That also gave me compilation errors:

..\Dependency\boost\boost/spirit/home/karma/generate.hpp(72) : error
C2664: 'boost::mpl::assertion_failed' : cannot convert parameter 1
from 'boost::mpl::failed ************(__thiscall
boost::spirit::karma::generate::error_invalid_expression::*
***********)(Expr)' to 'boost::mpl::assert<false>::type'

..\Dependency\boost\boost/spirit/home/karma/generate.hpp(76) : error
C2039: 'generate' : is not a member of
'boost::proto::exprns_::expr<Tag,Args,Arity>'

Below, please find a minimal example.
Thank you for your continued help!

Best,
Dee
