Java makefile help

Hi all,

I'm new to make files . I'm writing a make file to compile and create .so files. i've 20 .cpp files. I want to compile one file at a time and then i've to create 1 .so for each file that i compiled.

for eg:

list.mk is having all the 20 .spp files.

name = a.cpp
name =+ b.cpp
....

if i give CC -o $(name) it is taking all the 20 at the same time. but i want to take one file at a time and compile it.

simply if i give
display:
@echo " Name = $(name) "

then it has to display
Name = a.cpp
Name = b.cpp etc..
not like Name = a.cpp b.cpp c.cpp n all..


Thanks in advance

make help

here are some hints
->you have to use wildcard function, and you could use patsubs, subs and other patern manipulating functions
->here is a like for gnu make pdf http://www.gnu.org/software/make/manual/make.pdf

->you have to use
$(wildcard *.c)
$(patsubst %.c,%.o,$(wildcard *.c))

but i recomend to read the pdf, because make is worth learning for software engineers working on unix

makefile help

You might wish to investigate the automake tools also.
for a quick and dirty makefile, something like the following may help

Code:
CFLAGS=-ansi -O3 -Wall -Werror -ggdb 
CC=g++
AR=ar
INCLUDES=
LIBS=
MYLIB=testme.a
OBJECTS=file1.o file2.o version.o
OTHER=testme.h  makefile
 
.cpp.o: $(OTHER)
    $(CC) $(CFLAGS) -c $<
 
all : $(MYLIB) testlib
 
$(MYLIB) : $(OBJECTS) $(OTHER) 
    $(AR) -rvs $(MYLIB) $(OBJECTS)
 
testlib : main.cpp $(MYLIB)
    $(CC) -o testlib main.cpp $(MYLIB)
 
.phoney:
clean:
    rm -f $(MYLIB)
    rm -f *.o
    rm -f *.orig
    rm -f tags
    rm -f *~
    rm -f testlib
