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 Scanning dependencies of target gtest [ 1%] Building CXX object src/third_party/gtest/googletest/CMakeFiles/gtest.dir/src/gtest-all.cc.o [ 1%] Linking CXX shared library ../../../../lib/libgtestd.so [ 1%] Built target gtest Scanning dependencies of target mavsdk [ 2%] Building CXX object src/core/CMakeFiles/mavsdk.dir/call_every_handler.cpp.o [ 2%] Building CXX object src/core/CMakeFiles/mavsdk.dir/connection.cpp.o In file included from /MAVSDK/src/core/mavsdk_impl.h:13:0, from /MAVSDK/src/core/connection.cpp:2: /MAVSDK/src/core/safe_queue.h:5:20: fatal error: optional: No such file or directory compilation terminated. make[2]: [src/core/CMakeFiles/mavsdk.dir/build.make:76: src/core/CMakeFiles/mavsdk.dir/connection.cpp.o] Error 1 make[1]: [CMakeFiles/Makefile2:182: src/core/CMakeFiles/mavsdk.dir/all] Error 2 make: *** [Makefile:130: all] Error 2

// 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?

fatal error: optional: No such file or directory

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.

First, cmake does not need sudo. So this is most likely wrong: sudo cmake --build build/default. yes. after got some error several times, I just thought to try with 'sudo' if there was any permission problem.

Can you show the command line you use for the configure step? Is that a clean build? 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 :( so, now I did upgrade gcc to 8.3 and doing build again. 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?
