• Development ldns is mainly developed on Linux and FreeBSD. It is regularly tested to compile on other systems like Solaris and Mac OS X.

REQUIREMENTS

• OpenSSL (Optional, but needed for features like DNSSEC)
  • OpenSSL >= 0.9.7f for DANE support
  • OpenSSL >= 1.0.0 for ECDSA and GOST support
• libpcap (Optional, but needed for examples/ldns-dpa)
• (GNU) libtool (in OSX, that’s glibtool, not libtool)
• GNU make

INSTALLATION

1. Unpack the tarball
2. cd ldns-
3. ./configure –with-examples –with-drill (optionally compile python bindings too with: –with-pyldns)
4. make
5. make install

• Building from repository

If you are building from the repository you will need to have (gnu) autotools like libtool and autoreconf installed. A list of all the commands needed to build everything can be found in README.git. Note that the actual commands may be a little bit different on your machine. Most notably, you’ll need to run libtoolize (or glibtoolize). If you skip this step, you’ll get an error about missing config.sub.

• Developers ldns is developed by the ldns team at NLnet Labs. This team currently consists of: o Willem Toorop o Wouter Wijngaards

Former main developers: o Jelte Jansen o Miek Gieben o Matthijs Mekking

INFORMATION FOR SPECIFIC OPERATING SYSTEMS

MAC OS X

For MACOSX 10.4 and later, it seems that you have to set the MACOSX_DEPLOYMENT_TARGET environment variable to 10.4 before running make. Apparently it defaults to 10.1.

This appears to be a known problem in 10.2 to 10.4, see: http://developer.apple.com/qa/qa2001/qa1233.html for more information.

SOLARIS

In Solaris multi-architecture systems (which have both 32-bit and 64-bit support), it can be a bit taxing to convince the system to compile in 64-bit mode. Jakob Schlyter has kindly contributed a build script that sets the right build and link options. You can find it in contrib/build-solaris.sh

KNOWN ISSUES

A complete list of currently known open issues can be found here: https://github.com/NLnetLabs/ldns/issues

• pyldns Compiling pyldns produces many unused parameter'' warnings. Those are harmless and may safely be ignored. Also, when building with SWIG older than 2.0.4, compiling pyldns produces many missing initializer’’ warnings. Those are harmless too.

Therefore, we ask you to contact us at users@NLnetLabs.nl and tell us whether you use one of our products in your production environment, what that environment looks like, and maybe even share some praise. We would like to refer to the fact that your organization is using our products. We will only do that if you explicitly allow us. In all other cases we will keep the information you share with us to ourselves.
