Subject: [XEN PATCH v3 19/25] tools: Introduce $(xenlibs-ldlibs, ) macro
Date: Fri, 24 Jun 2022 17:04:16 +0100 [thread overview]
Message-ID: <20220624160422.53457-20-anthony.perard@citrix.com> (raw)
In-Reply-To: <20220624160422.53457-1-anthony.perard@citrix.com>
This can be used when linking against multiple in-tree Xen libraries,
and avoid duplicated flags. It can be used instead of multiple
$(LDLIBS_libxen*).
For now, replace the open-coding in libs.mk.
The macro $(xenlibs-libs, ) will be useful later when only the path to
the libraries is wanted (e.g. for checking for dependencies).
