Python dependency, documentation and tests
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
FRR's documentation and basic unit tests heavily use code written in Python.
|
||||
Additionally, FRR ships Python extensions written in C which are used during
|
||||
its build process.
|
||||
|
||||
To this extent, FRR needs the following:
|
||||
|
||||
* an installation of CPython, preferably version 3.2 or newer (2.7 works but
|
||||
is end of life and will stop working at some point.)
|
||||
* development files (mostly headers) for that version of CPython
|
||||
* an installation of `sphinx` for that version of CPython, to build the
|
||||
documentation
|
||||
* an installation of `pytest` for that version of CPython, to run the unit
|
||||
tests
|
||||
|
||||
The `sphinx` and `pytest` dependencies can be avoided by not building
|
||||
documentation / not running ``make check``, but the CPython dependency is a
|
||||
