$@ or address@hidden question

[Kovalevich Victor]

Hi.
I have a question: can I use automatic variables $@ or address@hidden in the dependency
of a rule ? When these variables are defined exactly: after then all the
dependencies of a rule are resolved or when the processing of a rule is started
?

Is the rule below correct?

CCC=gcc
CPPFLAGS=-DLINUX -UDEBUG -DNDEBUG -O0 -Winline -Wparentheses -c
SRCPATH=${HOME}/project/cpp/
OBJPATH=${HOME}/project/obj/
MAKEFILE=${HOME}/project/makefile

MODULES_CPP_1=module1.cpp module2.cpp module3.cpp
MODULES_CPP_1_O=${MODULES_CPP_1:%.cpp=${OBJPATH}%.o}

${MODULES_CPP_1_O}: ${SRCPATH:address@hidden:.o=.cpp}}  ${MAKEFILE}
    @ echo --- Compile address@hidden:.o=.cpp}'->'address@hidden
    @ ${CCC} ${CPPFLAGS}  -o $@ ${SRCPATH:address@hidden:.o=.cpp}}

I use GNU Make version 3.79.1, under linux:

I tried to use -p option. make printed following  information concerning
the rule above:

    @ echo --- Compile address@hidden:.o=.cpp}'->'address@hidden
    @ ${CCC} ${CPPFLAGS}  -o $@ ${SRCPATH:address@hidden:.o=.cpp}}

As I see $@ and address@hidden are not defined in the dependencies but are defined in
the action of a rule. Is it correct behaviour of the make or I ran into a
defect ?

Thanks in advance.
