Hi @dbdxnuliba,

Please follow the provided bug report template. Also, group related compiler issues (#13, #14) in a single ticket.

As described in the prerequisites section of the documentation, Ubuntu Xenial 16.04 does not satisfy the requirements. Please make sure your system satisfies the mentioned requirements. Consider running OCS2 in a container if you are not able to update your system.
