Statically linking GMP

[Steven Beeckman]

Hello,

I have made an application in C++ using GMP, but I need it to be
linked/compiled statically (needs to be run in a simulator called
SimIt-ARM). I'm doing the cross-compilation to ARM in scratchbox (
http://www.scratchbox.org). GMP has been compiled and installed in
Scratchbox.

The command
         g++ -lgmp -static -O3 -o rsa_keygen rsa_keygen.cpp
gives errors about undefined references to __gmpz_init, __gmpz_clear, ...

What is the correct command to get my binary statically linked?

Thanks,
