a Problem when compiling in Seeger Embedded studio

[Omar]

Hi
I made some changes in the chat project that is found in NRF Connect SDK
and when I build the change project this error occurs

kobj-types-enum.h: No such file or directory
Build failed

this is the full building output:

This may be caused by the Windows path length issue: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/known_issues.html#build-system 

Try to name the build name "build" instead of "build_nrf5340dk_nrf5340_cpuappns" or place NCS closer to "C:/" (in C:/ncs/v1.5.1/ instead of C:/Users/OMAR/ncs/v1.5.1/) to shorten the path length.

the name was build_nrf52840dk_nrf52840, i rename it to build but the same problem occurs.

Try to place NCS closer to "C:/" (place it in C:/ncs/v1.5.1/ instead of C:/Users/OMAR/ncs/v1.5.1/) to shorten the path length.

If it still doesn't work, can you please upload your project and I'll try to reproduce it on my side.

Best regards,

Hi 

I'm actually trying to create a model that sends a periodic message, so I begin modifying the chat example.

I uploaded my source code without the build folder so that you can build it correctly 

thank you 

[Simon]

Did you give me the whole project? The file model_handler.c included the file AdsumNet_Keepalive.h, which was not included in your project.

../src/model_handler.c:15:10: fatal error: AdsumNet_Keepalive.h: No such file or directory
   15 | #include "AdsumNet_Keepalive.h"

Can you upload your whole project, and all the files you've used.

I used NCS v1.5.1 by the way. Is that the version you're using?

[Omar]

I uploaded the wrong file sorry.

3513.chat2.zip

I did the following:

• Used NCS v1.5.1
• Placed project in ncs/nrf&samples/chat2
• Built it using west build -b nrf52840dk_nrf52840 -d build_52840 -p
  • Got the following error

../src/Keepalive.c:187:1: error: expected '=', ',', ';', 'asm' or '__attribute__' at end of input
  187 | a

• Removed the 'a' from the bottom of keepalive.c
• Built it again using west build -b nrf52840dk_nrf52840 -d build_52840 -p
  • Got the following errror:

../src/Keepalive.c:175:32: error: 'BT_MESH_KEEPALIVE_OP_PRIVATE_MESSAGE' undeclared (first use in this function); did you mean 'BT_MESH_KEEPALIVE_OP_MESSAGE'?
  175 |  BT_MESH_MODEL_BUF_DEFINE(buf, BT_MESH_KEEPALIVE_OP_PRIVATE_MESSAGE,
      |                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

• Then I added the following in keepalive.h to make it compile

/** Presence message opcode. */
#define BT_MESH_KEEPALIVE_OP_PRESENCE BT_MESH_MODEL_OP_3(0x0D, \
				       BT_MESH_KEEPALIVE_VENDOR_COMPANY_ID)

/** I added this below, to make it compile*/
#define BT_MESH_KEEPALIVE_OP_PRIVATE_MESSAGE BT_MESH_MODEL_OP_3(0x0D, \
				       BT_MESH_KEEPALIVE_VENDOR_COMPANY_ID)

• Built again
  • It worked!

It is strange that it didn't work for you. I built on both Windows and Linux and it built successfully. I tried with both 'build' and 'build_nrf52840dk_nrf52840', as well as 'build_nrf52840dk_nrf52840_123456789123456789' to test the Windows path length issue, but it still worked.

Can you test on a different computer? Try to uninstall and install NCS and see if it works then.
