I learned that git submodule update needs to be git submodule update --remote --merge
But, reading more extensively, I realised what I'd been missing. Previously, when looking at the status of the changes, I
thought that git was offering me the option of including all of PoWCore in the main Gapcoin repos ... well, I mean, who wouldn't? ...
On branch v0.9.3-gap
Your branch is up-to-date with 'origin/v0.9.3-gap'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
(commit or discard the untracked or modified content in submodules)
modified: src/PoWCore (new commits, untracked content)
no changes added to commit (use "git add" and/or "git commit -a")
But when I looked at the
actual difference, it was offering to update the

Message:
Update PoWUtils.h
Address compilation failure
which is actually what I wanted.
So I committed the change and the submodule update now works correctly as before, i.e.
git submodule update and
doesn't need the
--remote --merge any longer.
We can all breathe a sigh of relief

Cheers,

Mint uses Boost 1.65 would it still compile on Linux with Boost 1.67?
I have successfully compiled the gapcoin v0.9.3-gap branch on an Ubuntu 19.10 system.
I checked the compilation under Ubuntu 16.04 (the earliest version of Ubuntu still supported) and added (and documented, in doc/build-unix.md) a couple of patches to allow gapcoin-0.9.2 (the official distro) to compile under Ubuntu 16.04.
In gapcoin-0.9.3, I've changed rpcserver.cpp in order to get to compile successfully under Boost 1.67 (and Boost 1.65) and have committed the change (to
https://github.com/gjhiggins/gapcoin.git).
I haven't yet committed the gapcoin-0.9.4 branch that I'm working on.

Thanks for all your efforts, input and hard work on this one Graham (and community !?!) ...
A belated Happy New Year !
I have to migrate some of the servers to new LTS builds and I will be updating the
https://gapcoin.club website with new info.
Anyone for a new windows release with updated SSL etc., ?
Getting very bored of 'slow play time', lets build this community and start to get listed on some additional exchanges etc.,
Again, Gapcoin is going nowhere, except for the record books !
No such thing as an economic point of no return.

P.S. I'm continuing to renew the block explorer, again.
Cheers!
