LinuxQuestions.org - Makefile: using targets to declare dependent vars

Hi, I need to write a Makefile to change IP address of some PC's

I was trying this approach:

Code:

SUBNET=192.168.0.



all : install



pc1 :

IP=1



pc2 :

IP=2



install :

    ifconfig eth0 $(SUBNET)$(IP)

and then call like this:

Code:

make pc1 install

to change ip address of pc1 to 192.168.0.1

But IP var always get the last value, here =2

Can anyone help me on this?

I also need to read some value like: tux21, tux22, tux23, etc and separate:

tux21 in tux, 2 and 1...
tux22 in tux, 2 and 2...
tux23 in tux, 2 and 3...

Can I use sed to do this? If so, how?

Thanks,
Bruno
