Build (backport) an newer Ubuntu package to run on an older Ubuntu version

[edeca]

I am trying to backport ircd-hybrid, which works fine using simply

$ prevu ircd-hybrid

However I would like to enable SSL, too, so I tried the following:

$ USE_OPENSSL="1" prevu ircd-hybrid

This does not work though, giving the following error:

dpkg-checkbuilddeps
dpkg-checkbuilddeps: Unmet build dependencies: libssl-dev
make: *** [configure-stamp] Error 1

I have libssl-dev installed on the actual machine so I assume that this is a problem within the build environment. No version numbers are mentioned so I assume that any version would do.

Is it possible to tell prevu to install the dependency inside the build environment? Or is there another problem that I have missed?

Thanks!

To tell a build dependency to install, you must unpack the source archive for your package, edit debian/control, and add the name of the package to the Build-Depends: list.

Thanks for this, that makes it build fine. I used apt-get source ircd-hybrid, edited debian/control then ran USE_OPENSSL="1" prevu in the build directory. The compile goes fine, but then this error occurs:

dpkg-deb: building package `ircd-hybrid' in `../ircd-hybrid_7.2.2.dfsg.1-2~6.06prevu1.ssl1_i386.deb'.
 dpkg-genchanges
dpkg-genchanges: error: cannot open .dsc file ../ircd-hybrid_7.2.2.dfsg.1-2~6.06prevu1.ssl1.dsc: No such file or directory

Is there anything that can be done to fix this?

Thanks.

I tried to backport libnfnetlink from Feisty but it failed to build a debian package:

 /usr/bin/install -c -m 644 libnfnetlink.pc /var/cache/prevu/src/20898/libnfnetlink-0.0.16/debian/tmp/usr/lib/pkgconfig/libnfnetlink.pc

Any idea, why it fails?

If us people out in user land are able to build successful backported packages, would it be possible to upload them to a central location somewhere so others could get access to them?

It seems a bit wasteful to have other people going through the same build process that someone else has already done.

[foxy123]

someone earlier in the thread mentioned having a repository...

[jdong]

I personally don't recommend starting a repository of prevu'ed packages. Instead, if a package properly prevu builds, submit it as a backport request.

The trouble with repositories, is you get far far more people who will install packages from it in a knee-jerk reaction. The Backports team tries hard to make sure its packages are safe enough for the general user to install. If a package is not fit as a Backports package, then it's not fit for the general user to use, and it's a better idea for users to build it themselves.


With the majority of PC's, building a package is not that intensive a process.

I get this error when trying to prevu libhal-dev, is there an easy solution for this? Thanks

Im on edgy amd64 using prevu 0.4.1-0ubuntu1

Edit:

Oh yeah, this is probably my problem:

Does this mean I need to prevu libvolume-id-dev first?

Edit2: I prevu'd libvolume-id-dev , it builds fine, but still ends with an error, any clues on this? :

Edit3: Couldnt get prevu to work so I built these in pbuilder, built just fine.

Is it safe to assume they work? I mean udev isnt something Id like to break.

[jdong]

It is not at all safe to assume that they work

udev versions need to match up with the kernel's udev counterpart's version in terms of compatibility... if not, you'll end up with an unbootable system and will be digging for your LiveCD's

Try at your own risk

Fascinating... I'll have to investigate that error.

[xopher]

Yeah, I thought it wouldn't be the best idea. Oh well - We found a solution with the developer of bmpx, so it will still work with libhal 0.5.7.1 - no need for the update. Thanks a lot anyway!
