From 2e1b15a6fba60f077fad070738801b592c794038 Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Mon, 13 Feb 2017 18:24:51 +0100 Subject: [PATCH] domoticz: fix build on powerpc64le There is an issue with powerpc64le and boost::uuids::random_generator on the following line of code (from include/boost/uuid/seed_rng.hpp): sha.process_bytes( (unsigned char const*)&std::rand, sizeof( void(*)() ) ) This line "inspects the first couple bytes (here eight) of the std::rand function to seed some rng. Due to the implementation of process_bytes and inlining happening, it seems that one of the loops therein uses &rand-1 as some boundary, compiling with -O0 makes that reloc come out as 'rand + 0' and the link will succeed."
