I am evaluating PlatformIO for my next Arduino Due project.
My greatest concern is that I want to use the latest stable version of gccarmnoneeabi (Version 8-2018-q4-major). There is of course no such release from the Arduino team, because it would force several library owners out in the world to update their libraries. Therefore the official toolchain is by far outdated.
Can you please explain how could I define my own toolchain package without overwriting the official one and use it in parallel? Is it also possible to share such a package with other users?
Wow, thank you for the recent update, updating gccarmnoneeabi to 2017-q4!
(I have just received it in the 4.0 Beta, as Atmel SAM 3.7.0.)
This seems to be a huge but reasonable step, as Arduino itself brought out this version for SAMD as a beta a while ago, so library owners had some time to adapt. This already allows us to use most of the modern C++ features.
Just for safety reasons you should also build_unflags = -std=... whatever C++ standard it was using before. Best to get a look at a compile command using pio run -v and inspecting all set -std switches for a g++ invoke
