Hi,
I am trying to combine sigc++ with C++0x Lambdas, but when using lambdas
returning a value, this desn't seem to work:
Now it works in the new libsigc++ release 2.2.11, provided you use the
new macro SIGC_FUNCTORS_DEDUCE_RESULT_TYPE_WITH_DECLTYPE. See the
documentation of that macro at
http://developer.gnome.org/libsigc++/stable/group__sigcfunctors.html.
If you are eager to use it, you can get the source code from
http://ftp.gnome.org/pub/GNOME/sources/libsigc++/2.2/ or the Git
repository http://git.gnome.org/browse/libsigc++2/.
//sigc::slot<bool, int> try_fun = mem_fun(fun_is_42,
&std::function<bool(int)>::operator()); // also don't seem to work
This works if you replace mem_fun by sigc::mem_fun.
Kjell
