Thread: How to Modify Makefile to Build a Map File

Hi all,
I have a C makefile that I would like to modify such that it produces a mapfile in addition to the regular exe and bin files. I've been googling around but it's still not 100% clear on where and the exact syntax to use. If anyone can look at this Makefile (attached) and suggest what to try, that would be great.

Thanks!
Will

The meat and potatoes of the build process is right here:

Code:

# rule to build executable
$(EXEC): $(COBJ) $(SOBJ) $(LDSCRIPT)
        @echo $@
        @..\BuildTools\buildver.bat >$(dir $(EXEC))version.c
        @$(CC) $(RTOSPORT) $(CFLAGS) $(subst +,$(SPACE),$(INCLUDES:%=-I%)) \
                $(dir $(EXEC))version.c $(CCOUT)$(dir $(EXEC))version.$(OBJEXT)
        @$(LD) $(LDFLAGS) $(LDOUT)$(EXEC) $(SOBJ) $(COBJ) $(dir $(EXEC))version.$(OBJEXT) $(LDFLAGS2)

There isn't some magic makefile command to produce a map file. It will depend on what compiler you're using, for which you should be able to find the documentation on how to generate map files. All I can tell you is that you probably need to add a line like this somewhere in the snippet above:

Code:

        @command_to_produce_map_file $(INPUT_FILES_FOR_MAP)
