They are also included while building mem.so.But I got the mistake.
I didnt define the virtual methods declared in X and Y out of pure

Doesnt it sound right if we have some error or warning thrown for such

Since it didnt throw anything during build, I thought my lib is as good
as any that of experts'!

I dont even know what a shared lib should contain]
