Dokimase kai to -shared:

       -shared
           Produce a shared object which can then be linked with
           other objects to form an executable.  Not all systems
           support this option.  For predictable results, you
           must also specify the same set of options that were
           used to generate code (-fpic, -fPIC, or model subop-
           tions) when you specify this option.[1]

Symboyli moy einai na dokimaseis prota na ftiakseis shared lib gia to diko soy
