the shared library demands virtual methods?!

You did not mention the architecture. I get

mira% gcc -shared -o t.so t.C
mira% gcc -o t -v t.so       
Reading specs from /usr/lib/gcc-lib/i486-pc-linux-gnu/egcs-2.91.42/specs

/usr/lib/crt1.o(.text+0x16): undefined reference to `main'
collect2: ld returned 1 exit status

which looks fine to me.
