## ABOUT WAF
|
|
|
|
Waf is a Python-based framework for configuring, compiling and installing applications. Here are perhaps the most important features of Waf:
|
|
|
|
* *Automatic build order*: the build order is computed from input and output files, among others
|
|
* *Automatic dependencies*: tasks to execute are detected by hashing files and commands
|
|
* *Performance*: tasks are executed in parallel automatically, the startup time is meant to be fast (separation between configuration and build)
|
|
* *Flexibility*: new commands and tasks can be added very easily through subclassing, bottlenecks for specific builds can be eliminated through dynamic method replacement
|
|
* *Extensibility*: though many programming languages and compilers are already supported by default, many others are available as extensions
|
|
* *IDE support*: Eclipse, Visual Studio and Xcode project generators (waflib/extras/)
|
|
* *Documentation*: the application is based on a robust model documented in [The Waf Book](https://waf.io/book/) and in the [API docs](https://waf.io/apidocs/)
|
|
* *Python compatibility*: cPython 2.5 to 3.4, Jython 2.5, IronPython, and Pypy
|

|
|
Waf is used in particular by innovative companies such as [Avalanche Studios](http://www.avalanchestudios.se) and by open-source projects such as [RTEMS](https://www.rtems.org/). Learn more about Waf by reading [The Waf Book](https://waf.io/book/).

For researchers and build system writers, Waf also provides a framework for creating [custom build systems](https://gitlab.com/ita1024/waf/tree/master/build_system_kit) and [package distribution systems](https://gitlab.com/ita1024/waf/blob/master/playground/distnet/README.rst).

## HOW TO CREATE THE WAF SCRIPT
|
|
|
|
Python >= 2.6 is required to generate the waf script, and the resulting file can then run on Python 2.5.
|
|
Just run:
|
|
```sh
|
|
$ ./waf-light configure build
|
|
```
|
|
Or, if several python versions are installed:
|
|
```sh
|
|
$ python3 ./waf-light configure build
|
|
```
|
|
|
|
The Waf tools in waflib/extras are not added to the waf script. To add
|
|
some of them, use the --tools switch. An absolute path can be passed
|
|
if the module does not exist under the 'extras' folder:
|
|
```sh
|
|
$ ./waf-light --tools=swig
|
|
```
|
|
|
|
To customize the initialization, pass the parameter 'prelude'. Here is for example
|
|
how to create a waf file using the compat15 module:
|
|
```sh
|
|
$ ./waf-light --tools=compat15 --prelude=$'\tfrom waflib.extras import compat15\n'
|
|
```
|
|
|
|
Although any kind of initialization is possible, using the build system kit
|
|
may be easier (folder build\_system\_kit):
|
|
```sh
|
|
$ ./waf-light --make-waf --tools=compat15,/comp/waf/aba.py --prelude=$'\tfrom waflib.extras import compat15\n\tprint("ok")'
|
|
```
|
|
|
|
To avoid regenerating the waf file all the time, just set the `WAFDIR` environment variable to the directory containing "waflib".
|
|
|
|
## HOW TO RUN THE EXAMPLES
|
|
|
|
Try this:
|
|
```sh
|
|
cp waf demos/c/
|
|
cd demos/c/
|
|
./waf configure build
|
|
```
