Using Arduino 1.6.0 and it won't compile. Error log below:

Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

Same here. I followed these guidelines to get rid of most of the errors but the only line of code I can't seem to get the error to go away is this one.

that line needs to be changed to PROGMEM const char* const WebSocketClientStringTable[] =

this is how it should be changed:

const char stringVar[] PROGMEM = "{0}";
const char clientHandshakeLine1[] PROGMEM = "GET {0} HTTP/1.1";
const char clientHandshakeLine2[] PROGMEM = "Upgrade: WebSocket";
const char clientHandshakeLine3[] PROGMEM = "Connection: Upgrade";
const char clientHandshakeLine4[] PROGMEM = "Host: {0}";
const char clientHandshakeLine5[] PROGMEM = "Origin: ArduinoWebSocketClient";
const char serverHandshake[] PROGMEM = "HTTP/1.1 101";

PROGMEM const char* const WebSocketClientStringTable[] =
{
stringVar,
clientHandshakeLine1,
clientHandshakeLine2,
clientHandshakeLine3,
clientHandshakeLine4,
clientHandshakeLine5,
serverHandshake
};

then it compiles fine
