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. CXXFLAGS set in debian/rules were not used at all, this is also fixed. --- debian/rules.old 2016-11-21 21:00:13.000000000 +0000 +++ debian/rules 2016-11-21 21:02:13.000000000 +0000 @@ -15,6 +15,8 @@ CXXFLAGS += -O2 endif +CXXFLAGS += -std=gnu++98 + # shared library versions, version=`ls src/.libs/lib*.so.* | \ awk '{if (match($$0,/[0-9]+\.[0-9]+\.[0-9]+$$/)) print substr($$0,RSTART)}'` @@ -33,7 +35,7 @@ configure-stamp: config-stamp dh_testdir - CFLAGS="$(CFLAGS) -Wl,-z,defs" \ + CXXFLAGS="$(CXXFLAGS)" CFLAGS="$(CFLAGS) -Wl,-z,defs" \ ./configure --host=$(DEB_HOST_GNU_TYPE) \ --build=$(DEB_BUILD_GNU_TYPE) --prefix=/usr \ --mandir=\$${prefix}/share/man --infodir=\$${prefix}/share/info cu Adrian -- "Is there not promise of rain?"
