If you want to make that argument, let's start another thread for it. We have added the LUA code in the proper place following existing precedent. > > in CMD components are the same references to LUA sources. > Where? I'm not seeing any more references to LUA_OBJS in Makefiles except for libzpool and the kernel. you try to use the same mistake with ZFS shared sources files - they should > be moved to shared place instead of use of files from UTS place: by build > procedure for cmd/zfs cmd/zpool, lib/libzfs* i can see it and it is really > hard to understand how is ZFS code shared. > The LUA code shouldn't be built into cmd/zfs, cmd/zpool/, or lib/libzfs*. If it is then we will fix that, but I don't see that it is. --matt > and you try to build the same source with different build flags: i know > it, because i did more gcc warnings cleanups. > much more better to use $(SRC)/common place where you can find shared > sources between components in different places. > > >> for private library add -sys and use it for cmd components. >> > > I don't understand what you're suggesting here.
