Set minimum required Boost to 1.47.0 #8920

pull fanquake wants to merge 2 commits into bitcoin:master from fanquake:set-minimum-boost changing 2 files +6 −3

Boost is on the way out, but in the mean time, having the minimum set to 1.20.0 is misleading, and can lead to issues like #8868.

1.47.0 is the first version to include Chrono. See #8875 for some history.

The serial should reflect the original version used as a base - coming from https://www.gnu.org/software/autoconf-archive/ax_boost_base.html
paveljanik commented at 6:33 AM on October 14, 2016: contributor

So you are updating the file to match and at the same time upgrading the minimal requirement. Please always mention this in the PR text and not hide the first part.

Changes like this should be done in two commits, I think.

Concept ACK, but shouldn't some documentation need updating as well?

concept ACK - though personally I'd prefer passing in this version as a parameter from our configure.ac, if possible, instead of changing this upstream file

If only we had documentation for minimum version requirements, it should be updated. But doesn't look like we do, build-unix only lists the libraries necessary not their minimum supported versions. We've never really kept track of those.
