Hello, I am trying to build sample application on for mimxrt1064_evk on windows 10. I seem to have installed everything, but i still get this error: C:\Users\mbajaj\zephyrproject\zephyr>west build -p auto -b mimxrt1064_evk samples/hello_world [1/130] Generating include/generated/kobj-types-enum.h, include/generated/otype-to-str.h, include/generated/otype-to-size.h FAILED: zephyr/include/generated/kobj-types-enum.h zephyr/include/generated/otype-to-str.h zephyr/include/generated/otype-to-size.h cmd.exe /C "cd /D C:\Users\mbajaj\zephyrproject\zephyr\build\zephyr && C:\Python36\python.exe C:/Users/mbajaj/zephyrproject/zephyr/scripts/gen_kobject_list.py --kobj-types-output C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/include/generated/kobj-types-enum.h --kobj-otype-output C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/include/generated/otype-to-str.h --kobj-size-output C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/include/generated/otype-to-size.h --include C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/misc/generated/struct_tags.json " Traceback (most recent call last): File "C:/Users/mbajaj/zephyrproject/zephyr/scripts/gen_kobject_list.py", line 62, in import elftools ModuleNotFoundError: No module named 'elftools' [2/130] Generating include/generated/driver-validation.h FAILED: zephyr/include/generated/driver-validation.h cmd.exe /C "cd /D C:\Users\mbajaj\zephyrproject\zephyr\build\zephyr && C:\Python36\python.exe C:/Users/mbajaj/zephyrproject/zephyr/scripts/gen_kobject_list.py --validation-output C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/include/generated/driver-validation.h --include C:/Users/mbajaj/zephyrproject/zephyr/build/zephyr/misc/generated/struct_tags.json " Traceback (most recent call last): File "C:/Users/mbajaj/zephyrproject/zephyr/scripts/gen_kobject_list.py", line 62, in import elftools ModuleNotFoundError: No module named 'elftools' ninja: build stopped: subcommand failed.

You need to pip3 install pyelftools or, even better, pip3 install zephyr/scripts/requirements.txt

Reopening since I missed some of the input

I tried this locally and works fine on a Windows 10 machine. It might be that you have multiple Python 3 installations and CMake is picking one where you don't have pyelftools installed.
