Thank you for clarifying ! but I am trying to create a specific kernel I am don't intend to work with the default configuration, actually I am a little bit lost I need to cross compile Qt on an os which has no desktop version no server x ... it will be for an industrial project and will be implemented on raspberry pi 4 , In the beginning I tried to build a kernel following the official documentation of raspberry and it didin't work for me I couldn't mount the image raspberrypi.stackexchange.com/questions/118498/…

@DmitryGrigoryev I just read it, so I presume that the source code of this os and the Makefiles are not available on my sdcard but in the host machine where it was developed ? so doing a make menuconfig has no meaning?

I installed libncurses5-dev and still couldn't access the menuconfig I got the same error, I followed the kernel building instruction but it couldn't work for me raspberrypi.stackexchange.com/questions/118498/… so I gave up and worked with raspberry pi os lite but now I want to make my one microlinux os so I am working on buildroot

I saw that in an other question so I did the same hoping that it could help someone ! but it's okay I noted that thanks !

Thank you so much ! It worked for me ! I just spent a couple of days looking for a solution ! thank you for your help :D , I will edit my question to make it more clear it might help someone

Thank you but it is not exactly the same problem :/

okey I am sorry I am new to all of this. I will create new questions! thank you

Thank you so much for all the informations, but I was thinking of creating something like Raspberry pi os lite because it comes without a GUI but the problem is that in /boot there is 4 .img files to make it work for all the versions of raspberry pi so I just wanted to create an OS with no GUI and which is specific to the boardcom bcm2711 only. Do you think that the 3 other .img files would consume time ? or they would be activated only when running the os in another version of raspberry pi ? Do I need to remove them ? and also please if you have some tips on how to disable modules
