From ed550a49d2114c56e5bc033ecd0e83073d2d4067 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 10 Aug 2018 10:10:15 +0000 Subject: libtool-cross: Handle ccache sstate 'infection' issues On a system without ccache, f you: INHERIT += "ccache" bitbake libtool-cross bitbake apmd then it fails due to being unable to find ccache. The references to ccache are coded into libtool-cross but the sstate checksum doesn't reflect this due to the way the class is coded (output should be the same regardless). The simplest solution is to remove references to ccache from the libtool script. The output then works regardless of whether ccache is present or not. The libtool-cross script is only used in a handful of cases (most of the time its dynamically generated by autoconf) so any performance issue is minor.
