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 Generating documentation: - asciidoc - text document format tool - xmlto - text document format tool 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. See https://btrfs.wiki.kernel.org/index.php/Btrfs_source_repositories#Dependencies . 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 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: * autconf, 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.
