Subject: [dpdk-dev] [PATCH 1/8] doc: update Linux GSG system requirements section
Date: Fri, 22 Nov 2019 16:03:52 +0000
Message-ID: <20191122160359.11625-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20191122160359.11625-1-bruce.richardson@intel.com>

Update the system requirements section of the doc to cover builds with
meson and ninja. This involves updating the package dependencies to include
meson, ninja and python 3.5, and also updating the optional dependencies
section to explain that the components are enabled/disabled automatically
by meson.

As part of this update, the relevant sections were simplified to keep the
document shorter. For mandatory requirements, we can refer to the various
distro's development tools package groups rather than requiring gcc, core
tools etc. individually. The optional package list was very incomplete, and
if complete would duplicate information in the individual driver's guides.
Therefore we can simplify it by listing only the library optional
requirements and referring users to the driver docs to find details on
their dependencies.

+**Additional Libraries**
+
+A number of DPDK components, such as libraries and poll-mode drivers (PMDs) have additional dependencies.
+For DPDK builds using meson, the presence or absence of these dependencies will be
+automatically detected enabling or disabling the relevant components appropriately.
+
+For builds using make, these components are disabled in the default configuration and
+need to be enabled manually my changing the relevant setting to "y" in the build configuration file
+i.e. the ``.config`` file in the build folder.
+
+In each case, the relevant library development package (``-devel`` or ``-dev``) is needed to build the DPDK components.
+
+For libraries the additional dependencies include:
+
+*   libarchive: for some unit tests using tar to get their resources.
+
+*   jansson: to compile and use the telemetry library.
+
+*   libelf: to compile and use the bpf library.

+For poll-mode drivers, the additional dependencies for each driver can be
