3.3 Compiling OpenLDAP 2
Once the necessary software libraries have been installed and correctly configured, compiling and installing OpenLDAP becomes a matter defining the appropriate options for the configure script and executing the make command. For the sake of simplicity, all examples in this book assume that the root directory for the OpenLDAP installation is /usr/local, which is the default.
Most of the configuration options are set to reasonable defaults or will be set appropriately by the configure script itself. I've already mentioned the —disable-threads option, which you can use if you don't want thread support. You should also be aware of the —enable-wrappers option, which uses the tcp_wrappers libraries for restricting access via the standard /etc/hosts.allow and /etc/hosts.deny. In order to use this option, the tcpd.h header file and libwrap.a library must be installed on a local system.
After extracting the source files using the command:
$ gzip -dc openldap-2.1.8.tar.gz | tar xvf -
go into the newly created directory and execute the ./configure script, defining any options you wish to enable or disable. For example:
$ cd openldap-2.1.8/ $ ./configure --enable-wrappers
Be sure to examine the output that follows this command to verify that the correct DBM libraries were located and any other options you defined were correctly configured. Once you are satisfied with the configuration process, building the OpenLDAP clients and servers is a four-step process:
$ make depend $ make $ make test $ /bin/su -c "make install"
