Dear Eric,
This error has been reintroduced in the "version2" repo, in the
currenetly latest commit which is
https://github.com/libbitcoin/libbitcoin/blob/e3a2f8213c939adead02923fdca6f891975632d4/examples/main.cpp
.
I.e. kindly remove the four lines 45-48?
At least doing that makes compilation work.
Thanks!
