symbol

I have a ELF shared object with a symbol initialized to a value. I want to know what the value of a symbol is.

I know objdump -T will give me the symbol's address and length but I need the value:

$ arm-linux-androideabi-objdump -T libcrypto.so.1.0.0 | grep -i FIPS_signature
001a9668 g    DO .bss   00000014 FIPS_signature

However, hexdump knows nothing about ELF sections, offsets and virtual addresses, so I can't use the information:

$ hexdump -v -x -n 0x14 -s 0x001a9668 libcrypto.so.1.0.0
$

How do I dump the value of the symbol?
