6.25. Acl-2.2.52

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: 4.8 MB

6.25.1. Installation of Acl

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

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

Fix some broken tests:

sed -i "s:| sed.*::g" test/{sbits-restore,cp,misc}.test

Fix a problem in the test procedures caused by changes in perl-5.26:

sed -i 's/{(/\\{(/' test/run

Additionally, fix a bug that causes getfacl -e to segfault on overly long group name:

sed -i -e "/TABS-1;/a if (x > (TABS-1)) x = (TABS-1);" \

Prepare Acl for compilation:

./configure --prefix=/usr    \
            --disable-static \

Compile the package:


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 -j1 tests after Coreutils has been built later in this chapter.

Install the package:

make install install-dev install-lib
chmod -v 755 /usr/lib/libacl.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/libacl.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libacl.so) /usr/lib/libacl.so
