Linker Error Undefined Reference in sign.cpp while building on Ubuntu 23.04

[cversek]

Running Ubuntu 23.04, building from main branch, I get the following error at HYDRA/src/script/sign.cpp:43:

/usr/bin/ld: libbitcoin_common.a(libbitcoin_common_a-sign.o): in function `MutableTransactionSignatureOutputCreator::CreateSig(SigningProvider const&, std::vector<unsigned char, std::allocator<unsigned char> >&, CKeyID const&, CScript const&, SigVersion) const':
.../HYDRA/src/script/sign.cpp:43: undefined reference to `uint256 SignatureHashOutput<CMutableTransaction>(CScript const&, CMutableTransaction const&, unsigned int, int, long const&, SigVersion, PrecomputedTransactionData const*)'

Thanks...
