Mavsdk: Build a Raspberry companion for PX4 to use MAVSDK

[helloE9]

Hi,
Why I still have this problem on Rasbian OS on Raspbery Pi 3?

pi@raspberrypi:/MAVSDK $ sudo cmake --build build/default

//
is there I should clone the correct release for Raspberry Pi?

First, cmake does not need sudo. So this is most likely wrong: sudo cmake --build build/default.

Can you show the command line you use for the configure step? Is that a clean build?

It looks like your compiler and standard library are too old and don't support features (like std::optional) used in MAVSDK.
What RPi OS image are you using? You probably have to update to something newer.

yes. after got some error several times, I just thought to try with 'sudo' if there was any permission problem.

I did follow steps listed on build guide from MADSDK github

sudo apt-get update -y
sudo apt-get install cmake build-essential colordiff git doxygen -y

Clone the MAVSDK repository (or your fork):
git clone https://github.com/mavlink/MAVSDK.git
cd MAVSDK
git checkout develop
git submodule update --init --recursive

cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -Bbuild/default -H.
cmake --build build/default
->>> at this phase I've got some errors

and, as julianoes has mentioned bellow, I forgot I installed old gcc to test very old module :(
so, now I did upgrade gcc to 8.3 and doing build again.

Thanks!!! and, I forgot I installed old gcc to test very old module :(

for some case, I am making another sd-card to install Raspbian burst 10 and gcc 9.1.

Nice, so the issue can be closed?
