NCS 2.5.0: CMake Error ... version.cmake:74 (math): math cannot parse the expression

[Marko W]

After updating the NCS from 2.4.2 to 2.5.0 my project cannot be created.

The following error occurs:

-- CMake version: 3.20.5

How can I fix this?

Does this happen with only one application or are you able to reproduce the error on other samples?

I have the very same error for my project. The code compile and works correctly with SDK 2.4.2 and throw this error in 2.5.0. I get the same error for all the 3 different sample projects i tried compiling for both my custom board (nrf5340 based) and nrf5340DK

[JONATHAN LL]

Can you give me a list of what samples you have tested.

Regards,
Jonathan

Hi Jonathan,

i'm not able to recall all the samples tested because a lot of experiments, but i spent a bit of time to prepare something you can test on:

Here the samples/configurations i tested:

- "hello world" for both nrf5340dk_cpuapp and nrf5340dk_cpuapp_ns target --> ERROR on version.cmake (the same Marko W made the post for)

- "peripheral_hr" for both nrf5340dk_cpuapp and nrf5340dk_cpuapp_ns target --> WORKING

Toolchain: 2.5.0

SDK: 2.5.0

I hope this helps,

Frax

[JONATHAN LL]

Thanks Frax, will test and report interlay.

Hi Jonathan,

any news about this issue? I read the posts following this one, but i am not able to come out of this error, even with the last 2.5.2 (2.4.2 working).

I tried to fix this error adding the VERSION file (filled as docs says) to the same folder of prj.conf together with #include <app_version.h> but absolutely nothing changed.

[JONATHAN LL]

did you add the spaces like Marko W did ?

I am not able to replicate the issue as you describe here in this post. 

Regards,
Jonathan

Hi JONATHAN LL 

i would like to add these spaces, but i'm note sure to have detected the file where i need to do it. Can you provide me a specific path to check? All the VERSION files i found already have spaces before and after "="
