 12.04 (xorg version 1.11.4) and X initially loads using it. However as soon as a tablet is attached to the machine and X tries to configure it the Xserver crashes reporting the error;

/usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/input/wacom_drv.so: undefined symbol: input_option_menu

This problem isn't present in previous releases 0.20 and 0.21.

Let me know if you need any further information on the matter.

Thanks
Jason

p.s. and before anybody asks, sorry no I can't just update to a later kubuntu release; I'm dealing with a corporate desktop where we are locked into staying on each long term release (lts) until the next one comes out.

[Peter Hutterer]

input_option_menu?? that doesn't sound right, please re-check the symbol name

[Jason]

Sorry my apologies, I'm not quite sure how I copied the entire message carefully and still messed up the most important bit; The correct error is usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/input/wacom_drv.so: undefined symbol: input_option_new

I've also attached a picture of the error just incase there is something else I've typed wrong and missed. I couldn't get the message from the log file, even though the X process goes away when the error occurs the actual error isn't logged in the Xorg log, it just gets to;

then logging cuts off, I had to startx from a terminal and get the output there to see the symbol lookup error.

[Peter Hutterer]

This is a Ubuntu bug. 12.04 shipped with what we called the frankenserver. they have a lot of backports from 1.12, but not everything. The wacom driver has a ifdef guards in place to supply input_option_new() on older servers but the ubuntu backport screws that check.

[ 2440.961] ABI class: X.Org XInput driver, version 16.0

this should report version 14.0 on server 1.11. You can work around this locally in wcmValidate.c, just remove the ifdef around input_option_new. either way, that's a Ubuntu bug, sorry.

[Jason]

hmm I've tried applying the attached patch to my source which should cover commenting out the ifdefs around that statement. However the result from compiling with that patch for me is just a X segfault as soon as the tablet is attached;

[Peter Hutterer]

that was indeed a driver bug - now fixed with cb14924a2a5be21c8525ca70932ab8b5f0f99752. Thanks

[Jason]

Thanks for the quick patch, I can confirm that the driver is now working with my Xorg version and has been stable for several hours now. :)

[Peter Hutterer]

sorry, typo, should report ABI version 13 (not 14 as in the previous comment, and definitely not 16 as the 12.04 X server)
