How to compile specific kernel directory

Postby araneus » 2015-11-09 11:30

As the title says, is there a way to compile specific directory (not a module, just the directory)?
Takes so many hours to compile whole kernel with my old computer, so it would be nice to do check compiles every now and then for the changed directories only.

Lets say I modify files in drivers/tty/vt/ directory and want to do a test compile for this directory only.
Is that possible? Or do I have to compile the whole kernel once first and after that I can compile specific directories again after modifying them?

These do not work in this case:
cd drivers/tty/vt && make
make -C drivers/tty/vt

I am using Debian Jessie (686) with packages: kernel-package linux-source-3.16

Thanks.

I don't know if this will help you, it might

Before doing anything, read the Debian documentation:
