Cmake Error "Math cannot parse the expression" with NCS > 2.4.2

[frax84]

Hello,

i'm using nrf connect sdk 2.4.2 to develop the firmware for my custom nrf5340 board without issues. I'm trying to upgrade to the the latest release but both 2.5.0 and 2.5.2 gives me this error when trying to compile:

CMake Error at D:/Nordic/v2.5.0/zephyr/cmake/modules/version.cmake:74 (math):
math cannot parse the expression: "( << 16) + ( << 8) + ()": syntax error,
unexpected exp_SHIFTLEFT (4).

I found THIS issue on DevZone that is extremely similar to my one and posted there some material to test on, but i didn't get any feedback in few months. For this reason, i'm opening a new issue.

The issue is clearly correlated to the Application versioning, but even reading the docs and making some tests i was not able to solve it.

Any suggestion?

I'm a bit at a loss here. Could you upload your project so I can have a look?

Just to summarize 

New version of the SDK

new sample project with only hello world and no changes? Are you including any file named version in your project folder? I don't believe are you, just need to check. 

Could you generate the support information from vscode and post it here?

Regards

Runar

NB: Due to public holidays here in Norway, we will be out until the 2. of April.

Hi runsiv,

Correct, new version of SDK and toolchain. Project with only hellow world and no changes. I am NOT including any file named version in my project folder. 

Here follows the support information generated from vscode:

Thanks for confirming. This means the SDK should be correctly installed. From the same terminal you ran 'west update' in, please run

west forall -c "git reset --hard"

for good measure. Note: this will revert any local changes in your SDK tree.

Then, in C:/ncs/v2.6.0/zephyr/cmake/modules/version.cmake b/cmake/modules/version.cmake, add the following line to print the VERSION files used in the build:

diff --git a/cmake/modules/version.cmake b/cmake/modules/version.cmake
index 4c80c5fcdc..46c430f5a7 100644
--- a/cmake/modules/version.cmake
+++ b/cmake/modules/version.cmake
@@ -43,6 +43,7 @@ if(NOT DEFINED VERSION_FILE AND NOT DEFINED VERSION_TYPE)
 endif()
 
 foreach(type file IN ZIP_LISTS VERSION_TYPE VERSION_FILE)
+  message(ERROR ${VERSION_FILE})
   if(NOT EXISTS ${file})
     break()
   endif()

After this, build one of the SDK samples that will fail and post the build log from terminal here.

E.g., 

/zephyr/samples/hello_world$ west build -b nrf5340dk_nrf5340_cpuapp -p

[frax84]

Ok. This is what i've done:

1) west forall -c "git reset --hard" ---> No errors arose

2) in "C:/ncs/v2.6.0/zephyr/cmake/modules/version.cmake" i added the line "message(ERROR ${VERSION_FILE})" just after the "foreach" line.

3) in the "Nrf Connect" tab of VS code i selected the hello_world build config and in "Actions" i clicked on "Pristine Build"

This is the output: (for some reason i can't "insert code")

Hi,
Just started to take a look.
I wonder why there is a double `VERSION/VERSION` here:

-- west build: generating a build system
ERRORC:/ncs/v2.6.0/zephyr/VERSION/VERSION

This indicates to me that the problem might be related to `VERSION` somehow being appended twice to that setting and therefore not found during build, which again causes values for the match operation to be empty and therefore fail.

It would be a big help if you can provide a CMake trace file for further investigation as to what exactly happens.
Run the `west build ...` command as printed in your last comment and then add:

-- --trace-expand 2> cmake.trace

and attach the cmake.trace file to this thread.

[Torsten Rasmussen]

Reason for the `/VERSION/VERSION` printing is found.
It happens because the VERSION_FILE variable is a CMake lists of two elements, which in CMake is separated by a `;`.

But when you're printed the message, that list is concatenated into a single string, and the `;` disappears in that process, so this part actually looks correct.

But a cmake.trace file is still valuable for further investigations.
