make-ca-1.13 and libpcap-1.10.4 (for example programs), Python-2.7.18 and SWIG-4.1.1 (for Python bindings), and Doxygen-1.9.8 (for html documentation)
Install ldns by running the following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--disable-static \
--with-drill &&
makeIf you have Doxygen-1.9.8 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-1.8.3 && install -v -m644 doc/html/* /usr/share/doc/ldns-1.8.3
--disable-static: This switch prevents
installation of static versions of the libraries.
--with-drill: This option enables building of the
drill tool (used for obtaining debug information
from DNS(SEC))
--disable-dane-ta-usage: This option disables DANE-TA
(DNS-Based Authentication of Named Entities) support. It is only needed
if OpenSSL-1.1.0 or later is not installed.
--with-examples: This option enables building of the
example programs.
--with-pyldns: This option enables building of the Python
bindings.
