WinAVR error on N&V Balance Bot

[Ronbot]

Hello,
I recently started building the Balance Bot from the N&V december 2006 issue. I used the latest version of WinAVR to compile the software with the supplied make file. The compilation seems to go well at first be stops with an "error 1" message, just as it is busy with ".elf" files. I see lots of .o file that seem okay but no Hex. It means that I am stuck since I am a newby to AVR (i am a PIC man myself)

Anybody out there who has succesfully compiled the software from the N&V site or has run into the same problem ?

Any help appreciated.

Ron
