Overview

RPM Package type.

Build RPMs without having to waste hours reading Maximum-RPM. Well, in case you want to read it, here: www.rpm.org/max-rpm/

The following attributes are supported:

• :rpm_rpmbuild_define - an array of definitions to give to rpmbuild. These are used, verbatim, each as: –define ITEM

Instance Method Details

#architecture ⇒ Object

Handle any architecture naming conversions. For example, debian calls amd64 what redhat calls x86_64, this method fixes those types of things.

    when "native"
      return %x{uname -m}.chomp   # 'native' is current arch
    when "all"
