Only one tip actually. If you try to build with SCons you have to configure your
environment in 2 places, the SConstruct file and the the
environment,py file. The
reason is that the SConstruct files runs the SWIG_generator.py file
which in turn
imports environment.py. I already reported this and it will be
resolved in the near
future.
When I run SCons, it runs OK quit far, however it fails at somewhere
at the end where
it wants to build the wrapper for some X.. header (don't remember the
exact name).
Tonight I will try to solve the SCons/SWIG annoyance that every
wrapper is regenerated
when only a single change is made.
Good luck,
Marco
