DPMSDisable bug is back

SDL Development
1

Hello all,

I’ve recently upgraded to Ubuntu 7.04 and all my SDL apps now fail with
this:

Failed loading DPMSDisable: /usr/lib/libX11.so.6: undefined symbol:
DPMSDisable

Things used to work with Ubuntu 6.10 and I haven’t changed hardware so I’m
not sure what’s gone wrong.
Any ideas?

Cheers,
K.

Is this an SDL you built, or one shipped with Ubuntu? What version of
SDL is this?

I believe this is fixed in Subversion revision #2523, which should be in
SDL 1.2.11:

http://www.libsdl.org/cgi/viewvc.cgi?view=rev&revision=2523

But I could be wrong…the fix changes the error message you saw, so
it’s likely you don’t have the fix.

I’ve got the following packages installed:

libsdl1.2debian (which is 1.2.11-7ubuntu1)
libsdl1.2debian-alsa (which is 1.2.11-7ubuntu1)
libsdl1.2dev (which is 1.2.11-7ubuntu1)

libsdl-image1.2-dev (which is 1.2.5-2)
libsdl-mixer1.2-dev (which is 1.2.6.1build1)
libsdl-ttd2.0-dev (which is 2.0.8-3build1)

I’m guessing the fix hasn’t made it to the debian packages you get from
synaptic (?)

I’ve got the following packages installed:

libsdl1.2debian (which is 1.2.11-7ubuntu1)
libsdl1.2debian-alsa (which is 1.2.11-7ubuntu1)

Is one of those a virtual package? The “-alsa” thing was because Debian
was working around various optional dependencies, but the latest SDL can
dynamically load everything and only needs a base package now…just
make sure you don’t have two SDLs installed through the package manager,
I guess.

Also, make sure it’s not using some older version of the library that’s
unexpectedly on your system (in /usr/local or whatnot), and then we’ll
follow up with Ubuntu if needed…I’m almost certain you can’t get that
error message and be using a real 1.2.11 build.
