Closed bngesp closed 5 years ago

bngesp commented 5 years ago

After cloning with git i use this command cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DTRANSMISSION_PROTOCOL=TELNET

then I have the following output error when i try to do make linux-mqtt-sn-gateway.

Resolved !!

I just have to modify the LinuxTelnetSocket.h file and change <string.h> to <string>
