HOWTO

# lzo 2.10 (2017-03-01)
# ========
# Slackware 14.0, 14.1: lzo 2.03
# Slackware 14.2: 2.09
# Slackware 15.0: 2.10

# I no longer include version 1.x here.  1.08, for example, was released
# way back in 2002.
#
# If you still have 1.x installed, you can safely install both at the same
# time.  The 1.x includes go into /usr/local/include and the library is
# named liblzo.*, the 2.x includes go into /usr/local/include/lzo and the
# library is named liblzo2.*

# Older versions of this HOWTO used prefix /usr/local, but we now use
# /usr to match the path of Slackware packages
#
# Remove an old version of lzo by running 'make uninstall' as root from
# a configured source directory

# If you want to uninstall lzo, or clean up files from an old version
# before installing a new one, skip down to the bottom for instructions

# Prerequisites (for both versions):
# gawk
# sed
# nasm
# zlib

# Get the tarball
cd

# At least read README and INSTALL
# If upgrading, also read NEWS

# If you do not want static library, use --enable-static=no

# Configure the build for 64-bit
test $(uname -m) = 'x86_64' &&
./configure --enable-shared --prefix=/usr --libdir=/usr/lib64

# Configure the build for anything else
test $(uname -m) = 'x86_64' &&
./configure --enable-shared --prefix=/usr

# Build it
make

# Check the build
make check

# Run a full test
make test

# Become root to install it
su

# Remove the Slackware package, if there is one
# [ You may want to keep a copy of the real (non-symlink) shared library
#   file just in case ]
test -x /sbin/removepkg && /sbin/removepkg lzo

# Install it
make install

# Become yourself again

# Save the source for later
