Java support
|
||||
|
||||
Javac is one of the few compilers that behaves very badly:
|
||||
|
||||
#. it outputs files where it wants to (-d is only for the package root)
|
||||
|
||||
#. it recompiles files silently behind your back
|
||||
|
||||
#. it outputs an undefined amount of files (inner classes)
|
||||
|
||||
Remember that the compilation can be performed using Jython[1] rather than regular Python. Instead of
|
||||
running one of the following commands::
|
||||
|
||||
./waf configure
|
||||
python waf configure
|
||||
|
||||
You would have to run::
|
||||
|
||||
java -jar /path/to/jython.jar waf configure
|
||||

||||
