I have dunno.spec file with the following structure:

Name:                   dunno
Version:                 1.0
...
BuildArch:              x86_64

%description
...
%package common
Summary:                Shared files
BuildArch:              noarch

I suppose that after I run rpmbuild -ba dunno.spec I should get two binary packages:

  • dunno-1.0.x86_64.rpm
  • dunno-common-1.0.noarch.rpm

however I get:

  • dunno-1.0.x86_64.rpm
  • dunno-common-1.0.x86_64.rpm

If I remove the line BuildArch: x86_64 from the spec, then I get

  • dunno-1.0.noarch.rpm
  • dunno-common-1.0.noarch.rpm

How to fix that?

RPM v4.4.2.3.

  • Good question. If that didn't work I'm not sure you can do it. Though it looks like it is possible in newer versions of RPM than what CentOS 5 has. – Etan Reisner Jan 09 '15 at 14:43
  • @EtanReisner: Could you please share the link to e.g. "what's new" which describes in what RPM version that feature has been implemented? – dma_k Jan 09 '15 at 18:37

    I don't know. I mentioned that only because the CentOS 6 glib2.spec has a `noarch` `-doc` package in it. [This](http://pkgs.fedoraproject.org/cgit/glib2.git/tree/glib2.spec?h=f18) seems to be the first tagged version of the Fedora specfile that has that. So somewhere between the CentOS 5 4.4.2.3 and whatever F18 has. Which looks like [4.10.3.1](http://pkgs.fedoraproject.org/cgit/rpm.git/tree/rpm.spec?h=f18). But that's a huge range and it might have been anywhere in there. – Etan Reisner Jan 09 '15 at 18:46
  • Yes, indeed `glib2` package has several flavours in [repo](https://dl.fedoraproject.org/pub/fedora/linux/releases/21/Everything/x86_64/os/Packages/g/). Hopefully this feature was not introduced by a patch (there are more then 10, but all seem to be unrelated). It seems that the only solution for v4.4 is to run `rmpbuild` twice. – dma_k Jan 09 '15 at 19:14

Split the build into 2 packages, one x86_64, the other noarch.

You can do 2 builds from a single spec using %ifarch logic (but its usually easier/cleaner to use 2 spec files even if annoying).

It also hurts nothing to include platform-independent content in an x86_64 sub-package instead of a noarch sub-package.

  • In case of splitting I would need to maintain other common fields like `Version`, `Url`, `License`. Also the difficulty is that common staff is installed during the build cycle, so two specs will cause two full build cycles (not good). I can of course trick the build so that "light" build cycle is run, but would be conceptually right? Inclusion does not hurt, but I have hidden part of the story: spec produces 3 platform-dependent binary packages, all of them depending on shared platform-independent staff (e.g. settings). – dma_k Jan 09 '15 at 18:47
  • And how `%ifarch` can help? For example, if I add `%ifarch noarch` then again I would need to run `rpmbuild` twice (`rpmbuild --target=x86_64` and `rpmbuild --target=noarch`). – dma_k Jan 09 '15 at 18:50

    I'd just use all x86_64 sub-packages instead of attempting a noarch sub-package. Lots of x86_64 packages have only noarch content. – Jeff Johnson Jan 09 '15 at 18:51
  • Yes %ifarch would need to be built twice, once for x86_64, once for noarch. But Version: etc would be identical and simple to maintain. – Jeff Johnson Jan 09 '15 at 18:53
  • Thanks for comments. I think it would be reasonable for me to give up and have `.x86_64` for all packages. – dma_k Jan 09 '15 at 19:06

You could run the rpmbuild as this rpmbuild --target=x86_64,noarch ... then rpmbuild will build the package two pass for each arch.

you should make dunno-common a subpackage

your spec should look like this

Name:                   dunno
Version:                 1.0
# next line is not needed
BuildArch:              x86_64

%package common
BuildArch:              noarch
Summary: ...
%description common
%files 
# ...
