[Playerstage-users] Custom Plugin: loading problem

[Garagoth <gar...@gm...>]

Hi,

I'm having problem using own plugin. It is not being loaded despite many
attempts and config variables.
Could you please point what I am missing?

**** Here is real.cfg file:

unit_length "m" # length units in meters
unit_angle  "degrees" # Angles in degrees

driver
(
    plugin "libqsilver"
    name "qsilver"
    controller_ids [ 7 8 ]
    provides ["7:::position1d:0"
              "8:::position1d:1"
             ]
    alwayson 1
)

**** Here is console output:

garagoth@development:~/UGV/Stage$ player real.cfg

So, file exists, all libs are resolved... what is wrong?
I tried using lib name without path (plugin "libqsilver") and I made sure it
is in plugin search path (was in current dir, just next to real.cfg file)
and results are the same.

Marcin.
