[SOLVED] How to add modules to build with the kernel?

Question

Hello i´m trying to learn how to build my own custom kernel and doing it the arch way https://wiki.archlinux.org/index.php/Ke … raditional. But unfortunately dm-crypt was not included in the kernel so it all failed.
svart_alg% sudo mkinitcpio -k 3.15.6 -c /etc/mkinitcpio.conf -g /boot/initramfs-test.img
==> Starting build: 3.15.6
-> Running build hook: [base]
-> Running build hook: [udev]
-> Running build hook: [autodetect]
-> Running build hook: [modconf]
-> Running build hook: [lvm2]
==> ERROR: module not found: ‘dm-snapshot’
-> Running build hook: [encrypt]
==> ERROR: module not found: ‘dm-crypt’
-> Running build hook: [block]
-> Running build hook: [filesystems]
-> Running build hook: [keyboard]
-> Running build hook: [fsck]
==> WARNING: No modules were added to the image. This is probably not what you want.
==> Creating gzip initcpio image: /boot/initramfs-test.img
==> WARNING: errors were encountered during the build. The image may not be complete.
I have never don any of this before and have no idea of how to add a missing module to the kernel i´m building. So i search on internet and had a very hard time finding a good guide for this but i fond one possible solution. https://www.kernel.org/doc/Documentatio … odules.txt
svart_alg% make -C /home/nigro_alko/Kernel/linux-3.15.6 M=/home/nigro_alko/Kernel/cryptsetup-1.6.5/Makefile.in
make: Entering directory ‘/home/nigro_alko/Kernel/linux-3.15.6‘
mkdir: cannot create directory ‘/home/nigro_alko/Kernel/cryptsetup-1.6.5/Makefile.in’: Not a directory

make: *** [_module_/home/nigro_alko/Kernel/cryptsetup-1.6.5/Makefile.in] Error 2
make: Leaving directory ‘/home/nigro_alko/Kernel/linux-3.15.6‘
So is there any one that have time to help a lost little newbie i would bee very happy  :-)

Reason enough IMO. But anyway... you refer to the Traditional build method in the wiki, but is it possible you didn't really read it? Or maybe you only skimmed it? Did you run make menuconfig? Did you try to build everything in instead of using modules? That mkinitcpio output suggests that you did.
As suggested there for first-timers, it's a good idea to start with a kernel configuration that is known to work - the Arch config is the obvious choice, but there are other sources e.g. http://kernel-seeds.org/ .
