Compiler error when using WebServer

Troubleshooting
1

Hi,

I have a very simple program:

#include <WebServer.h>
#include  <spark_wiring_i2c.h>
#include <application.h>
void setup() {
}
void loop() {
}

which results in the following. Any suggestions on how to correct?

Thanks!

What system version are you targeting?
You shouldn’t need #include <spark_wiring_i2c.h>

It looks like your source file name is test1.cpp. When you use a .cpp file (instead of a .ino file) you must include particle.h first, as in:

#include "Particle.h"
#include "WebServer.h"

You can leave out the other two.

@rickkas7 Perfect! Thanks for the quick help. Not really sure what is going on as the file where I’m really using the headers does end in ino. Regardless your solution worked.
