The Btrfs utility programs require the following libraries/tools to build:
2007-06-12 15:39:09 +00:00
- libuuid - provided by util-linux, e2fsprogs/e2fslibs or libuuid
- libblkid - block device id library
- liblzo2 - LZO data compression library
- zlib - ZLIB data compression library
- libzstd - ZSTD data compression library version >= 1.0.0
2007-06-12 15:39:09 +00:00
For the btrfs-convert utility:
- e2fsprogs - ext2/ext3/ext4 file system libraries, or called e2fslibs
- libreiserfscore - reiserfs file system library version >= 3.6.27
Optionally, the checksums based on cryptographic hashes can be implemented by
external libraries. Builtin implementations are provided in case the library
dependencies are not desired.
- libgcrypt
- libsodium
- libkcapi
For zoned device support, the system headers installed in /usr/include/linux
must be 5.10 or newer.
Generating documentation:
2007-06-12 15:39:09 +00:00
- asciidoc - text document format tool

Update/clean up btrfs help and man page V2 Hi all, enclose you can find a patch which improves the help of the btrfs commands, updates the INSTALL file and the btrfs (command) man page. Regarding the help of the btrfs command: - moved the "subvolume set-default" command in the "subvolume" commands group - removed a wrong new line - small tweak on the basis of Andreas suggestion Regarding the btrfs command man page: - renaming the command "device balance" in "filesystem balance" (thanks to Andreas Phillipp to highlight that) - adding the entry "subvolume find-new" - document the switches of the command "filesystem defrag" - document the <devid> facility of the command "filesystem resize" - small tweak on the basis of Andreas suggestion Regarding the INSTALL file, which was very old, I removed the reference of the old btrfsctl utility and changed the examples using the btrfs command. I removed the old (and now wrong) statement about the inability to delete a subvolume/snapshot Chris, you can pull the patch from the branch "help_cleanup" of the following repository. http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git (or you can browse the changes at http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git/?p=btrfs- progs-unstable-all.git;a=summary) The patch is very simple: only updates the man page, the INSTALL file and moves/updates some lines in the help of btrfs command.

The build utilizes autotools, dependencies for generating the configure
scripts are:
* autoconf, autoheader
* automake, aclocal
* pkg-config
Statically built binaries
-------------------------
The makefiles are ready to let you build static binaries of the utilities. This
may be handy in rescue environments. Your system has to provide static version
of the libraries.
$ make static
$ make btrfs.static
$ make btrfs-convert.static
The resulting binaries have the '.static' suffix, the intermediate object
files do not conflict with the normal (dynamic) build.
All-in-one binary (busybox style)
---------------------------------
Since version 5.2 it's possible to build a single binary that can act as other
standalone tools, based on the file name:
$ make btrfs.box
$ mv btrfs.box btrfs
$ ln -s btrfs mkfs.btrfs
The list of built-ins can be obtained by
$ btrfs help --box
The basic set will always contain: mkfs.btrfs, btrfs-image, btrfs-convert.
32bit build on 64bit host
-------------------------
The combination of 32bit build on 64bit host could work but depends on the
libraries that must provide the 32bit versions, or even 32bit static versions.
This is fairly uncommon on contemporary distributions and building 32bit
versions on a 32bit host is recommended.
