Dear Kjell and list, I'd like FOSS, so thank you for your mention about LGPL and static compilation. My problem was solved. i have seriously question: There are many library such as Qt, GTK, boost, and many heavy framework have sigslot. But our system should port to embedded systems. Also it must work under Android (dirty OS) and iOS.So we need to a library that work under them.libsigc++ can work under them? --mohsen On Mon, 2012-07-30 at 20:25 +0200, Kjell Ahlstedt wrote: > libsigc++2.2.0 is a 4-year old release.
