Need help on Gtk--

[Chowdhury Takdir Hossain <takdir dblab is tsukuba ac jp>]

Hello there 
I have just finished the installation of both gtk+-1.0.6 and Gtk--(0.9.16)
on my Linux machine. Though an error was occured at the end during 
the installation of Gtk--, it seemed to be not a fatal error. It just got 
exited from the (directory_where_Gtk--was_untarred/gtk--/example) directory complaining that there is no 
"Makefile.in". However to verify whether it works, I wrote a trivial program 
with the Gtk-- and had it compiled safely. 

I am now writing a test program with the Gtk-- which launches some 
X clients from the system when the corresponding buttons on it are clicked.
But my gcc(2.8.1) compiler detects an error saying that 
"test.cc:37:conversion from `Signal_proxy0<_GtkObject>' to 
non-scalar type `Signal0' requested/usr/local/include/gtk--sigcpp.h:176: in passing argument 1 of `connect_to_function(Signal0 &, void (*)())' "

I have a function call statement connect_to_function(button->clicked,&system,"kterm &")on the line 37 in my source code. 

Another thing is worth mentioning that if I use any local function instead of 
"system" such as connect_to_function(button->clicked,&show_hello), it works 
well! where function show_hello() was difined in the same source code.

Am I missing something in my source code? Or is the error which appeared
during the installation of Gtk-- affecting it?

I have no idea why this is happening. I need your kind advice.
Concrete solution will be appreciated as I am a novice at this stuff.
  
I am looking forward to hearing from someone.


Best regards,
Takdir
