You need to use separate projects/repositories

Only FYI: By chance I had also done it in a separated project, see https://bugzilla.suse.com/show_bug.cgi?id=856794#c35 Nevertheless it would be nice if it was possible in the same project - otherwise artificial separated projects are needed only to deal with technical constraints (assume the packages "foo" and "bar" fit semantically perfectly into one same project).

(just fyi) libgphoto2 is still used for in graphics for Tumbleweed, Factory and Leap which should be compatible in regards to the libgphoto2_port.so requirement.

According to https://build.opensuse.org/package/repositories/graphics/libgphoto2 you disabled the "Build Flag" for libgphoto2 for released openSUSE versions. Is this really what you intend? To avoid only this particular sane-backends dependency issue it should be sufficient to diable the "Use for Build Flag" for libgphoto2 for released openSUSE versions.

Hello,

in short:

I have a package "foo" in a development project where also a package "bar" in that same project exists that is used to build "foo".

I like to specify in my package "foo" not to use "bar" from that development project but to use "bar" from the repository that is used to build "foo".

Can I specify that in my package "foo" and if yes how can I do it?

You can disable the <useforbuild> flag. That way the build result is not copied to the full repository which is used for building further packages in your repo.

But that doesn't work on package granularity (to disable useforbuild only for building package foo). Richard.

But be warned, many people how are using this gets confused at some point of time.

In most cases it is cleaner to build your package in a differnt project.

...

Details:

I have "sane-backends" in its development project "graphics" where also "libgphoto2" exists.

sane-backends needs libgphoto2 to build.

I build sane-backends also for released openSUSE versions.

Now when a user of a released openSUSE version likes to install sane-backends from the graphics project he also needs libgphoto2 from the graphics project.

But unfortunately the newest version of libgphoto2 from the graphics project cannot be installed into released openSUSE versions without dependency issues because other packages in the released openSUSE versions need an older version of libgphoto2.

If I could build sane-backends in the graphics project not with libgphoto2 from the graphics project but with libgphoto2 from the repository that is used to build sane-backends, then sane-backends would require the libgphoto2 version of the released openSUSE versions and users could install sane-backends from the graphics project into their released openSUSE versions without dependency issues.

As a workaround the maintainer of libgphoto2 has now disabled in the graphics project that libgphoto2 is used for build for released openSUSE versions but this has the drawback that libgphoto2 is no longer used for build for all packages in the graphics project.

What I would prefer is that I could specify only in sane-backends how exactly I like to have this particular package built.

I know that I can disable the <useforbuild> flag for "bar" in a project (I use it in the "Printing" project).

But - as far as I understand it - the drawback is that then "bar" is also no longer used for building any other packages (like "baz") in the project.

Therefore I would prefer when I could specify only in my particular package "foo" not to use "bar" from the project.

If this is possible, what must I do?

I don't have a perfect solution, but a workaround: BuildRequires: bar < $version_in_devel_project I didn't test this, but I expect that this forces the use of the "old" package instead of the package in the devel project.
