HOWTO

# Nettle 3.9.1
# ============
# Slackware 14.0: nettle 2.5
# Slackware 14.1: nettle 2.7.1
# Slackware 14.2: nettle 3.2
# Slackware 15.0: nettle 3.7.3

# Some things that (can) use Nettle are:
# GnuTLS
# lsh
# wget
# Wslay

# Prerequisites:
# GMP
# OpenSSL (optional; for OpenSSL compatibility)
# valgrind (optional)
# m4
# info (optional; for documentation)

# If you have trouble with the download URL below, try here instead:
# https://ftp.gnu.org/gnu/nettle/

# 3.9.1 release announcement

# Nettle 3.9.1 is source and binary compatible with Nettle 3.6

# Read README, INSTALL, and NEWS (if upgrading)

# If you want it to find OpenSSL when yours is under the /usr/local/ssl
# prefix, which is the default in < OpenSSL 1.1.0, put these at the
# beginning of your configure line (if 64-bit, use lib64 instead):
# LDCONFIG=-L/usr/local/ssl/lib CPPFLAGS=-I/usr/local/ssl/include

# Configure the build for 64-bit
test $(uname -m) = 'x86_64' &&
./configure --prefix=/usr --docdir=/usr/doc --infodir=/usr/info \
--libdir=/usr/lib64 --mandir=/usr/man

# Configure the build for anything else
test $(uname -m) != 'x86_64' &&
./configure --prefix=/usr --docdir=/usr/doc --infodir=/usr/info \
--mandir=/usr/man

# Build it
make

# Check the build
make check

# Become root to install it

# Remove the Slackware package, if there is one
test -x /sbin/removepkg && /sbin/removepkg nettle

# Install it

# If you installed it over an older version, check here for leftover
# files that are no longer necessary - generally if the date is not
# today, it's no longer used.
