SDCC 3.0.0 won't link
When trying to build with SDCC I get this error:
sdcc -mpic16 -p18f2321 -I/usr/share/sdcc/non-free/include/pic16 -I/usr/share/sdcc/include/pic16 -I/home/andrew/projects/programming/Incubator/ -c Incubator.c -o obj/Release/Incubator.rel

SDCC : pic16/pic14 3.0.0 #6037 (Nov 7 2010) (Linux)
I can compile in a terminal by removing the '-c' and '-o' options and adding the '-L' options, so I believe the problem must be that sdcc won't function as a linker, which mode the second command implies.
I could be totally wrong on my analysis of this however, since this is the first time I've tried using SDCC, following the guide on the wiki.

History
SDCC < 3 used .rel as object file extension.
For SDCC >=3, this was changed to ".o", you have to change this in the advanced compiler options.
Don't forget the --use-non-free SDCC option for PIC compilation.

Great! That works.
In case anyone else has trouble finding it, the advanced compiler options are at: Settings -> Compiler and Debugger -> Other Options -> Advanced Options -> Others -> Object file extension
