I am following the official tutorial to install ROS2 on Windows. At the step of Environment setup, I did "> call C:\dev\ros2_galactic\local_setup.bat"

and here comes the 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."

Please advice. Thank you.

Same for me actually. Let's hope that someone has some workaround to it!

You should be able to ignore the warning.

In the official installation instructions, it says: "It is normal that [running local_setup.bat], if nothing else went wrong, outputs 'The system cannot find the path specified.' exactly once." I believe that it refers to the same warning, although the exact phrasing of the warning has apparently changed after the instructions were last updated.

See also a ROS tutorial, which says: "If you get an RTI Connext DDS environment script not found warning, you can safely ignore it in the scope of this tutorial."

I considered this a possibility, however the reason I'm at this page is because I followed the Windows Installation Instructions, the Environment Setup step prints the warning mentioned above, and when I try to run the examples immediately following, it just prints "failed to create process."

I encountered the same problem yesterday and have solved it. In my opinion, you might need to install the Eclipse Cyclone DDS manually (see After the installation it should be fine (though the error message won't disappear).
