[Foxy] colcon build returns PermissionError WinError5 when trying to build any package.

[VinHub-Gitcent]

I am experiencing problems with colcon build. I am running it in x64 Native Tools Command Prompt for VS 2019 as admin. I get this error for every colcon build i was trying to create.

I am using ROS2 foxy for Windows. View the full Error Message below:

Failed   <<< turtlesim [0.16s, exited with code 1]

Summary: 0 packages finished [0.42s]
  1 package failed: turtlesim
  1 package had stderr output: turtlesim

This is a really basic operation and should run out of the box when following the installation guide from:
https://ms-iot.github.io/ROSOnWindows/GettingStarted/SetupRos2.html

Does Anyone has an idea why this error occures?

[ooeygui]

Hi there,
I have not seen this specific issue before. I suspect that this may be blocked by a virus scanner?

[VinHub-Gitcent]

Hi thank you for your reply. I think the virus scanner is not interfering here.
I wonder if the Warning:
WARNING The path 'C:\opt\ros\foxy\x64\tools\vcpkg\installed\x64-windows' in the environment variable CMAKE_PREFIX_PATH doesn't exist should occur here.
This is what I got from the colcon log file, maybe this helps.

What are your thoughts on this?

Thanks for the log. The warning is a red-herring. We preemptively put that in the path, in case a rosdep needs to use vcpkg. If you create that directory, the warning will go away. (We should have done that in setup, but it was broken at some point)

This line is suspect C:\Program Files\CMake\bin C:\dev\ros2_ws\src\ros_tutorials\turtlesim -DCMAKE_INSTALL_PREFIX=C:\dev\ros2_ws\install -G Visual Studio 16 2019

It looks like it is missing cmake.exe - it should be:
`C:\Program Files\CMake\bin\cmake.exe C:\dev\ros2_ws\src\ros_tutorials\turtlesim -DCMAKE_INSTALL_PREFIX=C:\dev\ros2_ws\install -G Visual Studio 16 2019

I won't ask you to post the environment as it includes sensitive info.
However, I would have expected it to use the one deployed in c:\opt\ros\foxy\x64\cmake.exe.
Perhaps you have an environment overriding it?

Thanks for your reply.
I had an existing installation of CMAKE on my system. After uninstalling it and removing from PATH the colcon command works as intended.
I still don't get why using another functional installation of Cmake crashes colcon, but the issue can be considered closed I think.

I wonder how I can have a second version of Cmake installed without it interfering with the colcon command of foxy. Maybe you can give me some idea for that.

Thanks again and best regards.

Thank you for closing the loop. I suspect that between versions of cmake the environment variable that's used to locate it changed behaviors? Or on Windows the environment variable behaves differently than on linux?

I'm glad it is working.
