boilerplate.cmake not found because ZEPHYR_BASE isn't set

[builder01]

Hi,

I'm very confused by this error.

I have a project with the following CMakeLists.txt file

cmake_minimum_required(VERSION 3.20.0)

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(bike_finder)

target_sources(app PRIVATE src/main.c)
//... more target sources

# NORDIC SDK APP END
zephyr_library_include_directories(.)

When the project is tried to be built at the startup of VScode, I get the following error message

When I open a terminal, I ran echo $ZEPHYR_BASE, but it came out empty.
Therefore, I go into the nRF Connect SDK folder that I'm using (v2.2.0-rc1), run source zephyr/zephyr-env.sh and then the terminal finally recognizes where ZEPHYR_BASE is.

To rebuild, I just do a dummy modification to the file (use :w since I'm using vim within vscode), and then application tries to rebuild again, but I keep the same error.

If I go to the nRF Connect extension section, I see my folder under applications, but it's followed by "no build configurations", because of this problem.

What should I do?

Hi,

ZEPHYR_BASE should be set correctly if you use VS Code with the nRF Connect for VS Code extension and has selected the correct SDK and toolchain. If you go to the welcome page of the extension and Quick Setup, what is nRF Connect SDK and nRF Connect Toolchain set to?

You can also set ZEPHYR_BASE in your environment variables. The path of this should be the zephyr directory of your nRF Connect SDK installation, so for example something like /home/ernesto/ncs/v2.1.0/zephyr.

Best regards,

Marte

Quick setup

Settings in workspace

Should I replace the settings in the workspace by the absolute path?

[builder01]

dejans and even if the board didn't exist, that shouldn't be a problem, since I'm not even uploading my code to the board yet (though I did it before this problem came with no problems).

The problems come really at startup.

There must be some sort of file I should be able to show you that indicates where I'm going wrong, but I don't know which one.

[builder01]

Ok, I managed to fix the boards problem. It seems that removing the cmake extension allowed me to work through it.

However, now I'm having still one more problem, the following lines in my main.c are failing due to not being able to locate these files:

#include<zephyr.h>

#include<sys/printk.h>

Again, opening the terminal from the toolchain manager outputs the correct location for the zephyr folder:
/home/ernesto/ncs/v2.2.0-rc1/zephyr

And I have made sure that both files exist in said directory.

In the compilation command, I see the following directory included with -I (besides many others, ofc):
-I/home/ernesto/ncs/v2.2.0-rc1/zephyr/include

Now, the zephyr.h is in .../zephyr/include/zephyr

So I wonder whether the -I statement up to .../include is enough, or should it be extended up to zephyr as well? If so, how can I include that?

[dejans]

Hi,

Regarding the board name, I am sorry for the confusion. You mentioned nRF52832-DK, so it could be that you meant either nRF52-DK (which has nRF52832) or you mistyped nRF52833-DK. 

Could you send log output of the build process?

Best regards,
Dejan

I see, my bad.
This is the output log of the building process:

Hi,

Is this output log from VS Code or from the terminal which is started using Toolchain Manager?

Best regards,
Dejan

[builder01]

from VS Code after I press build on the nrf connect extension.

[dejans]

Hi,

Could you try using "west build" command from the terminal opened from Toolchain Manager?

Best regards,
Dejan

[builder01]

I just tried "west build --build-dir /home/ernesto/ncs/bike_finder/build /home/ernesto/ncs/bike_finder" from the terminal opened from the toolchain manager. I did it from /home/ernesto/ncs/bike_finder/.

Got the same errors I copied above. Yet, doing echo $ZEPHYR_BASE still outputs .../v2.2.0-rc1/zephyr, which is correct.

[dejans]

Hi,

You could try to do pristine build. If the same error appears, try removing build folder first and then do pristine build again.

Best regards,
Dejan

[builder01]

If I do pristine build from Vs code, I get the same error.
If I delete the build directory and run the west command from terminal opened from the toolchain manager, then I get the original error I mentioned previously:
