Hi All,
FYI I created a new VM with the proper distribution 20.04LTS. Everything compiled fine. Ubuntu 21.10 was using gcc 11.## not gcc 9.##. I suspect this was the issue.
##################
I am trying to Install Esys -Particle on Ubuntu 21.10 (on VMware Virtual Machine )
I have followed the instructions at "https://answers.launchpad.net/esys-particle/+faq/3234"
I was able to progress all the way through part 3 without issue but failed at the "make" command giving me the following error(s) :
.... error: static assertion failed: comparison object must be invocable as const
770 | is_invocable_v<const _Compare&, const _Key&, const _Key&>
Any help or guidance is appreciated, Saad Haq
