[Playerstage-users] installation problem

[Hossain, Md.Z <zho...@ya...>]

Hi users,

I'm trying to install player-2.1.2 and getting error mentioned below. Actually 
I've to install version before 3.0.0 because my system is back dated and can't 
update and that's why i've to use ./configure(i can't use cmake in my onboard 
robot system). Help of yours will be appreciated.

Errors:

mica2.cc: In member function `int Mica2::DecodeSerial(unsigned char*, int)':
mica2.cc:1074: error: call of overloaded `log(short unsigned int&)' is 
   ambiguous

Subject: Re: [Playerstage-users] LMS200 laser spacial filtering

A much better approach would be a filtering driver. That way, it can be 
used on other devices with similar data (while not all ranger devices 
will use it, that doesn't mean only the lms200 will).

If you want to get really funky, make it capable of loading filtering 
plugins. :)
