This looks very simple .. somehow I cant figure it out ..
Gnu make manual speficies that a rule of type :
bigoutput littleoutput : text.g
generate text.g -$(subst output,,$@) > $@
is same as :
bigoutput : text.g
generate text.g -big > bigoutput
littleoutput : text.g
generate text.g -little > littleoutput
I have a simple make with one rule that says :
a.o b.o : a.c
When I execute this make all I get is
Reading makefiles...
Reading makefile `Make10'...
Updating goal targets....
Considering target file `a.o'.
File `a.o' does not exist.
Considering target file `a.c'.
Finished prerequisites of target file `a.c'.
No need to remake target `a.c'.
Pruning file `a.c'.
Finished prerequisites of target file `a.o'.
Must remake target `a.o'.
cc -c -o a.o a.c
Successfully remade target file `a.o'.
Is there a reason why target b.o is considered by make ?

Sharan
