Waf Tools
|
|
=========
|
|
|
|
Special python modules called Waf **tools** provide functions and classes to help
|
|
using compilers, libraries or programs. The typical usage from a user script is::
|
|
|
|
def function(ctx):
|
|
# ...
|
|
ctx.load('toolname')
|
|
|
|
Where the function is usually:
|
|
|
|
* options: add command-line options used by the tool
|
|
* configure: modify ``conf.env``, raise a configuration error if a prerequisite is not met
|
|
|
|
The tools will usually enhance the application by adding:
|
|
|
|
* new commands deriving from :py:class:`waflib.Context.Context`
|
|
* new task classes deriving from :py:class:`waflib.Task.Task`
|
|
* new methods to :py:class:`waflib.Configure.ConfigurationContext` and :py:class:`waflib.Build.BuildContext` through :py:func:`waflib.Configure.conf`
|
|
* new task generator methods to :py:class:`waflib.TaskGen.task_gen` through :py:func:`waflib.TaskGen.taskgen_method`, :py:func:`waflib.TaskGen.after`
|
|
|
|
As a general rule, existing methods or classes are hardly ever replaced.
|
|
|
|
C/C++ compiler detection
|
|
------------------------
|
|
|
|
The following Waf tools are used for loading specific C or C++ compilers. They may
|
|
be used directly, for example::
|
|
|
|
def options(opt):
|
|
opt.load('compiler_c')
|
|
def configure(conf):
|
|
conf.load('compiler_c')
|
|
|
|
.. toctree::

|
|
tools/clangxx
|

tools/compiler_c
|
|
tools/compiler_cxx
|

|
C/C++ support
|
|
-------------
|
|
|
|
The following modules contain the functions and classes required for building C and C++ applications. They
|
|
are almost always loaded by other Waf tools. Among these, the most important from a user point of view
|
|
is :py:mod:`waflib.Tools.c_config` which provides the :py:func:`waflib.Tools.c_config.check` and
|
|
:py:func:`waflib.Tools.c_config.check_cfg` functions.
|

|
|
tools/c_tests
|

|
|
|
|
Assembly
|
|
--------
|
|
|
|
The following tools provide support for assembly. The module :py:mod:`waflib.Tools.asm` is loaded automatically by :py:mod:`waflib.Tools.nasm` or :py:mod:`waflib.Tools.gas`.
|

|
|
|
|
D language and compilers
|
|
------------------------
|
|
|
|
The first three tools in the following list may be used for detecting D compilers. The remaining contain the support functions and classes.
|
|
|
|
.. toctree::
|
|
|
|
tools/compiler_d
|
|
tools/dmd
|
|
tools/ldc2
|
|
tools/gdc
|
|
tools/d_config
|
|
tools/d
|
|
tools/d_scan
|
|
|
|
Fortran support
|
|
---------------
|
|
|
|
The first four tools in the following list are used for detecting fortran compilers. The three remaining contain the routines for compiling fortran applications.
|
|
|
|
.. toctree::
|
|
|
|
tools/compiler_fc
|
|
tools/g95
|
|
tools/gfortran
|
|
tools/ifort
|
|
tools/fc
|
|
tools/fc_config
|
|
tools/fc_scan
|
|
|
|
C/C++-related applications
|
|
--------------------------
|
|
|
|
The next tools provide support for code generators used in C and C++ projects.
|
|
|
|
.. toctree::
|
|
|
|
tools/bison
|
|
tools/flex
|
|
tools/dbus
|
|
tools/vala
|

tools/glib2
|

Other compilers and tools
|
|
-------------------------
|
|
|
|
.. _extras: https://gitlab.com/ita1024/waf/tree/master/waflib/extras
|
|
|
|
The following tools provide support for specific compilers or configurations. More tools are present in the extras_ folder, although they are not documented and as stable as the default tools.
|
|
