Hello
I have a problem to define variable assignment per target.
Requirements:
all_targets = target1 target2
for target1 set variable a = val1
for target2 set variable a = val2
all_target:
call $@ a .....
In make manual chapter "Target-specific Variable values" I found:
There is one more special feature of target-specific variables: when
you define a target-specific variable, that variable value is also in effect
for all prerequisites of this target (unless those prerequisites override it
with their own target-specific variable value). So, for example, a statement
like this:
prog : CFLAGS = -g
prog : prog.o foo.o bar.o
will set CFLAGS to `-g' in the command script for `prog', but it
will also set CFLAGS to `-g' in the command scripts that create `prog.o',
`foo.o', and `bar.o', and any command scripts which create their
prerequisites.
I think This is what I need. But When I tried to implement it I got an error
message " no rule for CFLAGS needed for target prog"
I will appriciate your help:
Where did I wrong? Why does make treat CFLAG as depend, instead variable
assignment?
Thanks in advance
