Re-calculate variable values

[Aditya Kher]

folks,

I would like to re-evaluate or rather re-calculate variable value during making of target

 

something like below:

 

%gmake all RUN_COUNT=4

 

 

Makefile:

all:

   ${MAKE} run${RUN_COUNT}

 

#add code for

#    1. RUN_COUNT = RUN_COUNT -1

#     2. re-evaluate "all" target after updating RUN_COUNT pre-requisite

 

%.txt:

       touch ${RUN_COUNT}.txt

 

run%:%.txt

       @ls $^

 

thanks!
