Re: [gtkmm] Newbie in gtkmm and c++ under linux

You need to also compile helloworld.cc, IE:

g++ main.cc helloworld.cc -o helloworld `pkgconfig gtkmm-2.0 --libs
--clfags`

Oh, and I had problems following the gtkmm-2.4 guide while using
gtkmm-2.0.

>From the tutorial on the web it says:
m_button.signal_clicked().connect(sigc::mem_fun(*this,
&HelloWorld::on_button_clicked));

I got an error about an undeclared reference to 'sigc' when I tried
compiling to that, if I remember correctly.

But in the tutorial in /usr/share/docs/gtkmm-2.0/ the Hello World
tutorial says to do:

m_button.signal_clicked().connect(SigC::slot(*this,
&HelloWorld::on_button_clicked));

Which worked fine. I'm not sure why that is, maybe someone can explain
it to me?
