Hi

Thank you for the reply and the pth to TIE implementation ...

The reason I did not send PRF is cause I think the problem has nothing
to do with platform/compiler

Does your reply effectively mean, that I cannot use TAO using multiple
inheritance and the only approach is using TIE methodology?

Also I am integrating a CORBA component into an old existing project.
It already has a make file and I have to modify it for idl
dependencies. So I shall not be using mpc to create a make file. Is
there a sample for writing make by simply using ACE macro files
include directly and not using MPC?

Please find PRF below. I am aware it is a comercial license but prefer
to use this channel as it is more for my curosity.

    TAO VERSION: 1.3a_p10

    HOST MACHINE and OPERATING SYSTEM:
        If on Windows based OS's, which version of WINSOCK do you
        use?: SunOS szur0747dap 5.8 Generic_117350-35 sun4u sparc
SUNW,Netra-T12


    TARGET MACHINE and OPERATING SYSTEM, if different from HOST:
    COMPILER NAME AND VERSION (AND PATCHLEVEL):

    AREA/CLASS/EXAMPLE AFFECTED:
[What example failed?  What module failed to compile?]

    DOES THE PROBLEM AFFECT:
        COMPILATION? Yes
            If so, what do your $ACE_ROOT/ace/config.h and
            $ACE_ROOT/include/makeinclude/platform_macros.GNU contain?
        LINKING?
            On Unix systems, did you run make realclean first?
        EXECUTION?
        OTHER (please specify)?
[Please indicate whether ACE/TAO, your application, or both are
affected.]

    SYNOPSIS:
1.  Do I have option to use multiple inheritance using TAO? If yes,
how do I compile a Impl file derived from BaseImpl and POA_Derived*
2.  How to create a makefile manually without having to use mpc

    DESCRIPTION:
[Detailed description of problem.  Don't just say "<blah>
doesn't work, here's a fix," explain what your program does
to get to the <blah> state. ]

    REPEAT BY:
[What you did to get the error; include test program or session
transcript if at all possible.  ]

    SAMPLE FIX/WORKAROUND:
