Waf 1.6
|
|
|
|
Try to detect if the project directory was relocated, and if it was,
|
|
change the node representing the project directory. Just call:
|
|
|
|
waf configure build
|
|
|
|
Note that if the project directory name changes, the signatures for the tasks using
|
|
files in that directory will change, causing a partial build.
