}
按照这种方式编译:
gcc -o spinbutton -g -Wall spinbutton.c `pkg-config --cflags --libs libgnomeui-2.0`
出现了如下的错误：
spinbutton.c: In function ‘main’:
spinbutton.c:75: warning: implicit declaration of function ‘gtk_spin_button_set_shadow_type’
/tmp/cc64C3RP.o: In function `main':

/home/icefly/program/graphics/spinbutton.c:100: undefined reference to `gtk_spin_button_set_shadow_type'

百思不得其解，恳请高手帮助.
