[Playerstage-users] Configuring motor drivers...

[Brent B. <ou...@gm...>]

I've been trying to add my own driver that controls the motors on the
robots.  Before that, I am trying to get the exampledriver.cc to work.
 Do I need to use libtool to link it?  Is there a specific command to
do that, because I did make the .la file using libtool, but it still
gives me an error:

Parsing configuration file "example.cfg"
trying to load /usr/local/src/player/examples/plugins/exampledriver/./libexampledriver.la...success
invoking player_driver_init()...failed
error   : failed to resolve player_driver_init:
/usr/local/src/player/examples/plugins/exampledriver/./.libs/libexampledriver.so.0:
undefined symbol: player_driver_init

after I did this:
libtool --mode=compile g++ -g -O -c exampledriver.cc 
and this:
libtool --mode=link gcc -g -O -o libexampledriver.la exampledriver.cc
-rpath /usr/local/lib -lm

player_driver_init is still in the extern "C" function and I haven't
changed it a bit.  Is this supposed to fail (and the
player_driver_init is what I need to configure for my driver or is
that just in main)?  Since I prelinked the file with libtool, is this
conflicting with this function?  All I'm looking for is motor control,
so any pointers you guys could give (a newbie at best), I would
appreciate it.
