Raspberry Pi3B+ install newly-released ROS2, failed in build and run

edit

The instruction I followed was: https://index.ros.org/doc/ros2/Instal...

I ran:

colcon build \
   --symlink-install \
   --cmake-force-configure \
   --cmake-args \
     --no-warn-unused-cli \
     -DCMAKE_TOOLCHAIN_FILE=`pwd`/aarch64_toolchainfile.cmake \
     -DTHIRDPARTY=ON \
     -DBUILD_TESTING:BOOL=OFF \
     -DCMAKE_BUILD_RPATH="`pwd`/build/poco_vendor/poco_external_project_install/lib/;`pwd`/build/libyaml_vendor/libyaml_install/lib/"

and got:

Failed   <<< qt_gui_cpp [ Exited with code 1 ]
Aborted  <<< ros2node
Aborted  <<< rosidl_typesupport_fastrtps_c
Aborted  <<< rosidl_typesupport_introspection_cpp

  5 packages had stderr output: console_bridge_vendor libyaml_vendor qt_gui_cpp ta_security_api uncrustify_vendor

then I ran:

~/ros2_ws/install/local_setup.bash

but got:

not found: "/home/yc/ros2_ws/install/ta_security_api/share/ta_security_api/local_setup.sh"
not found: "/home/yc/ros2_ws/install/ta_security_api/share/ta_security_api/local_setup.bash"

not found: "/home/yc/ros2_ws/install/ca_security_api/share/ca_security_api/local_setup.bash"

finally I ran:

ros2 run demo_nodes_cpp talker

and got:

How can I solve these problems?
