Re: A problem in Makefile

[ARPITA SAXENA]

Hi Henning,

    Yes, I feel something is missing .  Actually, there is a cvs repository on
the machine where this makefile 'Makefile_rm' lies . The path is represented by
the keyword 'CVSROOT' used in 'Makefile_rm' . This cvs export command brings a
copy of the specified file (either .h or .cpp ) from the cvs repository into my
working directory . Once the dependency files are in my working directory, the
compilation & thereafter linking is invoked . The command 'cvs update' will
only let me see the status of the files in my working directory ( status can be
M - modified, C - conflict, A - added, R - removed etc) .
    Now, Henning, can you please send me your feedback.
    I am attaching my makefile 'Makefile_rm' again.
