help creating a makefile that shows my current ip address

[gabi]

Hi.

I am a newbie when it comes to make.

I am trying to create a simple Makefile that will echo the IP address as
part of the line, in order to tell me what command to pass to uBoot after
I compile my program.

I want make to generate output like this:
> set serverip 192.168.1.171

where "set serverip " is a simple string and the actual IP address is
returned from a command like the following:

> ifconfig | sed -n '/192\.168\.1\./p' | cut -c -33 |cut -c 21


I am using the ubuntu 9.04 included make:
> make --version
> GNU Make 3.81

When I tried the above ifconfig command as part of the Makefile I got an
error.

Initially I used this command:
------------- Makefile -------------------------------------------
severip := $(shell ifconfig | sed -n '/192\.168\.1\./p' | cut -c -33 |cut
-c 21)

all:
    @echo -n "set serverip "
    @echo $(serverip)
-------------- Makefile end---------------------------------------

It complained about
/bin/sh: Syntax error: "(" unexpected
make: *** [all] Error 2


So I have simplified my Makefile to look like this:

------------- Makefile -------------------------------------------
severip := $(shell ifconfig)

all:
    @echo $(serverip)
-------------- Makefile end---------------------------------------

or this:

------------- Makefile -------------------------------------------
severip := $(shell /sbin/ifconfig)

all:
    @echo $(serverip)
-------------- Makefile end---------------------------------------


I still get this error:
/bin/sh: Syntax error: "(" unexpected
make: *** [all] Error 2

I do not know what to do to get passed this.

Any help would be appreciated,
Thank you,
