What does it mean? Is it still working?.

In my application the compiling process will proceed without any errors,
but the linker produces the following errors:

Any idea for me?

but i get still these undefined symbol error massages from the linker:

Thank you,

I forgot to put cx.obj and x32.lib into the Linklist.
It works fine with the following Linklist.:

cx.obj+
File1.OBJ+
File2.OBJ+
x32.lib
