Question Question about creating targets in makefile

Hi,

I have a question related to makefile. I'm new to makefile and I'm in the process of writing a makefile for my RBT build. I have multiple source files and when I compile them I will get multiple object files (one object file for each source file). I'm having problem in creating a target for each object file with out hardcoding the object file names. I read the list of source file names from another make file. Assume the variable SRC_NAMES contains list of source file names (say test1.c test2.c test3.c). Now I want to create target for each objects for it (say test1.obj test2.obj test3.obj). Currently I have written some thing like below,

Code:
 
#############################################
OBJS_LIST := $(foreach file,$(SRC_NAMES),$(notdir ${file}))
OBJS_LIST := $(DSP_COMMON_OBJ_LIST:.c=.obj)
 
all: final.exe
 
final.exe: $(OBJS_LIST)
   create exe here
 
$(OBJS_LIST): $(SRC_NAMES)
    compile and generate object file for each source files here.
 
#############################################

This is not working. Since OBJS_LIST contains many object names, compilation action is repeated for many times for the target $(OBJS_LIST). My question is how to split the obj target into multiple targets without hard-coding the target obj names?

Thanks,
Anand

NAME
nbp_name - NBP name parsing SYNOPSIS
nbp_name( name, obj, type, zone ) char *name, **obj, **type, **zone; DESCRIPTION
nbp_name() parses user supplied names into their component object, type, and zone. obj, type, and zone should be passed by reference, and should point to the caller's default values. nbp_name() will change the pointers to the parsed-out values. name is of the form object:type@zone, where each of object, :type, and @zone replace obj, type, and zone, respectively. type must be proceeded by `:', and zone must be preceded by `@'. EXAMPLE
The argument of afpd(8)'s -n option is parsed with nbp_name(). The default value of obj is the first component of the machine's hostname (as returned by gethostbyname(3)). The default value of type is ``AFPServer'', and of zone is ``*'', the default zone. To cause afpd to register itself in some zone other than the default, one would invoke it as afpd -n @some-other-zone obj and type would retain their default values. BUGS
obj, type, and zone return pointers into static area which may be over-written on each call. netatalk 1.3 12 Jan 1994 NBP_NAME(3)
