Other Btrfs options in the kernel are optional. BTRFS Programs Install btrfs-progs by running the following commands: sed -i '1,100 s/\.gz//g' Documentation/Makefile.in && ./configure --prefix=/usr \ --bindir=/bin \ --libdir=/lib && make Before running tests, build a support program and disable several that fail: make fssum && sed -i '/found/s/^/: #/' tests/convert-tests.sh && mv tests/misc-tests/025-zstd-compression/test.sh{,.broken} && mv tests/convert-tests/010-reiserfs-basic/test.sh{,.broken} && mv tests/convert-tests/011-reiserfs-delete-all-rollback/test.sh{,.broken} && mv tests/fuzz-tests/003-multi-check-unmounted/test.sh{,.broken} && mv tests/fuzz-tests/009-simple-zero-log/test.sh{,.broken} To test the results, issue (as the root user): pushd tests ./fsck-tests.sh ./mkfs-tests.sh ./cli-tests.sh ./convert-tests.sh ./misc-tests.sh ./fuzz-tests.sh popd Install the package as the root user: make install && ln -sfv ../../lib/$(readlink /lib/libbtrfs.so) /usr/lib/libbtrfs.so && rm -v /lib/libbtrfs.{a,so} && mv -v /bin/{mkfs,fsck}.btrfs /sbin sed ... Documentation/Makefile.in: Disables compressing man pages to be consistent with the rest of BLFS. --disable-documentation: This option is needed if the recommended dependencies are not installed. mv tests/{cli,convert,misc,fuzz}-tests/ ...: Disables tests that fail and prevent tests from completing. ln -s ... /usr/lib/libbtrfs.so: Creates a symbolic link in the directory where it is expected. rm /lib/libbtrfs.{a,so}: Removes unneeded library entries.
