Details:
01..ASDF := global
02..
03..${T2}%: private ASDF :=
04..
05.. A: private ASDF += A1
06..${T1}B: private ASDF += B1
07..${T1}C: private ASDF += C1
08..
09..${T1}C: private ASDF += C2
10..${T1}B: private ASDF += B2
11..${T1}A: private ASDF += A2
12..
13..A:B
14..B:C
15..
16..A B C:
17.. @echo "${@}: ${ASDF}"
To test this:
# Comment out lines 3 & 6-11; this will demonstrate how private variables
should behave
gmake T1='#' T2='#'
C: global
B: global
A: global A1 A2
# Comment out just line 3; this will demonstrate the problem; targets B & C
inherit changes from things that depend on them.
C: global A1 A2 B1 B2 C1 C2
B: global A1 A2 B1 B2
A: global A1 A2
# Don't comment out any lines; adding a pattern rule to wipe out ASDF for all
targets is a reasonable work-around until this problem gets fixed:
gmake
C: global C1 C2
B: global B1 B2
A: global A1 A2
