Re: [Playerstage-developers] Player Error: Couldn't Find Driver

[Tim A. <ta...@en...>]

No I'm not calling Register() from Init().  I'm doing it pretty much exactly
as your example driver does:

_______ Snippet from walker_player.cc_____

CDevice* Walker_Init(char* interface, ConfigFile* cf, int section)
{
  if(strcmp(interface, PLAYER_POSITION_STRING))
  {
    PLAYER_ERROR1("driver \"walker_player\" does not support interface "
                  "\"%s\"\n", interface);
    return(NULL);
  }
  else
    return((CDevice*)(new Walker(interface, cf, section)));
}

Thanks for the speedy reply,
