Arduino library dependencies

Hi,

Last question of the day, I promise.

I'm trying to encapsulate the Grove Ultrasonic Library in my library but getting nowhere.

How can I add the Ultrasonic library as a dependency of my library so that I can add an Ultrasonic object as a private member of my class, thus hiding it from the user sketch?

Tried everything I could think of but getting loads of compile errors that make no sense to me.

For now, I'm just keeping it outside which will work but not what I want.


Many thanks

Pete...

You should be able to use the "depends" attribute in the library.properties to ensure the other library is installed when yours is:
e.g. depends=Arduino_GroveI2C_Ultrasonic

Thanks for that - but how do I add it as a dependency in the Library project (or add any library as a dependency) so that I don't keep getting "undefined" errors like the ones I am getting for Servo and QTRSensors in the picture. The project still compiles/uploads so is ok but development time dependencies aren't there.

Many thanks

Pete...

Sorry -here it is. I guess I'm looking how to set the build paths?

1)
You must be using older visual micro version. please also switch on vMicro>Compiler>verbose and post the output again. In newer releases enabling build properties also switched on verbose.

2)
You should also ensure you have an #include <other_lib.h> in your library .cpp file. Adding includes to .h files will not be auto discovered.

3)
Of course, the project code such as .ino will need #include <your_lib.h>
