(...) Rudolf, I'm not the one to answer your question, but I can tell you this: You need to provide the list of unresolved references before anyone can help you. Unresolved references are typically because not all files are identified in the (...) (20 years ago, 23-Sep-04, to lugnet.robotics.rcx.legos)

Hello everybody, I downloaded the source files of BrickOS and tried to build them. During the compiling process there are no errors, but during the linking process over 270 errors are appearing.

  Re: OS X Complier problems solved--now struggling with BrickOS
 
(...) I got brickos working on a windows box (no joy with either gentoo linux on a PC or winXP on Virtual PC for my Mac).

  Re: How to turn LEDs on/off ?
 
(...) I was not referring to the IR LED. I was referring to LEDs that can be connected to one of the motor ports. I believe Ross' initial response gave me the information I need. Thanks for everyone's help. -Brian (20 years ago, 10-Aug-04, to lugnet.robotics.rcx.legos)
 
  Re: How to turn LEDs on/off ?
