virtualbox.org

Hi guys, I am actually working on my new distro. I almost done my package manager, it build everything from scratch. Anyway.

So I just finished to follow the guide to build virtualbox. My question is now, how can I perform something like a make install with a specified DESTDIR ?

The VirtualBox build system doesn't really have a "make install" equivalent. After the "kmk all" run you should have everything necessary in the out/.../release/bin directory. You could look at how our deb/rpm package build works. Those use those files and re-arrange them into the final install layout. There are multiple possibilities (compare where e.g. .deb packages place the files to where they are in the .run installer produced by "kmk packing").
