{{{
Knot DNS build system relies on these standard tools:
    make
    libtool
    autoconf >= 2.65
}}}

== Required libraries ==
libknotを作るだけなので、気にしなくてもいいのかも。

Knot DNS requires few libraries to be compiled:
{{{
    GnuTLS, at least 3.3
    Jansson, at least 2.3
    Userspace RCU, at least 0.5.4
    libedit
    lmdb (included)
    libcap-ng, at least 0.6.4 (optional)
    libidn (optional)
    libsystemd (optional)
    protobuf-c and fstrm (optional)
}}}
