I've taken over someone else's project code which uses #defines to select
which region the code is being compiled for.  Instead of hard-coding these
#defines, i would like to edit the makefile to specify the region at compile
time.

ie. I would like to be able to enter "make USA" or "make Mexico" and have
that automatically define REG_UNITED STATES or REG_MEXICO when compiling.

I've tried to check the MAKECMDGOALS variable, but I still get a "No rule to
make target "USA". Stop" error.

my makefile currently is:

I'm new to gcc and am running Mandrake Linux 8.1 with gcc 2.96-0.62mdk.

I've been experimenting with writing my own makefiles and have run into
a problem.  The makefiles work OK as long as all of the source code is
in the same subdirectory, however, if the source is in another
subdirectory, the makefile can't find it.  Here's a simple code sample:

-------------------------------------------------
CC = gcc

all: simple

vpath %.h ~/Projects/test/src

simple.o: simple.c 
	$(CC) -c simple.c

simple: simple.o
	$(CC) -o simple simple.o
-------------------------------------------------------

The source code is in the /Projects/test subdirectory but simple.c has a
header file called foo.h that's in the /Projects/test/src subdirectory. 
The error message is "No such file or directory called foo.h".  Why
isn't it being found?  VPATH= ~/Projects/test/src doesn't work either.

What's missing?

TIA

Rich

hi,
 
in the makefile i want to change the working 
directory itself. and further commands should be run from that directory. is it 
possible }
 
for eg.
 
#pwd is c:/tmp
chdir c:/tmp/test
 
cc 
test.c        # the test.c file exists in the 
c:/tmp/test directory.
 
 
any idea how to do this ?
 
 
thanks in advance,
 
mahadev
