PPA Build -- unmet dependencies. But builds on home box

Asked by Steve Butler

Attempting to build a PPA for Gnucash latest release v3.5. I am able to build on my local 19.04 box but sending code to Launchpad results in:

I took the debian files for Gnucash 3.4 posted on the debian site and modified them to build v 3.5 on my box. Uploaded same to my new PPA and the build fails as above. How to proceed?

If you are talking about then failed builds in https://launchpad.net/~kg7je/+archive/ubuntu/gnc-released-ppa

You tried building the packages for Ubuntu trusty, but several dependencies (at least debhelper (>= 11~), googletest, locales-all) do not exist in the standard repositories or trusty.

If you really want to build these packages for trusty, then you first have to find a solution for these dependent packages in trusty (either in an existing PPA, or by backporting theses packages to trusty in your own PPA). Otherwise it is not possible to build that gnucash package for trusty.

Thanks Manfred Hampl, that solved my question.

OK. I will research which direction I want to go.

As a general rule I'd normally advise at least attempting to relax the debhelper build-dependency to the version in trusty first; this may entail working out when it was introduced into the packaging you're using and what other changes would need to be reverted in order to work with an earlier version. It's usually (though not always) simpler than trying to backport debhelper.

Thanks Colin. I suspect I can downgrade to >= 9 and be fine. I don't see a version requirement on the GnuCash web site and was following the lead of the debian maintainer for the gnucash package for v 3.4.

I need to research how to get the other four packages loaded into my PPA so they will be available to build GnuCash. I am a total novice at this.

For googletest, all the build needs is access to the source. If I read debian/rules correctly, it simply copies from the main /usr area. So I also need to figure out how to package that into the GnuCash source and send to the PPA (with modified instructions in rules).

That leaves three dependencies to research further (libgwengui-gtk3-dev, libwebkit2gtk-4.0-dev and locales-all).

It is not possible to relate any results of the local build in disco to trusty. I suggest that you set up a local system with trusty (e.g. as a virtualized system or a build chroot) to experiment with the dependencies.
