[opensuse-packaging] Defining a macro if it is NOT yet defined

Hi, I am trying to define a macro unless this is already defined in the project configuration. I am doing this: %{!?go_arches: %define go_arches %ix86 x86_64 aarch64 ppc64le} But the build fails in openSUSE:Factory:Staging:adi:333 where go_arches is not defined. However, if I explicetly define it in the spec file, as in %define go_arches %ix86 x86_64 aarch64 ppc64le the builds success ... so my guess is that I am not really defining go_arches if go_arches is not defined. Does anyone knows how to correctly check that? What am I doing wrong? thanks in advance jordi -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org
