error: Macro % has illegal name (%define)

Question

I have a build support script for building my packages. Now I want to automatically set the Version in my spec files. I use the macro %{auto_version} for that. In my script I want to invoke rpmbuild -D 'auto_version 1.1' packet.spec for example.

#!/bin/bash
version=$(version.sh)
#snip
define="'auto_version ${version}'"

build_spec () {
    spec=$1
    define=$2
    #snip
    build_output=$(rpmbuild -D "$define" $spec)
    # snip
}

build_spec $build_spec "$define"

However this generates the error error: Macro % has illegal name (%define)

I've tried different escaping, quoting and making define an array, handled with ${define[@]}.

Answer 1

As @tripleee right points, the reason of error: Macro % has illegal name (%define) is extra quotes in -D|--define directives like:

-D "\"_gpg_name $gpgname\""

the right version is:

-D "_gpg_name $gpgname"
