Core Developer Environment (C++)

A discussion on the best way(s) to set up a hoot C++ dev env

[Vladekk]

Here is my take. I think it would be beneficial to allow building and running HN not only in Vagrant, but in the Windows WSL2, with CentOS7 image. It may be these approaches do not differ that much. Both use VMs under the hood.

Right now, I tried to follow this guide
https://github.com/ngageoint/hootenanny/blob/master/docs/developer/HootenannyBuild.asciidoc

But it looks like it is missing some prerequisites that need to be installed on CentOS7 box. I was not able to build HN. I tried running provisioning script first, too, but it did not help.

Current error is:

[root@stone063 hoot]# aclocal && autoconf && autoheader && automake && ./configure --with-services --with-josm
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes

@Vladekk I'm bringing in some other folks who develop on bare metal CentOS and docker who may be able to help out. I actually do develop on Vagrant but agree that its not for everyone. The CentOS part we should be able to help with but don't know how much we'll be able to help with any WSL2 differences, as no one has any experience with it.

I think that particular macro failure states that your environment's compiler isn't set up for C++ 11. Not sure why yours isn't. Maybe there are some compiler switches that need adding?

Thanks, I guessed that much about C++11, but I don't see it in the list of packages. I will try to dig into this more.

I found that my CentOs7 WSL2 install was already messed up by experimenting earlier. I installed a fresh copy and Vagrant provision script is working well now up until PostgreSQL install.

## Working on  localhost
Failed to get D-Bus connection: Operation not permitted
failed to find PGDATA setting in postgresql-13.service

If you have any ideas, that would be appreciated. Meanwhile, I will research some more and get back.

Update: it looks like WSL2 does not support systemd/systemctl yet ;(
