did you get any specific error message above in the colcon output? This output is just telling you that the package failed to build; it's almost impossible to help with that information only. This file should contain much more information: log\latest_build\iceoryx_posh\stdout_stderr.log

past the log content:log\latest_build\iceoryx_posh\stdout_stderr.log

Thanks

It seems an issue relate to language on windows. Once I added English Language support, it works now. I am not sure why only this file has such kind of issue but it works now. Appreciate any explaining if anyone have.

Thank you a lot.

Thanks for providing the output (although adding the file content to your post by editing your post and pasting the content would've made it a bit easier to read!). It looks like "error C2001" is common for Chinese-language Windows. If you google "Windows error C2001 Chinese" you'll find many results, and it looks like this is an encoding issue. I think that, by enabling English language support, you probably added the missing encoding support. Something about this is mentioned for the Ubuntu build/install instructions, but not for the Windows instructions, so I will add it. Thank you for mentioning the solution!

I am also getting this error (1 package failed iceoryx_posh) building ros2 Humble from source on Windows 10. How do I add English Language support?
