Compiling and Installing DPDK System-wide
-----------------------------------------
DPDK can be configured, built and installed on your system using the tools
``meson`` and ``ninja``.
-.. note::
-
- The older makefile-based build system used in older DPDK releases is
- still present and its use is described in section
- `Installation of DPDK Target Environment using Make`_.
DPDK Configuration
~~~~~~~~~~~~~~~~~~
dpdk = dependency('libdpdk')
sources = files('main.c')
executable('dpdk-app', sources, dependencies: dpdk)
-
-
-Installation of DPDK Target Environment using Make
---------------------------------------------------
-
-.. note::
-
- The building of DPDK using make will be deprecated in a future release. It
- is therefore recommended that DPDK installation is done using meson and
- ninja as described above.
-
-The format of a DPDK target is::
-
- ARCH-MACHINE-EXECENV-TOOLCHAIN
-
-where:
-
-* ``ARCH`` can be: ``i686``, ``x86_64``, ``ppc_64``, ``arm64``
-
-* ``MACHINE`` can be: ``native``, ``power8``, ``armv8a``
-
-* ``EXECENV`` can be: ``linux``, ``freebsd``
-
-* ``TOOLCHAIN`` can be: ``gcc``, ``icc``
-
-The targets to be installed depend on the 32-bit and/or 64-bit packages and compilers installed on the host.
-Available targets can be found in the DPDK/config directory.
-The defconfig\_ prefix should not be used.
-
-.. note::
-
- Configuration files are provided with the ``RTE_MACHINE`` optimization level set.
- Within the configuration files, the ``RTE_MACHINE`` configuration value is set to native,
- which means that the compiled software is tuned for the platform on which it is built.
- For more information on this setting, and its possible values, see the *DPDK Programmers Guide*.
-
-When using the Intel® C++ Compiler (icc), one of the following commands should be invoked for 64-bit or 32-bit use respectively.
-Notice that the shell scripts update the ``$PATH`` variable and therefore should not be performed in the same session.
-Also, verify the compiler's installation directory since the path may be different:
-
-.. code-block:: console
-
- source /opt/intel/bin/iccvars.sh intel64
- source /opt/intel/bin/iccvars.sh ia32
-
-To install and make targets, use the ``make install T=<target>`` command in the top-level DPDK directory.
-
-For example, to compile a 64-bit target using icc, run:
-
-.. code-block:: console
-
- make install T=x86_64-native-linux-icc
-
-To compile a 32-bit build using gcc, the make command should be:
-
-.. code-block:: console
-
- make install T=i686-native-linux-gcc
-
-To prepare a target without building it, for example, if the configuration changes need to be made before compilation,
-use the ``make config T=<target>`` command:
-
-.. code-block:: console
-
- make config T=x86_64-native-linux-gcc
-
-.. warning::
-
- Any kernel modules to be used, e.g. ``igb_uio``, ``kni``, must be compiled with the
- same kernel as the one running on the target.
- If the DPDK is not being built on the target machine,
- the ``RTE_KERNELDIR`` environment variable should be used to point the compilation at a copy of the kernel version to be used on the target machine.
-
-Once the target environment is created, the user may move to the target environment directory and continue to make code changes and re-compile.
-The user may also make modifications to the compile-time DPDK configuration by editing the .config file in the build directory.
-(This is a build-local copy of the defconfig file from the top- level config directory).
-
-.. code-block:: console
-
- cd x86_64-native-linux-gcc
- vi .config
- make
-
-In addition, the make clean command can be used to remove any existing compiled files for a subsequent full, clean rebuild of the code.
-
-Browsing the Installed DPDK Environment Target
-----------------------------------------------
-
-Once a target is created it contains all libraries, including poll-mode drivers, and header files for the DPDK environment that are required to build customer applications.
-In addition, the test and testpmd applications are built under the build/app directory, which may be used for testing.
-A kmod directory is also present that contains kernel modules which may be loaded if needed.
