Re: [Aria-users] why robot.getVel() gets unmeaningfull value in MobileSim

[Matt LaFary <lafary@xxxxxxxxxxxxxxxx>]

So the AT is running Linux then?

And we compile with Visual Studio .net 2003, which is the reason you 
need to rebuild the libraries if you're using .net 2005.

What errors did you get on the compile?

Also using release mode to compile instead of debug may help.  If this 
is a new project you made you may also need to set the compiler to use 
the right runtime library.  That's in project settings, C/C++, code 
generation.  It should use "Multi Threaded Debug DLL" in debug mode, and 
"Multi Threaded DLL" in release mode.

Also if you're not using Aria 2.5.1 then you should grab that to use.

If you still get errors please paste them into an email so that we can 
help with them.
