Yeah, I suspect also the same, since even main function reference wasn't found. x---------- main.o(.text+0x18):main.c undefined reference to '__main' x---------- I don't know what I have done wrong. I have already included the directory of std. header file during compiling, and also the library during linking. My makefile like this : X---------- CC = m68k-coff-gcc LD = m68k-coff-ld # Here located all the standard header files INC = c:/gcc-m68k/m68k-coff/include # Here located all the 'lib*.a' LIB = c:/gcc-m68k/m68k-coff/lib/m68000 CFLAGS = -m68000 -ansi -Wall -O2 -I$(INC) LDFLAGS = -s -n -Tmsdsl.ld -L$(LIB) PROG = crt0.o control.o extern.o gti_avm.o gti_be.o gti_cof.o gti_ipu.o \ gti_sas.o gti_tr.o gtidebug.o gtifram.o gtihip.o gtiinit.o \ gtiparam.o gtiram.o gtixcvr.o hdlc.o hic.o main.o malloc.o \ scc.o uart.o vers.o driver: msdsl.ld $(PROG) $(LD) $(LDFLAGS) -Map=driver.map -o driver.x $(PROG) crt0.o: crt0.S asm.h mc68302.h $(CC) $(CFLAGS) $< -c -o $@ ............... ............... ...............
