Depmod could not open directory

Thanks dominik.tx for your answer and max.tx for your help.

I forgot to do:

make -j3 modules
sudo -E make INSTALL_MOD_PATH="path-for-modules" modules_install
cd "path-for-modules"
tar cjvf kernel-modules.tar.bz2 lib/modules/*

copy kernel-modules.tar.bz2 to target in directory “path-for-file” then :

cd /
tar xjvf "path-for-file"/kernel-modules.tar.bz2
depmod
