HOWTO

# liburcu 0.15.2
# ==============
# As I write this, Slackware-current has a liburcu package, but 15.0 and down
# do not

# If you ever want to uninstall liburcu, skip down to the bottom

# Get the tarball
cd
test -f installed/userspace-rcu-0.15.2.tar.bz2 &&
mv -f installed/userspace-rcu-0.15.2.tar.bz2 .
test ! -f userspace-rcu-0.15.2.tar.bz2 &&
wget https://lttng.org/files/urcu/userspace-rcu-0.15.2.tar.bz2

# Verify tarball w/ sha256sum:
echo "59f36f2b8bda1b7620a7eced2634f26c549444818a8313025a3bb09c0766a6\
1d  userspace-rcu-0.15.2.tar.bz2" | sha256sum -c

# Verify tarball w/ gpg:
( gpg --list-keys 17280A9781186ACF ||
  gpg --recv-keys 17280A9781186ACF ) &&
wget -nc https://lttng.org/files/urcu/userspace-rcu-0.15.2.tar.bz2.asc &&
  gpg --verify userspace-rcu-0.15.2.tar.bz2.asc &&
   rm userspace-rcu-0.15.2.tar.bz2.asc

# Extract the source

# Build it

make check

# Become root to install it

# Remove the Slackware package, if there is one

# If you ever want to uninstall liburcu, this should do it:
