I guess you could do something like (for C and C++ respectively for sane upstreams, you might not need the CXX part given what you wrote): # do the dpkg-buildflags dance to get everything exported CFLAGS += $(CPPFLAGS) CXXFLAGS += $(CPPFLAGS) so that the CPPFLAGS aren't lost? Of course, you could avoid exporting everything to retain control over what's exported to the rest of the build process, in which case you could do something along those lines: CPPFLAGS = $(shell dpkg-buildflags --get CPPFLAGS) CFLAGS = $(shell dpkg-buildflags --get CFLAGS ) $(CPPFLAGS) CXXFLAGS = $(shell dpkg-buildflags --get CXXFLAGS) $(CPPFLAGS) LDFLAGS = $(shell dpkg-buildflags --get LDFLAGS ) then pass those variables explicitly to ./configure: dh_auto_configure -- ... CFLAGS="$(CFLAGS)" CXXFLAGS="$(CXXFLAGS)" LDFLAGS="$(LDFLAGS)" There are probably other ways to do this in compat 9, but I didn't investigate it yet. Mraw, KiBi.
