How can an external library be linked to a C programm with "make"?

[firelex]

Hello, all!
I'm a newbie in make.
My trouble is: I have a library (in an [tt]*.a[/tt] file) and want be able to use it's functions. How can I bind this lib to my programm? I thought it goes with [tt]make[/tt] somehow. I know it should be done with [tt]-l[/tt] option of make. BUT! The Makefile isn't mine I doing the reverse programming here and it isn't funny any more.

Here is a part of the Makefile:
[tt]
include ../Makefile.inc

DEST = libcommon.a
OBJS = utils.o debug.o fault.o

GLINFOBJS = globinfo.o ../infod/infod_clnt.o ../infod/infod_xdr.o

###

.PHONY: all install clean veryclean depend

all: $(DEST) libglobinfo.a

install: all

clean:
rm -f *.o *~

veryclean: clean
rm -f libcommon.a libglobinfo.a libtcl_gdbm.a

###

$(DEST): $(OBJS)
ar r $@ $(OBJS)

libglobinfo.a: $(GLINFOBJS)
ar r $@ $(GLINFOBJS)
[/tt]
The file, where I need some functions of that external lib is globinfo.c. I don't understand at all where should I put that [tt]-l[/tt] thing? In [tt]Makefile.inc[/tt]
are given the compiler things like

[tt]
CC = gcc -pipe

INCLUDES = -I/usr/X11R6/include -I/usr/include/xyz -I../common -I../rpc

DEFINES = -D_GNU_SOURCE -D_REENTRANT
ifndef OPTIMIZE
DEFINES += -D_DEBUG
endif

CFLAGS = $(INCLUDES) $(DEFINES)

CFLAGS += -mpentium -O -g -Wall #-Wno-implicit
LDFLAGS = -g

LIBPATH = -L/usr/X11R6/lib -L../common -L../rpc
.............
[/tt]

Any ideas?
Thanks.

I'm no prgrammer but you would propbably need to put it in either the CFLAGS or LDFLAGS variable.

Find the line where it actually compiles (gcc -something) and look at that line to figure it out.

You need to modify the

LIBPATH

line, adding the directory where your .a files (probably statically compiled libraries) are at. That's how it's done with 'gcc'. -L <your lib paths>, -I <your include paths>.
