    That's exactly how you do that. (That's how it will look when you get $(OBJS) working properly, too.)

    I meant to say that the code is still not compiling like :

    gcc -o PROG1 PROG1.c PROG2.c PROG3.c -L /usr/orasys/9.2.0.6/lib -lclntsh -m64

    and if I try to compile the PROG2.c separately it also fails...it does not have any dependency.

    Run objdump on your objects to verify that they are 64-bit. Run objdump on the Oracle client library to verify that it is 64-bit.

    The original ELFCLASS64 message was reported for the client library, so the client library is 64-bit. The conflict must be with your stuff.

    If the client library is 64-bit, and your objects are 64-bit, then I suspect you may have a bad installation of gcc which is not linking the correct runtime, or the wrong copy of crt1.o or some such thing.
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}

    For this purpose the "file" command would probably also work.
