4.5.4 Linking and Assembling

For assembling you can use either GPUTILS' gpasm.exe or MPLAB's mpasmwin.exe. GPUTILS are available from http://sourceforge.net/projects/gputils. For linking you can use either GPUTILS' gplink or MPLAB's mplink.exe. If you use MPLAB and an interrupt function then the linker script file vectors section will need to be enlarged to link with mplink.

Here is a Makefile using GPUTILS:

.c.o: 
        sdcc -V -mpic14 -p16f877 -c $<  
 
$(PRJ).hex: $(OBJS)  
        gplink -m -s $(PRJ).lkr -o $(PRJ).hex $(OBJS) libsdcc.lib

Here is a Makefile using MPLAB:

.c.o:  
        sdcc -S -V -mpic14 -p16f877 $<  
        mpasmwin /q /o $*.asm 
 
$(PRJ).hex: $(OBJS)  
        mplink /v $(PRJ).lkr /m $(PRJ).map /o $(PRJ).hex $(OBJS) libsdcc.lib

Please note that indentations within a Makefile have to be done with a tabulator character.
