MLP and PlatformIO errors

[Joe]

Hi,
how can I use MLP ino code in PlatformIO? Just tried to compile example RequestSingleParameter.ino. Library is installed correctly but I'm getting these errors

Maybe someone else already solved the problems

Hi, where did that example come from?

Cheers

Hi Phil,
this example comes from your GitHub repository

Any ideas?

[Joe]

Did anybody made the CommandHandler working with PlatformIO?

[philr]

Weird, it builds fine using the arduino IDE. did you have any luck with platform IO? I dont have any experience with that one.

[strud]

I think that one of the significant differences with PlaformIO and the Arduino IDE is the requirement for forward declarations in PlatformIO or pretty much anywhere outside the Arduino IDE.

So those errors look like the command handler functions are just out of scope. Forward declarations should resolve that.
