Question about simple gmake Makefile

[jose luis fernandez diaz]

Hi,


VAR=hello
VAR=$(subst hello,bye,$(VAR ))

print:
echo $(VAR)


sqocfms01:jdiaz :tmp>make print
Makefile:6: *** Recursive variable `VAR' references itself (eventually). Stop.



VAR=hello
VAR:=$(subst hello,bye,$(VAR ))
^
print:
echo $(VAR)

sqocfms01:jdiaz :tmp>make print
echo bye
bye


Why the first Makefile is wrong ?

Thanks,
Jose Luis.
