Could someone get this building on Linux?

Probably tonight

Bad news is that it builds perfectly fine for me. The GTK and WPE EWS are both on  still on GCC 6 to ensure compatibility with Debian Stretch.

It looks like the only build errors are on lines 259, 261, 263, and 277 of ContentExtensionParser.cpp, returning a Expected<Optional<Action>, std::error_code>. Maybe you could try making the conversions there more explicit? 

return Expected { Optional { ActionType::BlockLoad }, std::error_code() };

If that doesn't please the EWS and you're really having trouble, I can install Stretch in a VM and fight it there.
