Bug Description

Looks like there been a few reports before about similar stuff: here is the fix..

Problem sane trying to load libhpmud.so

open("/lib/tls/i686/cmov/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/tls/i686/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/tls/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/i686/cmov/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/i686/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/tls/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/i686/cmov/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/i686/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/sse2/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/lib/i486-linux-gnu/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/i486-linux-gnu/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory)

Package hplip only has
/usr/lib/libhpmud.so.0.0.4 and the link
/usr/lib/libhpmud.so.0

I know ldconf should take car of this but it doesn't (wrong coding of library creation)
Hence the following is needed...
root@yourlinuxbox:/usr/lib# ln -s libhpmud.so.0.0.4 libhpmud.so

Scanning now works like charm...

Cheers Dyna

I should have reported it here. The issue is specific Ubuntu, not the upstream code.

Can confirm this for Ubuntu Jaunty.
Scanning with HP LaserJet M1522nf was failing until the creation of symbolic link
sudo /bin/ln -s /usr/lib/libhpmud.so.0 /usr/lib/libhpmud.so

This should be handled by the package installer.

I can confirm this happening on Karmic.

One thought, though... The scanner driver was added by a script that warned me about installing a propietary plugin, so I don't know if the bug might lie within the plugin manager (or whatever it is).
