VirtualBox

source: vbox/trunk/src/VBox/HostDrivers/Support/linux/Makefile@ 88087

Last change on this file since 88087 was 85939, checked in by vboxsync, 4 years ago

Additions/linux/Makefile, HostDrivers/linux/Makefile: Many cleanups in the Linux kernel module Makefiles, making them more uniform, and allow install of individual modules. Additionally, allow building of the kernel modules straight from the respective subdirectory (no dependencies across directories, so vboxdrv/vboxguest still needs to be built first, otherwise you end up with undefined symbols). Finally some parallelization improvements. At the top level still uses the Module.symvers copying and somewhat quirky KBUILD_EXTRA_SYMBOLS pointing to the copy, because this is backwards compatible to before KBUILD_EXTRA_SYMBOLS was invented.
