Hi ,
I am new to gcc and shell commands. I am trying to compile my code using gcc
3.3.2 provided with AMD Au1550 development CD. When I compile my code, I get an
error message with undefined references to printf and other file i/o functions.
I saw a couple of emails in the forum with the same problem.But, I think I have
problem with the makefile I am using. I never wrote a make file before and I am
using the makefile from the hello World example given with Au1550 CD. It works
for that example, but it crashes with my code.
I am attching the makefile with this email..
# Program name
NAME = test
# Endian
ifndef ENDIAN
ENDIAN = EL
endif
# Tool-chain used for compilation of code
# Win32 Cygwin toolchain
TOOLCHAIN = cygwin
# Monta Vista Hard Hat Linux toolchain
#TOOLCHAIN = hhl
ifeq ($(TOOLCHAIN),cygwin)
TOOLSDIR = /usr/local/comp/mips-elf/gcc-3.3.2
AS = $(TOOLSDIR)/bin/mips-elf-as
CC = $(TOOLSDIR)/bin/mips-elf-gcc -fno-builtin
LD = $(TOOLSDIR)/bin/mips-elf-ld
OD = $(TOOLSDIR)/bin/mips-elf-objdump
OC = $(TOOLSDIR)/bin/mips-elf-objcopy
#STRIP = $(TOOLSDIR)/bin/mips-elf-strip
endif
ifeq ($(TOOLCHAIN),hhl)
TOOLSDIR = /opt/hardhat/devkit/mips/fp_le
AS = $(TOOLSDIR)/bin/mips_fp_le-as
CC = $(TOOLSDIR)/bin/mips_fp_le-gcc -fno-pic -mno-abicalls

#STRIP = $(TOOLSDIR)/bin/mips_fp_le-strip
endif
RM = rm -f

#
# Files to compile
#
OBJS = \

#
# Rule for making
#
all: $(OBJS)
$(LD) -$(ENDIAN) -T test.ld -G 0 $(OBJS) -o $(NAME).elf
$(OD) -D $(NAME).elf > $(NAME).dis
$(OC) -O srec $(NAME).elf $(NAME).rec
clean:
$(RM) *.o
$(RM) *.dis
$(RM) *.rec
$(RM) *.elf
$(RM) *~
I got the linnker directive from the hello world example.I assume the problem
is with the linker and with the test.ld file from the hello world example.
I used SDE toolchain before with the same code ,but a different make file but I
never got this problem before.
I really need help on this immediately.
Thanks in advance - Pati
