An error occurred while compiling the "channel_sounding_ras" process：，A certain file is missing. I am using version 3.0.2 of ncs.Could you please tell me how to solve this problem?

Hello,

This is probably because the path is too long. I guess that if you look a little longer up in the build log, you will see something like this:

This usually (but not always) results in a file not being found (but may also result in other types of errors).

So the easy workaround is to move the sample folder closer to your C-drive, giving it a shorter path. E.g. create a folder called C:\ncs\my_apps\3.0.2\, and place the channel_sounding_ras_initiator sample there. Also, rename it to something shorter, like cs_init, and cs_refl. (these channel sounding samples are particularly voulnerable to this "long path" issue).

Alternatively, if you are building using the command line, you can build using ninja directly, instead of using the "west build" command. For that, please use these commands:

cd channel_sounding_ras_initiator
mkdir build
cd build
cmake .. -DBOARD=nrf54l15dk/nrf54l15/cpuapp -GNinja
ninja

But if you are using VS Code, then make the sample location have a shorter path.

Best regards,

Edvin
