Question

Sorry about the confusing title, I had a hard time describing the problem.

I have two values available to me, the first one is a constant and the second one could be any number of folder levels

BASE = application/classes
FOLDERS = types/ads

Based on those, I need to run commands like the following (in that order):

verifyDir application/classes
verifyDir application/classes/types
verifyDir application/classes/types/ads

I could also just pass all the directories to verifyDir if that’s easier

verifyDir application/classes application/classes/types application/classes/types/ads

This is within a makefile, so using gmake’s functions is acceptable.

Please don’t answer with a suggestion to restructure what I am doing. It would take way too long to explain why I need this.

Answer 1

I’m not a gmake master, so I can just propose a way how to achieve that using shell, may be it helps you to achieve that in gnu make…

BASE=application/classes
FOLDERS=types/ads

verifyDir $BASE
NEWBASE=$BASE
for c in `echo $FOLDERS | tr "/" " "`; do
    NEWBASE="$NEWBASE/$c"
    verifyDir $NEWBASE
done
