HOWTO

# LDNS 1.8.3
# ==========
# Prerequisites:
# libpcap (optional; needed for examples/ldns-dpa)
# libtool
# doxygen
# OpenSSL (if you want crypto features)
# Python (optional; if you want Python bindings --with-pyldns)
# GOST engine for OpenSSL (leave off --disable-gost)

# 1.8.3 release announcement
# 1.7.x does support OpenSSL >= 1.1.0
# 1.8.x did build for me with OpenSSL 3.0.11

# Get it
cd

# Build it

# Install it

# You may find that you have old shared library files,
# if you're upgrading, in /usr/local/lib*/
# If you're 100% sure (try lsof, etc.) that nothing is using it,
# such as the sshd that you're using to connect to the server
# remotely, zap it and run ldconfig again
# Anything using the old shared library file should be rebuilt,
# but could possibly be fine just restarting it if the new
# version is binary compatible with the older one

# Make sure your non-root user can remove the source later
chown -R $(logname) .
chmod -R u+w .

# Become your non-root user again

# Keep the source for later
