2.12. Building a Software Collection

If you have correctly converted a conventional spec file for your Software Collection as documented in Section 2.10, “Converting a Conventional Spec File”, you will be able to build the resulting package in both the Software Collection and conventional build roots. Building the converted package in a conventional build root will produce a conventional base system RPM package, while building in a Software Collection build root that contains %{scl}-build will produce a Software Collection package.

To build a Software Collection on your system, run the following command:

 rpmbuild -ba package.spec --define 'scl name' 

The difference between the command shown above and the standard command to build conventional packages (rpmbuild -ba package.spec) is that you have to append the --define option to the rpmbuild command when building a Software Collection.

The --define option defines the scl macro, which uses the Software Collection configured in the Software Collection spec file (package.spec).

Alternatively, to be able to use the standard command rpmbuild -ba package.spec to build the Software Collection, specify the following in the package.spec file:

BuildRequires: software_collection-build

where software_collection is the name of the Software Collection.
