6.21. Attr-2.4.47

The attr package contains utilities to administer the extended attributes on filesystem objects.

Approximate build time: less than 0.1 SBU
Required disk space: 3.4 MB

6.21.1. Installation of Attr

Modify the documentation directory so that it is a versioned directory:

sed -i -e 's|/@pkg_name@|&-@pkg_version@|' include/builddefs.in

Prevent installation of manual pages that were already installed by the man pages package:

sed -i -e "/SUBDIRS/s|man[25]||g" man/Makefile

Prepare Attr for compilation:

./configure --prefix=/usr \

Compile the package:


The tests need to be run on a filesystem that supports extended attributes such as the ext2, ext3, or ext4 filesystems. The tests are also known to fail if running multiple simultaneous tests (-j option greater than 1). To test the results, issue:

make -j1 tests root-tests

Install the package:

make install install-dev install-lib
chmod -v 755 /usr/lib/libattr.so

The shared library needs to be moved to /lib, and as a result the .so file in /usr/lib will need to be recreated:

mv -v /usr/lib/libattr.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libattr.so) /usr/lib/libattr.so
