Error Compilling For board ESP8266 Generic Module

[manharjoshi]

i am uploading sketch given below to my esp wroom-02 board. it is downloaded from here only. it is showing error like this Error Compilling For ESP8266 Generic Module. showing same error for NodeMCU(12-E).how to solve this.thanks in advance

`//************************************************************ // this is a simple example that uses the easyMesh library // // 1. blinks led once for every node on the mesh // 2. blink cycle repeats every BLINK_PERIOD // 3. sends a silly message to every node on the mesh at a random time betweew 1 and 5 seconds // 4. prints anything it recieves to Serial.print // // //************************************************************ #include <easyMesh.h>
