But gmake starts to collect something, albeit a number of warnings, for example:

libi2pd/Tunnel.h:123:17: warning: 'i2p::tunnel::OutboundTunnel::SendTunnelDataMsg' hides overloaded virtual function [-Woverloaded-virtual]
                        virtual void SendTunnelDataMsg (const std::vector<TunnelMessageBlock>& msgs); // multiple messages

As a result, the assembly ended with an error:
