HOWTO

# libsodium 1.0.20
# ================
# Slackware 15.0: libsodium 1.0.18

# Download

# Prerequisites:
# binutils

# Get the tarball
cd
test -f installed/libsodium-1.0.20.tar.gz &&
mv -f installed/libsodium-1.0.20.tar.gz .
test ! -f libsodium-1.0.20.tar.gz &&
wget https://download.libsodium.org/libsodium/releases/\
libsodium-1.0.20.tar.gz

# Verify tarball w/ sha256sum:
# (this came from my gpg-verified tarball)
echo "ebb65ef6ca439333c2bb41a0c1990587288da07f6c7fd07cb3a18cc18d30ce\

# Verify tarball w/ gpg:
( gpg --list-keys 2B6F76DA > /dev/null 2>&1 || gpg --recv-keys 2B6F76DA ) &&
wget -nc https://download.libsodium.org/libsodium/releases/\
libsodium-1.0.20.tar.gz.sig &&
  gpg --verify libsodium-1.0.20.tar.gz.sig && rm libsodium-1.0.20.tar.gz.sig

# Extract the source
mkdir -p -m 0700 ~/src

# To match the prefix that Slackware uses in it's package, use
# --prefix=/usr

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

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

# Build it
# If the build fails with assembler errors, try upgrading binutils
make

# Check the build
make check

# Become root to install it
su

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

# If you used --disable-static above, remove old static library

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