Required disk space: 3.5 MB

6.22.1. 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 Man-Pages package:

sed -i -e "/SUBDIRS/s|man2||" man/Makefile

Prepare Attr for compilation:

./configure --prefix=/usr

Compile the package:


The Attr tests need to be run on a filesystem that supports extended attributes. To test the results, issue:

make -k 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/libattr.so.1 /usr/lib/libattr.so
