Hi Helmut, Thanks for the clarifications!

Actually debian/rules is a Makefile itself and it does set CC/CXX/etc to gcc/g++/etc by default or pass their values from env. The part that was unclear for me was that the proper build configuration is not yet known by debian/rules and is populated inside dh_auto_build - I always thought that all these variables are already known and somehow passed to debian/rules. Thus overriding CC/CXX/etc before dh_auto_build is called is quite pointless. > We have > two choices here: > * include some other makefile to set up these variables. > * Do not use them.

I was trying to keep Makefile patching at minimum, because for this project all Makefiles are generated by a custom tool and will most probably differ significantly in future versions. What sounds sane to me is to push a change upstream, that makes all the makefiles honour CC/CXX/etc, including CFLAGS/LDFLAGS instead of CCDEF/LDDEF. BTW what would be your recommendation - to upload again with a patch or to wait for the upstream release that includes the fixes (ETA is a week or two)? > > I'd appreciate if you give me a pointer on how to setup a cross > I suppose that you either use sbuild or pbuilder.
