uClinux makefile

Altera_Forum · ‎02-04-2007

Does anyone know how to create a makefile for a uClinux project consisting several .c and .h files. I am having trouble linking any function to "main"which are not in the same .c file(but in the same application project folder).

For example I am getting an error:

*******************************

mpeg2enc.bin(.text+0xf0): In function `main':

/cygdrive/c/Anika/uc/strx1/sw/mpg/mpeg2enc.c:70: undefined reference to `putseq'

******************************

putseq is another .c file which is in the same application project but not in the same file(mpeg2enc.c-> main).

Right now my makefile looks like this:

**********************************# # configurable options# - set DEBUG = 1 to turn on debugging support#

DEBUG = 1

PROJ_NAME = mpg

INSTALL_DIR = ./build

PROGS := mpeg2enc.exe

OBJ = mpeg2enc.o conform.o putseq.o putpic.o puthdr.o putmpg.o putvlc.o putbits.o motion.o predict.o readpic.o writepic.o transfrm.o fdctref.o idct.o quantize.o ratectl.o stats.o

LIBCDIR := C:\Altera5\kits\bin\eclipse\plugins\com.microtronix.nios2linux.uClibc_1.4.0

UTILSDIR := C:\Altera5\kits\bin\eclipse\plugins\com.microtronix.nios2linux.application_1.4.0

CFLAGS +=

# # You should not need to modify anything beyond this point#

TOPDIR = ./

include Rules.mak

ifeq '$(DEBUG)' '1'

PROGS += $(PROGS:.exe=.gdb)

endif

all: $(PROGS)

clean:

rm -f *.o *% core mpeg2encode

mpeg2enc.exe: mpeg2encode

coff2exe mpeg2enc

mpeg2encode: $(OBJ)

$(CFLAGS) -o mpeg2encode $(OBJ) -lm

conform.o : conform.c config.h global.h mpeg2enc.h

fdctref.o : fdctref.c config.h

idct.o : idct.c config.h

motion.o : motion.c config.h global.h mpeg2enc.h

mpeg2enc.o : mpeg2enc.c config.h global.h mpeg2enc.h

predict.o : predict.c config.h global.h mpeg2enc.h

putbits.o : putbits.c config.h

puthdr.o : puthdr.c config.h global.h mpeg2enc.h

putmpg.o : putmpg.c config.h global.h mpeg2enc.h

putpic.o : putpic.c config.h global.h mpeg2enc.h

putseq.o : putseq.c config.h global.h mpeg2enc.h

putvlc.o : putvlc.c config.h global.h mpeg2enc.h vlc.h

quantize.o : quantize.c config.h global.h mpeg2enc.h

ratectl.o : ratectl.c config.h global.h mpeg2enc.h

readpic.o : readpic.c config.h global.h mpeg2enc.h

stats.o : stats.c config.h global.h mpeg2enc.h

transfrm.o : transfrm.c config.h global.h mpeg2enc.h

writepic.o : writepic.c config.h global.h mpeg2enc.h

***********************************************

I'll really appreciate if someone could help me in this regard.

You'd better move to Linux PC and follow the nios wiki.

It will be easier to port apps.

Thanks for the suggestion. Unfortunately, at this moment it is not possible to have uClinux on linux PC's at Ryerson. My code is working perfect just on Nios II IDE(without uClinux) though, because I think Nios II IDE uses it's own makefile, where as for uClinux I need to create a makefile.

So any other suggestion how to create the makefile for my app project(consists of several .c and .h files) in uClinux?
