These unit tests for BIND 9 are based on the NetBSD Automated Test Framework release 0.17. To build an external copy of ATF for use by BIND 9: $ cd atf-src $ configure --prefix=<prefix> --enable-tools --disable-shared $ make $ make install Subsequently, specify the ATF prefix when building BIND 9: $ configure --with-atf=<prefix> ATF can also be built automatically during the BIND 9 build, by specifying --with-atf without an argument: $ configure --with-atf This causes BIND 9 to build ATF in the atf-src directory and link to it directly.
