Re: [sigc] static compile error

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

libsigc++2.2.0 is a 4-year old release. The latest release is 2.2.10.
See http://ftp.gnome.org/pub/GNOME/sources/libsigc++/2.2/

But I'm convinced that you will get same compile errors with 
libsigc++2.2.10.
Did you try the workaround I suggested?

You can try changing
  #include <cstddef>
in sigc++/signal_base.h to
  #include <stddef.h>
and see if you can build libsigc++.
