Control: tags -1 patch What broke the build is that gcc 6 changed the default C++ standard from C++98 to C++14.
Not all valid C++98 code is also valid C++11 and C++14 code. Note that this just changed the default, when told to process C++98 code gcc 6 does not differ in any significant way from gcc 5. Making the code compatible with C++14 would be the best possible solution, but as a workaround it is possible to fix the build with this change to tell gcc that this is C++98 code. --- debian/rules.old 2016-11-21 17:59:48.000000000 +0000 +++ debian/rules 2016-11-21 18:00:07.000000000 +0000 @@ -12,7 +12,7 @@ autoheader automake --add-missing autoconf - dh_auto_configure -- --datadir=/usr/share/doc + dh_auto_configure -- --datadir=/usr/share/doc CXXFLAGS="-O2 -Wall -std=gnu++98" .PHONY: override_dh_installdocs override_dh_installdocs: cu Adrian -- "Is there not promise of rain?"
