2.8. Software Collection Macros


The Software Collection packaging macro scl defines where to relocate the Software Collection's file structure. The relocated file structure is a file system used exclusively by the Software Collection.
The %scl_package macro defines files ownership for the Software Collection's metapackage and provides additional packaging macros to use in the Software Collection environment.
To be able to build a conventional package and a Software Collection package with a single spec file, prefix the Software Collection macros with %{?scl:macro}, as in the following example:
%{?scl:Requires:%scl_runtime}
In the example above, the %scl_runtime macro is the value of the Requires tag. Both the macro and the tag use the %{?scl: prefix.
