makefile: not "all" are made

hey, I must forget the syntax and got this strange phenomenon. In my makefile, I have

IB.a:errorcode.cpp EClientSocketBase.cpp EPosixClientSocket.cpp Myewrapper.cpp

all: test1 IB.a

and when I "make all", only test1 is made. I "make IB.a", and it says nothing to be done for it, though there is no IB.a under the dir at all!

What's wrong?

Where are you rules for the IB.a target? make doesn't magically know how to turn .cpp files into a .a file.
