Hi Reiner,

        - created backend_src/obj by hand

        - added automated_scanner.o by hand
        - added the required library by hand


You're free to publish broken stuff on the web and refuse to fix it and
other people are as free to ignore the project if even the most simple
bugs never get fixed."

Please, let us be civilised.

What is the problem? You know, I am not the packager; I only coded and
tested the compiled executables. Please note, that I compiled my
executables by directly invoking gcc and by using the Lazarus IDE for
the frontend. This means, the way I compile both executables cannot
uncover bugs related with using dpkg-buildpackage or make.

       "- created backend_src/obj by hand
        - created backend_src/bin by hand"


Tell, what is missing in my source tree? Should I create the obj and
bin directories myself in the source tree? You know, there were
opinions which argued against that. Also note, I am not at all
refusing anything that I know how to handle.

Please, be specific as to what is missing in netman?

To All:
At the moment I a very busy somewhere else. I cannot dedicate as
before whole days for coding. Now, I only afford an hour or so. I can
only say, that since its inception, which is around the middle of last
August, I have been continually using netman as my network manager.


Thanks, Edward.
