Arduino compile error

[walchko]

So I cloned mavlink and units into my library folder. When I try to add the header:

#include <mavlink.h>

I get the following warnings and errors about elapsedMillis (and others) not being types ... am I missing something?

[walchko]

Adding elapsedMillis from here https://github.com/pfeerick/elapsedMillis I thought would help, but it isn't.

[walchko]

Also have these warnings:

/Users/kevin/Documents/Arduino/libraries/units/src/constants.h:44:20: warning: variable templates only available with '-std=c++14' or '-std=gnu++14'
   44 | static constexpr T G_MPS2 = static_cast<T>(9.80665);

I don't think your units (https://github.com/bolderflight/units) will compile on Arduino. Or is there a way around this c++14 thing?

[walchko]

OK, so I got it to compile, but there are a ton of warnings. I did this, which might not be the best solution.

#if defined(ARDUINO)
#include "Arduino.h"
#include "optional.hpp"  // NOLINT
#include <elapsedMillis.h> // <- added this
#else
#include <optional>
#include "core/core.h"
#endif

all of the remaining warnings:

Thanks, I use Teensy a ton and got spoiled having elapsedMillis. This is the Teensy implementation:
https://github.com/PaulStoffregen/cores/blob/master/teensy/elapsedMillis.h

I'll have to look more into the template issues with the Units library. Tough having different Arduino boards using different g++/gcc compiler versions. I think it's mostly used here for radian <-> degree conversions.

Lot's of warnings are expected. This is from the C MAV Link message implementation (https://github.com/mavlink/c_library_v2), which this library wraps around.

#include <elapsedMillis.h>

I tried this. Using the example, I could not get anything to compile.

Compiling on Arduino for STM32, I get:

I get the following error related:
E:\Documents\Arduino\libraries\mavlink-main\src\heartbeat.h:101:3: error: 'elapsedMillis' does not name a type
101 | elapsedMillis heartbeat_timer_ms_;

When I compile for pure arduino (Mega/Arduino/mini etc), I get the following:
E:\Documents\Arduino\libraries\mavlink-main\src/mavlink.h:35:10: fatal error: string: No such file or directory
