How to make SCons update installed files inside a directory that have changed?

Question

I'm doing:

data = env.InstallAs('$PREFIX/share/odysi', 'data')
env.Alias('install', data)

Which works fine the first time. But if I change something inside the 'data' folder and do scons -Q install again, it says ``install' is up to date.` even though a file has changed and needs to be reinstalled.

There are a lot of files in the directory (and sub directories) so if I can avoid explicitly listing them, that would be best. Tips?

Answer 1

This should do the trick:

files = Glob('data/*.*')
data = env.Install('$PREFIX/share/odysi', files)
env.Alias('install', data)

It needs at least SCons 1.0.1 for Glob support.
