The .debs do have other files, at least one. See the code I pointed at.
I don't make them with the usual tools,
for an eaiser potential cross build story -- fewer dependencies.
It worked at the time.

If it is a true .deb you need to apply > ar x xy.deband then> tar -xvJ <~/aux/data.tar.xz
(A real  .deb will also contain a control .tar.gz with control, shlibs, md5sums, postinst, etc.)
It should be built with> pushd BUILD> dpkg-buildpackage -sa -kmy at email.org> popdand checked with> lintian -EvIL +pedantic my.dsc

Am 28.05.2014 um 08:42 schrieb Jay K:.deb is just a .tar.gz or .tar.bz2 or .tar.xz with a little bit more around it.
They can be fancy but ours is not, it is just a compressed .tar.
Can you just crack it open and install the underlying parts?
It is likely "position independent" and you can extract it anywhere in your file system -- /usr/local/cm3, $HOME/cm3, etc.

I build them pretty "manually" see here:
the function MakeDebianPackage
Ok, it is an actually an "ar" file, and inside the main thing is data.tar with some compression like .gz or .xz.

It looks like it is external to cm3 anything. But maybe .deb is incorrect in some subtle way.

Lintian check results for /home/bruce/Downloads/cm3-LINUXLIBC6-REL.deb:
Can't use an undefined value as an ARRAY reference at /usr/share/perl5/
Lintian/Collect/Package.pm line 513, <$_[...]> line 7562.

Is this a Perl issue or an installer issue?
