Hide/export symbols in static library

[Jyotirmoy Sharma]

Hi,

Can anyone tell me how I can hide all the global symbols except
for few (i.e. export only selected symbols) while building a static library?

I have tried using "ld -r f1.o f2.o -o lib.a", but this exposes all the global
symbols.

Regards,
