Hi, I am running gcc 4.2.3 on ubuntu. I am getting the following error: /home/yinglcs/TestGtkEmbed.cpp:290: undefined reference to `A::setA(int a)' TestGtkEmbed.o: In function `ob_sig_int': /home/yinglcs/TestGtkEmbed.cpp:1172: undefined reference to `A::getA()' Where setA, GetA are static functions of class A. And this is the command I have for compiling TestGtkEmbed. c++ -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wcast-align -Wno-long-long -pedantic -fno-strict-aliasing -fshort-wchar -pthread -pipe -DDEBUG -D_DEBUG -DDEBUG_yinglcs -DTRACING -g -fno-inline -Os -freorder-blocks -fno-reorder-functions -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/gtk-unix-print-2.0 -o TestGtkEmbed TestGtkEmbed.o -lpthread -Wl,-rpath-link,../../../../dist/bin -L../../../../dist/bin -L../../../../dist/lib -lX11 ../../../../dist/lib/libxpcomglue.a -ldl -lm -lgtk-x11-2.0 -latk-1.0 -lgdk-x11-2.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lfontconfig -lXext -lXrender -lXinerama -lXi -lXrandr -lXcursor -lXcomposite -lXdamage -lpango-1.0 -lcairo -lgmodule-2.0 -ldl -lX11 -lXfixes -lgobject-2.0 -lglib-2.0 -lgnet-2.0 TestGtkEmbed.o: In function `main': I suspect that when I compile TestGtkEmbed, i am not linking against A.o and that results in the 'undefined reference to `A::getA()' that i saw. Is that right? If yes, can you please tell me how to fix it? If not, can you please tell me what is the cause of my problem? Thank you.
