6.21. Acl-2.2.53

The Acl package contains utilities to administer Access Control Lists, which are used to define more fine-grained discretionary access rights for files and directories.

Approximate build time: less than 0.1 SBU
Required disk space: 6.4 MB

6.21.1. Installation of Acl

Prepare Acl for compilation:

./configure --prefix=/usr         \
            --bindir=/bin         \
            --disable-static      \
            --libexecdir=/usr/lib \
            --docdir=/usr/share/doc/acl-2.2.53

Compile the package:

make

The Acl tests need to be run on a filesystem that supports access controls after Coreutils has been built with the Acl libraries. If desired, return to this package and run make check after Coreutils has been built later in this chapter.

Install the package:

make install

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/libacl.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libacl.so) /usr/lib/libacl.so
