Add build system Add autoconf style build infrastructure to the ZFS tree. This includes autogen.sh, configure.ac, m4 macros, some scripts/*, and makefiles for all the core ZFS components.

It also allows the libzfs developers to modify the list of required libraries and cflags without breaking existing applications. The following example illustrates how pkg-config can be used: cc `pkg-config --cflags --libs libzfs` -o myapp myapp.c /* * myapp.c */ void main() { libzfs_handle_t *hdl; hdl = libzfs_init(); if (hdl) libzfs_fini(hdl); } Signed-off-by: Turbo Fredriksson <turbo@bayour.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes: #585

libzfs_pcdir = $(datarootdir)/pkgconfig
Support parallel build trees (VPATH builds) Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

Support custom build directories and move includes One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.

Add proper library versioning The zfs libraries were never properly versioned. Since the API has remained static for quite some time this we never an issue. However, going forward they should be versioned. This commit versions all of the libraries to 1.0.0. From here on out this version must be updated to reflect changes to the library.

Combine libraries: spl, avl, efi, share, unicode. These libraries, which are an artifact of the ZoL development process, conflict with packages that are already in distribution: * libspl: SPL Programming Language * libavl: AVL for Linux * libefi: GRUB And these libraries are potential conflicts: * libshare: the Linux Mount Manager * libunicode: Perl and Python Recompose these five ZoL components into the four libraries that are conventionally provided by Solaris and FreeBSD systems: + libnvpair + libuutil + libzpool + libzfs This change resolves the name conflict, makes ZoL more compatible with existing software that uses autotools to detect ZFS, and allows pkg-zfs to better reflect the official Debian kFreeBSD packaging.

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes. Add a missing call to fnvlist_free(nvl) in log_internal() that was added in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time (zfsonlinux/zfs@9e11c73) because it depended on future work.

Cleanup linking I noticed during code review of zfsonlinux/zfs#4385 that the author of a commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)` when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon further examination, it seems that he had copied what we do with `$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately, what we do is wrong, so lets fix it to set a good example for future contributors. In addition, we have multiple `-lz` and `-luuid` passed to the compiler because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is consistent with the recommendation to use `AC_SEARCH_LIBS` over `AC_CHECK_LIB` by autotools upstream: https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html In an ideal world, this would translate into improvements in ELF's `DT_NEEDED` entries, but that is not the case because of a couple of bugs in libtool. The first bug causes libtool to overlink by using static link dependencies for dynamic linking: https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues The workaround for this should be to pass `-Wl,--as-needed` in `LDFLAGS`. That leads us to the second bug, where libtool passes `LDFLAGS` after the libraries are specified and `ld` will only honor `--as-needed` on libraries specified before it: https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/ There are a few possible workarounds for the second bug. One is to either patch the compiler spec file to specify `-Wl,--as-needed` or pass `-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is specified early. Another is to patch ltmain.sh like Gentoo does: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed Without one of those workarounds, this cleanup provides no benefit in terms of `DT_NEEDED` entry generation. It should still be an improvement because it nicely simplifies the code while encouraging good habits when patching autotools scripts.

Fix libzfs_core changes to follow GNU libtool guidelines The GNU libtool documentation states to start with a version of 0:0:0, rather than 1:1:0. Illumos uses the name libzfs_core.so.1, so to be consistent, we should go with 1:0:0. http://www.gnu.org/software/libtool/manual/libtool.html#Updating-version-info The GNU libtool documentation also provides guidence on how the version information should be incremented. Doing this does a SONAME bump of the libzfs and libzpool libraries. This is particularly important on Gentoo because a SONAME bump enables portage to retain the older libraries until any packages that link to them are rebuilt. The main example of this is GRUB2's grub2-mkconfig, which will break unless it is rebuilt against the new libraries.
