Building and installing from source

While libreswan is becoming part of more Linux distributions over time, it has not yet made it in all distributions. If your OS does not yet ship with libreswan packages, you can build libreswan from source yourself. The source archive contains a directory /packaging that provides the build instructions for many systems, including fedora, rhel/centos and openwrt. For Debian and Ubuntu based systems, packaging files are in the /debian/ directory.

Here is simple procedure to build debian package from libreswan tarball.

1. cd libreswan-3.*/debian
2. make deb
