build doesn't recognize zephyr files

[Raz_k]

Hello,

im trying to do the first exercise in DevAcademy (https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/lessons/lesson-2-bluetooth-le-advertising/topic/advertising-process/) and i downloaded the relevent git aip file and opened a new project. its path is: C:\nordic\BLEexample\bt-fund\lesson1\blefund_less1_exer1

and my zephyr files are in : C:\ncs\v1.9.0\zephyr\include\sys\printk.h

the CMakeLists.txt are are as downloaded:

#

and i the build fails:

any idea why?

Hello,

That is odd. Are you able to simply build a default sample from the SDK?

Regards,

Elfving

[Raz_k]

Hey Elfving,

Yes i am able to build and flash an example of BME sample sensor, that is located in C:\bme680

and its CMakeList.txt is:

#

# Copyright (c) 2018 Bosch Sensortec GmbH

#

# SPDX-License-Identifier: Apache-2.0

#

cmake_minimum_required(VERSION 3.20.0)

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})

project(bme680)

FILE(GLOB app_sources src/*.c)

target_sources(app PRIVATE ${app_sources})

 

i tried to include the same librarys that where unable to include and build in the original issue file:

#include <zephyr/sys/printk.h>

#include <zephyr/sys/byteorder.h>

#include <zephyr/kernel.h>

#include <zephyr/drivers/gpio.h>

#include <soc.h>

#include <zephyr/bluetooth/bluetooth.h>

#include <zephyr/bluetooth/hci.h>

#include <zephyr/bluetooth/conn.h>

#include <zephyr/bluetooth/uuid.h>

#include <zephyr/bluetooth/gatt.h>

but i get the same errors as i mentioned before.

Hello again,

Ah yes. I see that you are running it in NCS version 1.9. I think the newer versions are the ones that are tested/supported with this course. Try NCS NCS 2.4.0 and above. There are a few changes made inbetween these NCS versions, and 1.9 is starting to get old. If you have a larger ongoing project I would understand if you stick to one NCS version for a longer period of time, but for learning NCS and BLE I would recommend upgrading to the latest NCS versions. 

When it comes to the issue itself, it seems that you need to write #include </sys/printk.h> in NCS1.9, not #include <zephyr/sys/printk.h>. But nevermind that, just install a newer version.

Regards,

Elfving

i removed NCS version 1.9. I and installed the newer version 2.5.2.

and still im unable to build:

 plus i tried in 1.9.1 version to remove the /zephyr/ path in the include, but it didnt help.

[Elfving]

Could you try placing BLEexample/bt-fund/ in /ncs/, maybe there is something strange going on with the west workspace.

What HW are you building the sample for?

Could you check and make sure that you are using a corresponding newer toolchain?

Elfving
