From: Jeremy Rosen Date: Mon, 22 Sep 2014 11:31:08 +0000 (+0200) Subject: swig: add swig2.0 -> swig symlink X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03ecca90d38448491f106c6555905de0d904fab0;p=buildroot.git swig: add swig2.0 -> swig symlink The cmake detection script provided with cmake will first look for a binary called swig2.0 then for a binary called swig. host-swig only installs a binary called swig, but if the host distribution has instaled a binary called swig2.0, it will be preferred over our swig, which isn't great. This patch creates a symlink swig2.0 -> swig to prevent this from happening.
