[Scons-users] How to rebuild if target changes

[Непомнящий Евгений Игоревич]

Hello!

I have sconstruct:
------
env = Environment(tools=['textfile'])
env.Textfile('test.h', ['test1'])
------

If I run it, I get file test.h.

But If I change file test.h manually and run scons, I receive message
" `.' is up to date. "

How to tell scons to rebuild file, if it changes since last build?

z:\fillTest>scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
Creating 'test.h'
scons: done building targets.

z:\fillTest>type test.h
test1
z:\fillTest>echo "qweerwterty" >> test.h

z:\fillTest>type test.h
test1"qweerwterty"

z:\fillTest>scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.

z:\fillTest>type test.h
test1"qweerwterty"


Thank you!
