Betreff: Re: [Libbitcoin] Trying to compile latest version2 commit fails with 'secp256k1_context_t' has not been declared, how fix? Thanks!
Because the secp256k1 interface has not been stable and the
implementation not versioned, we build from a fork. This will change
once the lib stabilises. See:

https://github.com/libbitcoin/libbitcoin/blob/master/install.sh#L563
