Hi Niall,
What is the boost version you are running on your Cent OS?
Yesterday I removed all boost installations and from my other Ubuntu, 16.04 LTS and got similar issues as on RedHat with this 1.66 version. Do you think it is related to the version or rather the way I try to compile/ install that without root privileges?
Tonight I will try as you do it in your Docker images https://github.com/OpenSourceRisk/Engine/tree/master/Docker
Regards,
Wojtek
