|Make sure no strongSwan-related distribution packages are installed before building and installing strongSwan from sources
strongSwan should run on most distros' kernels. If you build your own kernel, include the required kernel modules.
The GNU build system (Autotools) is used to build strongSwan. There is an ever
growing list of
./configure options available.
|Many of these configuration options are enabled by default. Thus please use ./configure --help to check which options are actually available for your strongSwan release.
Refer to the list of plugins to learn more about the plugins enabled with the above options.
|Some plugins have dependencies on third-party libraries. To compile these plugins, the header files of those libraries are required. Make sure these are installed on your system, e.g. by installing the appropriate -dev package on Debian-based systems. Otherwise, the configure script will complain that it can’t find the library or header files.
The build procedure is as with any autotools project:
Unpack the tarball and navigate into the directory:
tar xjf strongswan-x.x.x.tar.bz2 cd strongswan-x.x.x
Configure strongSwan using the available options:
./configure --prefix=/usr --sysconfdir=/etc --<your-options>
Build the sources and install the binaries as root:
make sudo make install
To build strongSwan from the Git repository, additional tools and steps are
HACKING for details.
Plugins can be included in their associated library in
a so called monolithic build (
--enable-monolithic). That way it’s not necessary
to distribute separate shared object files for each plugin but only the major
libraries and executables. The plugins that are loaded at runtime may still
be controlled with the options described here.
Since version 5.5.3 a static build that only relies on third-party libraries, i.e. in which our own libraries and plugins are all statically linked into the executables can be achieved by configuring with
--disable-shared --enable-static --enable-monolithic
Including third-party static libraries requires manual modification of the Makefiles
due to limitations of our build system (see e.g. the Makefile for the fuzzing
