hello_dect sample can't be built using cmake

[kirill.neznamov]

Hi. I can't build the hello_dect example using cmake, the build process is failed with the following error:

In file included from /home/cybermag/ncs/nrf/modules/trusted-firmware-m/tfm_boards/partition/region_defs.h:10,
                 from /home/cybermag/ncs/modules/tee/tf-m/trusted-firmware-m/platform/ext/common/gcc/tfm_common_s.ld:25:
/home/cybermag/ncs/nrf/modules/trusted-firmware-m/tfm_boards/partition/flash_layout.h:10:10: fatal error: pm_config.h: No such file or directory
   10 | #include <pm_config.h>
      |          ^~~~~~~~~~~~~
compilation terminated.


Steps which lead to that behavior:
1. go to nrf/samples/dect/dect_phy/hello_dect
2. Add  set(BOARD "nrf9151dk/nrf9151/ns") to CMakeLists.txt (I want to build non secure firmware)
3. cmake -S . -B build
4. cmake --build build

can you give me some advice how to fix it?

BTW, I can build the sample using west:
west build -b nrf9151dk_nrf9151 -p always -- -DEXTRA_CONF_FILE=overlay-eu.conf -DBOARD=nrf9151dk/nrf9151/ns

but I need working cmake for my project.

FYI: Version of nrf sdk is 2.9.99.

Hi,

 

Try this, and please share the full output if it still fails:

mkdir build
cd build
cmake .. -DBOARD=nrf9151dk/nrf9151/ns -DEXTRA_CONF_FILE=your-added-conf-file -GNinja
ninja

I recommend that you try on a tagged version of ncs, for instance v2.9.1.

 

Kind regards,

Unfortunetly I have to use sdk from main branch.
I've tried to build using your recommendations but the build still fails.
Here are the output:

Hi,

 

I get the same if I use cmake directly on main:

This is the same error message that is emitted if you use west with nosysbuild:

west build -b nrf9151dk/nrf9151/ns -d build  --no-sysbuild

I would suggest that you use west for the moment, given that you are already using the tip of main,

 

Kind regards,

Håkon
