Trying to Package Unity game in Ubuntu Linux debian

Question

I created a Unity game for Linux, and now I am trying to Package it in debian so that I can upload it afterwards to the Ubuntu Software Center. I have prepared everything and when I use this command debuild -d -us -uc , I get this error:

To help dpkg-shlibdeps find private libraries, you might need to use -l.

My rules file is this:

# -*- makefile -*-
# Sample debian/rules that uses debhelper.
# This file was originally written by Joey Hess and Craig Small.
# As a special exception, when this file is copied by dh-make into a

# This special exception was added by Craig Small in version 0.37 of dh-make.

# Uncomment this to turn on verbose mode.
#export DH_VERBOSE=1

    dh $@ 

Any Ideas to help me?

Apparently you are trying to build a package containing amd64 binaries on a i386 host system.

This is what confuse dh_shlibdeps .

If this is not a mistake and you really want to mix architectures in a single package, I guess your best solution would be to completely skip this step. You can do so by adding something like the following to your debian/rules:

override_dh_shlibdeps:
    @echo "Skipping dh_shlibdeps"

If you do that, you will have to manually fill your package dependencies in debian/control as they won't be autodetected.
