Web IDE - including a library

General
1

I’m having a bit of trouble using the TimeAlarms library on the Web IDE. When I add the library automatically (via the “include in app” button) the program compiles fine:

// This #include statement was automatically added by the Particle IDE.
#include "TimeAlarms/TimeAlarms.h"

When I try to create my own .h and .cpp file to include the library manually, I get compile errors:

// This #include statement was automatically added by the Particle IDE.
#include "TimeAlarms.h"

(The reason why I want to include the library manually is because I need to edit the .cpp file to allow for more alarms. The default is 6 for this library and I need 8.)

I am also using these two additional libraries:

// This #include statement was automatically added by the Particle IDE.
#include "OneWire/OneWire.h"
// This #include statement was automatically added by the Particle IDE.
#include "RCSwitch/RCSwitch.h"

I’m not quite sure what I am doing wrong. The same program runs fine when compiled via the desktop IDE however I’m having a bit of trouble getting things to work properly on the web IDE. Any help/ideas would be appreciated.

What’s the error output :o?

I’m not quite sure I’m understanding what it is telling me but here it is:

That's the one. If you include it through the library system, you need the 'double' name: "yadayada/yadayada.h", whereas you'd need the single include if you include the files manually: "yadayada.h"

Give that a shot :)?

Sorry, I had posted the wrong output. I edited the post above just now to reflect the error output I get with the following includes:

#include "TimeAlarms.h"
#include "OneWire.h"
#include "RCSwitch.h"

The OneWire and RCSwitch both seem fine when I added them manually instead of through the system library. The TimeAlarms seems to be giving me the trouble.

With an empty sketch, including those files manually seems to work fine. Do mind the capitalization of the file names, they might make a difference.
It might be something in your code that’s being problematic.

Okay so it seems I caused my own error and it’s unrelated to the import. :grimacing:

Just problems with the rest of my program. All seems to be working now.
