Problem in connecting signal handler with gtk_builder in C++ code

["PT SWing" <pentie gmail com>]

Hi, all:

I knew gtk+ was a C builded technic, but now i have to use it in C++ codes, and the problem i encountered is that, i use gtk_builder_connect_signals to connect all the widgets from the xml to the handler function, just as what micahcarrick's tutorial do in C, and complied and link it with -export-dynamic, 

$ g++ entry.cpp `pkg-config --libs --cflags gtk+-2.0` -export-dynamic

no problem happens. 

But when i run it, the program just couldn't find the handler function, reporting :

pentie pentie-desktop:~/Programming/linux/entry$ ./a.out 

(a.out:12605): Gtk-WARNING **: Could not find signal handler 'on_window_destroy'

(a.out:12605): Gtk-WARNING **: Could not find signal handler 'on_exit_clicked'

(a.out:12605): Gtk-WARNING **: Could not find signal handler 'on_add_clicked'
^C

I knew there must be something different with the g++ linker and the -export-dynamic, but i have no clue how to solve this.

Thanks so much if anyone could give me a hand on this. thanks

ps: a simple test code was in the attach file. you will find that the c_style code works very well, but not the cpp one.........
