Build doesnt work due to limitation of CMAKE_OBJECT_PATH_MAX

[APurohit10]

cbuild doesnt work due to limitation of CMAKE_OBJECT_PATH_MAX. This happened twice, first i tried FXLS8974CF interrupt example from my downloads folder and i got same issue. I created folder on desktop and ran from there, the build worked fine. But now motion_wakeup example build doesn't work due to same limitation. Please see build log for motion_wakeup example.

This is raised in the mentioned ticket as you have pointed out: explain how to increase the path limit, explain impact of using long names and give guidelines.

A short-term solution is to copy the repo into a directory root with a shorter name. For example "C:/Temp/Sensor" instead of "C:/Users/nxa11926/Desktop/NXP_Sensor_SDK-main". This will be probably already enough.

[APurohit10]

Understood but not sure whether that will help in long run (also see comment from brondani on mentioned ticket), lets keep this open as we would like to see this issue resolved before we deploy the solution.

I also am now getting these warnings and it may be result of the folder structure.
I have the c:/GIT/NPX_Sensor_SDK
So very close to directory root.
However, we introduce the very nested folder within examples. CMake warning notes below is 189 characters:
C:/GIT/NXP_Sensor_SDK/examples/issdk/sensors/fxls8974cf/interrupt/tmp/fxls8974cf_interrupt/lpcxpresso54114_a8974/release/CMakeFiles/fxls8974cf_interrupt.release+lpcxpresso54114_a8974.dir/./
The tmp folder generates length based on project name, clayer combo, release, then repeats again under CMakeFiles...

I moved my project to the same folder as Amit under desktop. My project build error changed and was identical to Amit's.
So path length is definitely affecting build results.
Do you use a Windows laptop or a Linux system? We just want to know if that is o e way to avoid path restrictions and build warnings.

[RobertRostohar]

I'm using Windows and a very short root name.
We could also consider moving the examples higher in the directory structure.

[RobertRostohar]

The path is now slightly shorter since the csolution YML files are now one level-up (develop branch).
Nevertheless, I would suggest closing this ticket, since the path limitation is a tool limitation and should be solved within the tool.

We can mark this issue as dependent on Open-CMSIS-Pack/devtools#671 issue.
