ECDSA_SIG not works

Good morning everyone,

I have problems with the OpenSSL ECDSA ,specifically with the EDSA_SIG struct. When I initialize the struct and I access to its params (r and s) I get the following error: "error: invalid use of incomplete typedef 'ECDSA_SIG' {aka 'struct ECDSA_SIG_st'}". I am using the latest version of OpenSSL (3.0.7)

any tips of why it could happen?

Thanks a lot, Fernando.
