Robert? IMO this makes at least more sense then what we have now and I just tested this now with and without a seperate build directory with experimental branch and it works TARGET_CPPFLAGS = @TARGET_CPPFLAGS@ -nostdinc -isystem $(shell $(CC) -print-file-name=include) -I$(srcdir)/include -I$(builddir) -I$(builddir)/include -Wall -W -- Felix Zielcke Proud Debian Maintainer and GNU GRUB developer _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
