Hi,

Based on your error message the CHIP_ROOT variable is set to an incorrect value. This is because the method that is used to set it is not supported in Windows. You can fix this error by changing the following in CMakeLists.txt:

get_filename_component(CHIP_ROOT ${CMAKE_CURRENT_SOURCE_DIR}/third_party/connectedhomeip REALPATH)

to this:

get_filename_component(CHIP_ROOT ${CMAKE_CURRENT_SOURCE_DIR}/../../.. REALPATH)

Best regards,

Marte

Hi，Marte,

1: I have successfully build the matter project :door lock (NCS) ;

2: I still want my development to be based on the link https://github.com/project-chip/connectedhomeip/tree/master/examples/lock-app/nrfconnect

...

$ source E:/matter/ncs/ncs200/v2.0.0/zephyr/zephyr-env.sh
$ export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
$ export GNUARMEMB_TOOLCHAIN_PATH=E:/matter/ncs/ncs200/toolchains/v2.0.0/

...

i'm not sure I can do it on windows.

Best regards,

Hi,

Please install the nRF Connect SDK and build the Matter: Door lock sample there instead. This sample is located in ncs/nrf/samples/matter/lock. It is the same example as the one you are linking to, but with the library files already generated in the SDK so you do not have to build the stack and platform modules yourself. Therefore, building the sample in nRF Connect SDK is already supported on Windows and should work out of the box.

Best regards,

Marte

hi，Marte：

Yes,I can build matter projects(NCS) in windows as well.

but I can't build the project https://github.com/project-chip/connectedhomeip/tree/master/examples/lock-app/nrfconnect

I wonder if I can build in windows platform.

best regards,

Hi,

You can build Matter projects in Windows as well.

The documentation in your picture is for building Matter's stack and platform modules, which are used to generate the Matter library files. These are already built as part of the nRF Connect SDK, and the Matter library files are automatically imported when you build the application.

For how to build the Matter Door Lock sample please see Building and running in the documentation for the sample.

Best regards,

Marte
