* 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

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.
