How to add custom_target on NCS2.8.0

[loquat]

I work on NCS 2.8.0

I add follow to CMakeLists.txt

add_custom_target(

    my_release_file

    echo AAAA BBBB CCCC

    DEPENDS all

)

when run "west build -b nrf54l15dk/nrf54l15/cpuapp -t my_release_file"

error occured.

Itry it on NCS 2.6.0, it's success.

How to add custom_target on NCS2.8.0?

[Susheel Nuguru]

I think the cmake has changed in 2.8.0, try not use Depends all and instead of echo use command to start with something like below

add_custom_target(
    my_release_file ALL
    COMMAND echo "AAAA BBBB CCCC"
    COMMENT "Generating custom release file"
    DEPENDS zephyr_elf # Replace with an actual target if necessary
)

I try it. (Add to the end of CMakeLists.txt. replace zephyr_elf to exist file)

And run "west build -b nrf54l15dk/nrf54l15/cpuapp -t my_release_file"

result is
-- west build: running target my_release_file
ninja: error: unknown target 'my_release_file'

What am I doing wrong?

[Susheel Nuguru]

I have put the suggestion in ncs\v2.6.1\zephyr\samples\basic\blinky\CMakeLists.txt

And running the command west gives proper execution like below

See in the end you have your custom comment out

Not sure how you are running your west, Did you have all the environment variables set correctly in your command line terminal? How are you doing that?

Will it work with NCS 2.8.0?

[Susheel Nuguru]

I tested it for NCSv2.6.0 since you were using that
