Most header files are the same for every flavour; those go in the common header package. Generated header files and symbol version information go in the per-flavour header packages, as does the top-level Makefile. The build system (Kbuild) is yet another package; this helps to support cross-building. > And even more why *.h files are empty at 686 dir?: > > root@dbc:/usr/src# ls > -l ./linux-headers-3.0.0-1-686-pae/include/config/*.h|head -5 > -rw-r--r-- 1 root root 0 Aug 27 > 19:24 ./linux-headers-3.0.0-1-686-pae/include/config/3c359.h > -rw-r--r-- 1 root root 0 Aug 27 > 19:24 ./linux-headers-3.0.0-1-686-pae/include/config/3c515.h > -rw-r--r-- 1 root root 0 Aug 27 > 19:24 ./linux-headers-3.0.0-1-686-pae/include/config/6pack.h > -rw-r--r-- 1 root root 0 Aug 27 > 19:24 ./linux-headers-3.0.0-1-686-pae/include/config/8139cp.h > -rw-r--r-- 1 root root 0 Aug 27 > 19:24 ./linux-headers-3.0.0-1-686-pae/include/config/8139too.h Those are generated by Kbuild; you'll find them in any kernel build tree. > How to use older Makefiles with strings like: > <...> > KDIR := /lib/modules/$(shell uname -r)/build > <...> > default: > $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules That command is still correct. > For example with very simple test self-made:) module I get: > > make -C /lib/modules/3.0.0-1-686-pae/build > SUBDIRS=/home/cc/code/c/module modules > make[1]: Entering directory `/usr/src/linux-headers-3.0.0-1-686-pae' > CC [M] /home/cc/code/c/module/tm.o > /home/cc/code/c/module/tm.c: In function 'init_module': > /home/cc/code/c/module/tm.c:21:12: warning: assignment from > incompatible pointer type > /home/cc/code/c/module/tm.c:22:17: error: 'NF_IP_PRE_ROUTING' > undeclared (first use in this function) [...] This has nothing to do with the separation between packages.
