Compile fails on Ubuntu & Linux in general

[kf6kjg]

This is due to updating to Boost 1.66.0 from the previously required Boost 1.55.0. The oldest available in Conan is 1.66.0, hence the change, but this is causing breakage - but only on the Ubuntu Linux build.

At the moment the CI is set to ignore failures in the Ubuntu build. I want this reversed, but the Boost change issue needs resolution first.

I get the following error when trying to compile whip from master branch.

Not sure where to look for the resolution.

That's the error I was mentioning. If you manually set up and install Boost 1.55.x correctly, no mean feat on its own, then you can compile successfully. This I've done locally on my computer, but it was... difficult to get right.

The real fix is to modernize the WHIP code to use C++17 and newer versions of Boost. That'll take a bit of effort.
