What do you mean, would it be autmoticaly linked like other librarys in
/usr/lib? (sorry, I'm not a c/c++ expert)
> If not, Please check libvirt library by using nm command.
# nm /usr/lib/libvirt.so.0.4.4
nm: /usr/lib/libvirt.so.0.4.4: no symbols
# nm -D /usr/lib/libvirt.so.0.4.4

including

So the libary itself should be ok, and I have only some stupid errors in
the makefile?
