Contents: REQUIREMENTS INSTALLATION libdns examples drill INFORMATION FOR SPECIFIC OPERATING SYSTEMS Mac OS X Solaris KNOWN ISSUES pyldns Your Support Project page: http://www.nlnetlabs.nl/ldns/ On that page you can also subscribe to the ldns mailing list. * 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) - 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-<VERSION> 3. ./configure 4. gmake (it needs gnu make to compile, on systems where GNU make is the default you can just use 'make') 5. sudo gmake install 6. Optional. (cd examples; ./configure; gmake), make example programs included. 7. Optional. (cd drill; ./configure; gmake; gmake install), to build drill. You can configure and compile it in a separate build directory. * Examples There are some examples and dns related tools in the examples/ directory. These can be built with: 1. cd examples/ 2. ./configure [--with-ldns=<path to ldns installation or build>] 3. gmake * Drill Drill can be built with: 1. cd drill/ 2. ./configure [--with-ldns=<path to ldns installation or build>] 3. gmake Note that you need to set LD_LIBRARY_PATH if you want to run the binaries and you have not installed the library to a system directory. You can use the make target all-static for the examples to run them if you don't want to install the library. * Building from subversion 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.svn. Note that the actual commands may be a little bit different on your machine. Most notable, 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 o Matthijs Mekking Former main developers: o Jelte Jansen o Miek Gieben * Credits We have received patches from the following people, thanks! o Bedrich Kosata o Erik Rozendaal o Håkan Olsson o Jakob Schlyter o Paul Wouters o Simon Vallet o Ondřej Surý 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 (that 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: http://www.nlnetlabs.nl/projects/ldns/bugs * pyldns Compiling pyldns produces many ``unused parameter'' warnings. Those are harmless and may safely be ignored. Also when building with Swig which version is before 2.0.4, compiling pyldns produces many ``missing initializer'' warnings. Those are harmless too.

You can download them, not only from the NLnet Labs website but also through the various OS distributions for which NSD, ldns, and Unbound are packaged. We therefore have little idea who uses our software in production environments and have no direct ties with 'our customers'. 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. In addition to the moral support you can also support us financially.
