Hi,

Just want to know *exactly* how to use boost::signals in a Qt
project. I read this : http://www.boost.org/doc/html/ch06s04.html
but I don't understand how to do it.
      

First, you should try the attached patch to libs/signals/build/Jamfile 
in order to get the right settings when building the signals library 
(and maybe run the tests ;-) )
You can replace boost_signals with signalslib, of course.

  

I try to recompile boost with :
"-sBUILD=<define>BOOST_SIGNALS_NAMESPACE=signalslib".
      

which compile / toolset ? even: which bjam ? Please post the complete 
commandline next time ;-)

  

After that, I try to directly change BOOST_SIGNALS_NAMESPACE in
signals_common.hpp but didn't work neither.
      

Are you #defining BOOST_SIGNALS_NAMESPACE to signalslib when you're
building your application? Some indication of how it failed would
help.
    

Yes, this is needed, of course.

Some more output would be helpful.

Yours,

Jürgen
