Interpreting Makefile to build library

Hello all;

I am curious if could give me pointers on how to use a makefile to interpret what components need to be included in a project in order to build a dll or exe.

The code is C code and I would like to build it into Windows dll.

This is from the Mpg123 source code.

Thanks in advance
RJ


CC=gcc
CFLAGS=-Wall -g -DLAYER1 -DLAYER2 -DLAYER3

all: mpglib


*.o: mpg123.h mpglib.h

mpglib: layer1.o layer2.o common.o dct64_i386.o decode_i386.o layer3.o tabinit.o interface.o main.o
      $(CC) -o mpglib \
            common.o dct64_i386.o decode_i386.o layer3.o \
            tabinit.o interface.o main.o layer2.o layer1.o -lm

clean:
      rm *.o mpglib

*.o: mpg123.h mpglib.h

mpglib: layer1.o layer2.o common.o dct64_i386.o decode_i386.o layer3.o tabinit.o interface.o main.o
    $(CC) -o mpglib \
         common.o dct64_i386.o decode_i386.o layer3.o \
         tabinit.o interface.o main.o layer2.o layer1.o -lm

clean:
    rm *.o mpglib

The rule for building mpglib is made dependant on the object files, which suggest that there are layer1.cpp layer2.cpp common.cpp dct64_i386.cpp decode_i386.cpp layer3.cpp tabinit.cpp interface.cpp and main.cpp (the extensions might be .cc, .C or .cxx though). I think you left out the rule that builds these .o files from the source files.
