Hello everyone. I'm new to ROS2 galactic and I've got few problems with installation on my PC Windows 10. I'm following this guide: https://docs.ros.org/en/galactic/Inst... to install ROS2 Galactic. Before I explain my main problem with Qt please let me ask some questions to assure I did everything before correctly as I'm complete beginner:

  1. First problem I had with ROS2 installation was at "DOWNLOADING ROS2" it's not specified what to do with 'ros2-package-windows-debug-AMD64.zip' where to unpack it, for now it is in the same folder as ros2-package-windows-AMD64.zip (both unpacked)

  2. When trying to call C:\dev\ros2\local_setup.bat it shows error:

    "[rti_connext_dds_cmake_module][warning] RTI Connext DDS environment script not found (\resource\scripts\rtisetenv_x64Win64VS2017.bat). RTI Connext DDS will not be available at runtime, unless you already configured PATH manually."

What worked for me was calling C:\dev\ros2\local_setup which caused this message to pop up: Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your computer. If you trust this script, use the Unblock-File cmdlet to allow the script to run without this warning message. Do you want to run C:\dev\ros2\local_setup.ps1?

but idk if it's correct solution or mistake that can cause errors later.

  1. Last thing (at least for now), when trying to run turtlesim, at point when I am supposed to write "ros2 run turtlesim turtlesim_node" in powershell I get error: qt.qpa.plugin: Could not find the Qt platform plugin "windows" in "B:\Qt\5.15.0\msvc2019_64\plugins\platforms" This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

I tried reinstalling Qt on disk C:\ where everything else is installed, but that didn't help, neither did installing newer versions. I currently have Qt 5.15.0 installed same as it says in the guide.

What can be the cause of those problems? I am probably missing something very simple or doing something really wrong, tried looking for answers on the internet but with my limited knowledge I couldn't solve these problems.
