Declaring a global variable through a MakeFile

[Joe Mesa]

Hi,

I have been trying to set the PATH environment variable through a
MakeFile with no luck. To explain more PATH already is set to its
value outside the MakeFile. In order to use the gnu executables I have
to place the gnu directory before the Windows directory in the PATH.
I can do this easily in a .bat or .login but I was trying to do it
within the
MakeFile. So I wrote:

TOOLSDIR=$(shell cd ../../tools/gnu; pwd)
TMPPATH=$(TOOLSDIR):$(PATH)
PATH=$(TMPPATH)
export PATH

and I get the following error:
*** Recursive variable `PATH' references itself (eventually). Stop

Is there a way to do what I am trying or do I have to use a .bat or
.login
to accomplish what I want?

Thanks,
Joe

Use := (simple assignment) instead of = (recursive assignment).

PATH := $(TMPPATH)

See the GNU make manual for a discussion of the differences.
