Introduction to ldns

ldns is a fast DNS library with the goal to simplify DNS programming and to allow developers to easily create software conforming to current RFCs and Internet drafts. This packages also includes the drill tool.

This package is known to build and work properly using an LFS-7.6 platform.

Package Information

ldns Dependencies

Recommended

OpenSSL-1.0.1i

Installation of ldns

Install ldns by running the following commands: 

./configure --prefix=/usr     \
            --sysconfdir=/etc \
            --disable-static  \
            --with-drill      &&
make

If you have Doxygen-1.8.8 installed and want to build html documentation, run the following command: 

make doc

This package does not come with a working test suite.

Now, as the root user: 

make install

If you built html documentation, install it by running the following commands as the root user: 

install -v -m755 -d /usr/share/doc/ldns-1.6.17 &&
install -v -m644 doc/html/* /usr/share/doc/ldns-1.6.17

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--with-drill: This option enables building of the drill tool.

--with-examples: This option enables building of the example programs.

--with-pyldns: This option enables building of the Python bindings.
