Thanks, I haven't tried this yet, but it looks promising! For the record, right now I use a GNUmakefile (which takes precedence over the Makefile) in the build directory containing e.g. MAKEARGS = ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- MAKEFLAGS += --no-print-directory .PHONY: all $(MAKECMDGOALS) all := $(filter-out all Makefile,$(MAKECMDGOALS)) all: $(MAKE) $(MAKEARGS) $(all) -f Makefile Makefile:; $(all) %/: all @: Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
