INSTALLATION INSTRUCTIONS FOR GVM-LIBS

Please note: The reference system used by most of the developers is Debian GNU/Linux 'Bullseye' 11. The build might fail on any other system. Also, it is necessary to install dependent development packages.

Prerequisites for gvm-libs

See at the end of this section how to easily install these prerequisites on some supported platforms.

General build environment:

  • a C compiler (e.g. gcc)
  • cmake >= 3.0
  • pkg-config

Specific development libraries:

  • libglib >= 2.42 (all)
  • libgio >= 2.42 (util)
  • zlib >= 1.2.8 (util)
  • libgpgme >= 1.7.0 (util)
  • libgnutls >= 3.2.15 (util)
  • libuuid >= 2.25.0 (util)
  • libssh >= 0.6.0 (util)
  • libhiredis >= 0.10.1 (util)
  • libxml2 >= 2.0 (util)
  • libnet1 >= 1.1.2.1 (boreas)
  • libpcap
  • libgcrypt
  • libpaho-mqtt >= 1.3.0 (utils)

Prerequisites for building documentation:

  • doxygen
  • xmltoman (optional, for building man page)

Prerequisites for building tests:

  • Cgreen (optional, for building tests)

Install prerequisites on Debian GNU/Linux 'Bullseye' 11:

apt-get install \
cmake \
pkg-config \
libglib2.0-dev \
libgpgme-dev \
libgnutls28-dev \
uuid-dev \
libssh-gcrypt-dev \
libhiredis-dev \
libxml2-dev \
libpcap-dev \
libnet1-dev \
libpaho-mqtt-dev

Prerequisites for Optional Features

Certain features of gvm-libs are optional and require the following:

Prerequisites for LDAP authentication:

  • libldap2 library >= 2.4.44 (util) (Debian package: libldap2-dev)

Prerequisites for RADIUS authentication:

  • libradcli4 library >= 1.2.6 (util) (Debian package: libradcli-dev)
  • Alternative: libfreeradius3 library (util) (Debian package: libfreeradius-dev)

Install prerequisites for optional features on Debian GNU/Linux 'Buster' 10:

apt-get install \
libldap2-dev \
libradcli-dev

Compiling gvm-libs

If you have installed required libraries to a non-standard location, remember to set the PKG_CONFIG_PATH environment variable to the location of your pkg-config files before configuring:

export PKG_CONFIG_PATH=/your/location/lib/pkgconfig:$PKG_CONFIG_PATH

Create a build directory and change working directory into it with

    mkdir build && cd build

Afterwards you can run cmake with different options:

  • Configure gvm-libs build with a custom installation path:

      cmake -DCMAKE_INSTALL_PREFIX=/path/to/your/installation ..

  • or (if you want to use the default installation path /usr/local):

      cmake ..

  • Configure gvm-libs build with tests, you need to run cmake with BUILD_TESTS:

      cmake -DBUILD_TESTS=ON ..

The cmake command only needs to be executed once. Further information regarding cmake can be found here or with the command cmake --help-full. You can list all project options and settable variables with cmake -LA.

Thereafter, you need to compile and install the project with make. The following command options are available:

make                # build the libraries
make help           # list possible make commands
make doc            # build the documentation
make doc-full       # build more developer-oriented documentation
make tests          # build tests (requires BUILD_TESTS activated)
make install        # install the build
make rebuild_cache  # rebuild the cmake cache
make format         # code style and formatting

Please note that you may have to execute make install as root, especially if you have specified a prefix for which your user does not have full permissions.

You can also install specific components with make. See make help for more details. You can remove the compiled binaries with make clean.

To clean up the full build environment, simply remove the contents of the build directory you created above.

cd .. && rm -rf build

Configurable Options

During compilation, the build process uses a set of compiler options which enable very strict error checking and asks the compiler to abort should it detect any errors in the code. This is to ensure a maximum of code quality and security.

Some (especially newer) compilers can be stricter than others when it comes to error checking. While this is a good thing and the developers aim to address all compiler warnings, it may lead the build process to abort on your system.

Should you notice error messages causing your build process to abort, do not hesitate to contact the developers using the Greenbone Community Portal. Don't forget to include the name and version of your compiler and distribution in your message.

Building GVM Libraries statically linked

If you want to build a statically linked version -- for example to subsequently build a statically linked program using this library -- you need statically linked versions of the prerequisite libraries as well.

This can be a problem with current versions of the GnuTLS library. In most distributions GnuTLS is built with p11-kit support, which makes linking statically against the GnuTLS library impossible. To work around this, you can build the GnuTLS yourself after configuring it without support for p11-kit. This can be done with the following parameters:

./configure --disable-shared --enable-static --without-p11-kit

Note that you will most likely want to add additional parameters to configure the GnuTLS library based on your distributions policy and/or your personal needs, e.g. the correct prefix so the statically linked version will be found. The make install command will then build the GnuTLS library and install it into the path you configured.

Once you have built and installed the GnuTLS library, configure this module with the following parameters to request statically linked versions of the single library modules:

cmake -DBUILD_STATIC=1 -DBUILD_SHARED=0 ..

Once again, the make install command will build and install the requested modules.
