The e2fsprogs package contains the utilities for handling the ext2 file system. It also supports the ext3 and ext4 journaling file systems.
Approximate build time: 4.4 SBU on a spinning disk, 1.2 SBU on an SSD
Required disk space: 94 MB
8.74.1. Installation of E2fsprogs
The e2fsprogs documentation recommends that the package be built in a subdirectory of the source tree:
mkdir -v buildcd build
Prepare e2fsprogs for compilation:
../configure --prefix=/usr \ --sysconfdir=/etc \ --enable-elf-shlibs \ --disable-libblkid \ --disable-libuuid \ --disable-uuidd \ --disable-fsck
The meaning of the configure options:
-
--enable-elf-shlibs -
This creates the shared libraries which some programs in this package use.
-
--disable-* -
This prevents e2fsprogs from building and installing the
libuuidandlibblkidlibraries, theuuidddaemon, and the fsck wrapper, as util-linux installs more recent versions.
Compile the package:
make
To run the tests, issue:
make check
One test, u_direct_io, is known to fail on some systems.
Install the package:
make install
Remove useless static libraries:
rm -fv /usr/lib/{libcom_err,libe2p,libext2fs,libss}.a This package installs a gzipped .info file but doesn't update the system-wide dir file. Unzip this file and then update the system dir file using the following commands:
gunzip -v /usr/share/info/libext2fs.info.gzinstall-info --dir-file=/usr/share/info/dir /usr/share/info/libext2fs.info
If desired, create and install some additional documentation by issuing the following commands:
makeinfo -o doc/com_err.info ../lib/et/com_err.texinfoinstall -v -m644 doc/com_err.info /usr/share/infoinstall-info --dir-file=/usr/share/info/dir /usr/share/info/com_err.info
