I need some help getting started with the .FIT SDK in XCode. I'm just trying to get the example to run and have 37 linker errors!

Hello WillLuce,

I cannot reproduce the linker errors you are seeing. Have you made sure to include and compile the .cpp files for the message broadcasters you are using? (i.e, fit_mesg_broadcaster.cpp ).

If you have already done this or it does not fix the issue, feel free to send your project files to me through a private message or attach them in this thread and I will take a look at them.

Ok. For some reason, the PM option isn't showing up for me on this website. Anyway, here are the steps I've taken.

1. Created a new Xcode project

3. Added all of the .cpp and .hpp files to the
compile sources 


4. Copied all of the code from decode.cpp to the main.cpp in my project

5. Added a TestActivity.fit to my directory and to the arguments of my build scheme

When I run, it compiles. But, when it gives me an "Error opening TestActivity.fit"

It's not letting me attach my project files here.
