External Dependencies
=====================
External dependencies are linked outside the getdns API build tree (we rely on configure to find them). We would like to keep the dependency tree short.
The project relies on [libldns from NL](https://www.nlnetlabs.nl/projects/ldns/) for parsing and constructing DNS packets. Version 1.6.16 (note that building ldns may require openssl headers and libraries)
The project also relies on [libunbound from NL](http://www.nlnetlabs.nl/projects/unbound/). Currently it relies on svn revision 2985. The unbound.2985.patch must be applied to the source tree as well. The ./configure must be run with the --with-libevent option (recommended to also use --with-libunbound-only)
Although [libevent](http://libevent.org) is used initially to implement the asynchronous model, future work may include a move to other mechanisms (epoll based etc.). Version 2.0.21 stable
Doxygen is used to generate documentation, while this is not technically necessary for the build it makes things a lot more pleasant.
GNU autoconf is used to generate the configure script (and consequently the Makefiles)
Automake 1.12 is required if you are building the distribution tarball.
* [libevent](http://libevent.org) version 2.0.21 stable
* [libldns from NL](https://www.nlnetlabs.nl/projects/ldns/) version 1.6.16 (ldns may require openssl headers and libraries)
* [libunbound from NL](http://www.nlnetlabs.nl/projects/unbound/) svn revision 2985, configure must be run with the --with-libevent option (recommended to also use --with-libunbound-only). The unbound.2985.patch included with getdns must be applied to the source tree prior to building libunbound.
* Doxygen is used to generate documentation, while this is not technically necessary for the build it makes things a lot more pleasant.
Assuming that the getdns sources are in a diretory named getdns in your home directory, to build libunbound (note that the svn checkout may take a while):
```
# mkdir unbound
# cd unbound
# svn checkout -r 2985 http://unbound.nlnetlabs.nl/svn
# cd svn/trunk
# patch -p0 < ~/getdns/unbound.2985.patch
# ./configure --with-libevent --with-libunbound-only
# make
# make install
```
#Supported Platforms
