| |
(i originally posted this to the "make" mailing list, but i figured someone here *must* have done this before.)
is there an easy way to configure/build one or both of a 2.4 and 2.6 kernel in a totally separate directory from the source directory itself?
i'd like to have a totally pristine ("make mrproper"ed) source tree, write-protected, readable by all, so that several developers can independently configure and build their own kernels without stepping on each other. currently, they all check out their own copy of the source via CVS, which starts to take up a lot of space.
obviously, it would be great if they could all set up some kind of build structure where they could do their own configuration and build in their personal work directories, so that *all* generated results (header files, object files, etc.) are placed in their work directory -- nothing should be generated in the kernel source tree itself.
i'm suspecting that, if there are solutions, they will be different from 2.4 to 2.6, so i'll take whatever solutions i can get. others have suggested using gnu make in combination with "VPATH", but i'm not sure that's going to work, as VPATH deals strictly with pre-requisites in other directories, not executable programs like scripts.

p.s. it gets more exciting since developers might want to create a downloadable image combination of a kernel and root filesystem, so they might want to have independent copies of arch/<arch>/boot/images/ramdisk.image.gz, but i'll fight with that when the time comes. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
