The configure phase can detect the following: - no /usr/include/blkzoned.h - no zoned support possible - usable /usr/include/blkzoned.h - on by default - present /usr/include/blkzoned.h but unusable due to missing struct members or ioctl defintion Case 3 could be confusing, so document the requirements.

Installation instructions
|
|
=========================
|
|
|
|
The Btrfs utility programs require the following libraries/tools to build:
|
|
|
|
- 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
|
|
|
|
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:
|
|
|
|
- asciidoc - text document format tool
|
|
- xmlto - text document format tool
|
|
- source-highlight - optional, only for generating HTML output
|
|
|
|
XATTR library should be provided by the standard C library or by
|
|
|
|
- libattr - extended attribute library
|
|
|
|
Please note that the package names may differ according to the distribution.
|
|

Building from sources
|
|
---------------------
|
|
|
|
To build from git sources you need to generate the configure script using the
|
|
autotools:
|
|
|
|
$ ./autogen.sh
|
|
|
|
To build from the released tarballs:
|
|
|
|
$ ./configure
|
|
$ make
|
|
$ make install
|
|
|
|
To install the libbtrfsutil Python bindings:
|
|
|
|
$ make install_python
|
|
|
|
You may disable building some parts like documentation, btrfs-convert or
|
|
backtrace support. See ./configure --help for more.
|
|
|
|
Specific CFLAGS or LDFLAGS should be set like
|
|
|
|
$ CFLAGS=... LDFLAGS=... ./configure --prefix=/usr
|
|
|
|
and not as arguments to make. You can specify additional flags to build via
|
|
variables EXTRA_CFLAGS and EXTRA_LDFLAGS that get appended to the predefined
|
|
values of the respective variables. There are further build tuning options
|
|
documented in the Makefile.
|
|
|
|
$ make EXTRA_CFLAGS=-ggdb3
|
|
|
|
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.
