According to http://www.boost.org/doc/html/signals/ tutorial.html#id1627841 the code above should work? However I can't compile it with VC++ 2005 SP1. Anyone with the same problem? The error message I get is:

The code supporting this feature was accidentally disabled for VC++ in Boost 1.33.1. This oversight was fixed in Boost 1.34.0.

Doug, I upgraded now to Boost 1.34.0 only to run into another problem with Boost.Signal:

[snip error]

If required I can copy&paste the full error message (I only dropped the template parameters for better readability). Is this a known problem? Anything I can do about it?

It appears that we're running into a bug in Visual C++ 7.1's handling of partial ordering of function templates. We'll need to find a workaround and put it into Signals itself; I don't think it can be done without changing the Signals library. Could you report this as a bug at http://svn.boost.org/trac/boost/report ? - Doug
