When the 'path' argument was given at TaskGen creation, it was not taken into account for attributing idx (the path of the build context was). This is an issue when creating task generators from a waf tool because their idxs were attributed as if they were in the project root directory, even if another path was specified, which could lead to output files collisions. |

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 and in the API docs
- 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 and by open-source projects such as RTEMS. Learn more about Waf by reading The Waf Book.
For researchers and build system writers, Waf also provides a framework for creating custom build systems and package distribution systems.
Download the project from our page on waf.io or from a mirror on freehackers.org, consult the manual, the API documentation and the showcases and experiments.
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:
$ ./waf-light configure build
Or, if several python versions are installed:
$ 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:
$ ./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:
$ ./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):
$ ./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:
cp waf demos/c/
cd demos/c/
./waf configure build
