Warning from verification of RFM_MQTT_GW_24_pub4.ino

[bwanajag]

I get the following warning concerning "deprecated conversion from string constant" when I verify the RFM_MQTT gateway sketch.  Is this something to be concerned about, or is there a fix?

C:\Users\me\Documents\Arduino\RFM_MQTT_GW_24_pub4\RFM_MQTT_GW_24_pub4.ino:121:18: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]



char *subTopic = "home/rfm_gw/sb/#";  // MQTT subscription topic ; direction is southbound




C:\Users\me\Documents\Arduino\RFM_MQTT_GW_24_pub4\RFM_MQTT_GW_24_pub4.ino:122:20: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]



char *clientName = "RFM_gateway";  // MQTT system name of gateway

No, as computourist (key source of our programming) wrote here

these warnings [warning: deprecated conversion...] do not interfere with normal functioning of the gateway..
Arduino IDE switched to a different compiler, that's all.
