It looks like, there is not so much that needs to be fixed for building criu from a top directory. After the patch it's possible to do `make criu/mount.o` i.e. It will build protobuf, compel as dependencies (if they are not built), but no more from criu objects. If something breaks, you can do make from vim and jump to error. Nice. Mostly the patch corrects pathes to objects - I tried to make them depend on $(obj) or $(SRC_DIR)/criu, where it's possible. After it tested: `make -j 10`, `make criu/log.o`, `make clean`, `make mrproper`, `make install DESTDIR=/tmp/criu`, `make uninstall DESTDIR=/tmp/criu` Note: I improperly called v1 for this patch as "return to make from top Makefile" -- but I didn't mean that (and it was friday ;) This patch doesn't yet switch to top-Makefile building, but that's a step in that way (building from a top Makefile needs correct pathes in makefiles) which also adds ability to build objects in subdirectories and etc. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Dmitry Safonov <dsafonov@virtuozzo.com> Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
