[Scons-users] Need help to debug, problem with Alias()

[Pierre-Luc Boily]

3.0.5 gives the same error.  I dug a little bit and I found that the
problem might be related with Alias.

1. Following line is being called for .ui files :
env.Default(env.Alias('bin',env.Uic4(src)))

2. And following line is for target returned by Install : env.Alias('bin',
tgts)

So, those 2 lines are called numerous time and it gives the error I was
talking about.  I realized that if I change this
env.Default(env.Alias('bin',env.Uic4(src)))
by this
env.Uic4(src)

This resolved my problem.  Uic4 target is not needed as a Default target.
