which method is better for building deb package

kushalkoolwal · 01-26-2008, 04:34 PM

Hello,

Recently I was digging into compiling .deb packages from source debian packages i.e. from .dsc, .orig.tar.gz and .diff.gz.

I came across two methods to do this which are as follow:

Method1:

Code:

$ dpkg-source -x squid_2.6.1-3.dsc
$ cd squid-2.6.1/
$ fakeroot debian/rules binary

Methold2:

Code:

$ dpkg-source -x squid_2.6.1-3.dsc
$ cd squid-2.6.1/
debuild -uc -us

In short what is the difference when we give "fakeroot" and "debuild" command in the above two methods.

I thought that was what debhelper was for.

I apologize for not being able to understand your reply. Can you explain a bit further?

btw, "fakeroot" isn't a build command, it just lets you run debian/rules without becoming root.

Thank you for the reference. I think I came across that page before when I was searching but I was not sure if I understand the entire scenario correctly. Hence the question.

It seems that:

Code:

dpkg-buildpackage -rfakeroot

is the way to go.

Kind of depends on what you want. If you do a complete build, debuild will do it, it starts by running dpkg-buildpackage. See "man debuild"

Interestingly, I don't get anything when I type:

man debuild.

It says:

No Manual entry for debuild

I suppose you don't have devscripts installed then.

Yes you were right makuyl. Now I can see the man page....

kushalkoolwal · 01-31-2008, 07:58 PM

One last question hopefully...

I read the man pages for debuild and now I am confused regarding the difference between the following two commands:

debuild -rfakeroot
and
dpkg-buildpackages -rfakeroot

Thanks

debuild lets you automate stuff, like adding gpg signatures you've saved in /etc/devscripts.conf or ~/.devscripts.
Also debuild lets you validate package with lintian after running dpkg-buildpackages, see: http://www.debian-administration.org/articles/336
