RE: Question on order and targets of kernel and world builds
"make buildworld" -- builds the kernel and the libraries (both kernel and user level) "make buildkernel" -- builds only the kernel You can build kernels with different configuration files using "make buildkernel KERNCONF=".

Re: Question on order and targets of kernel and world builds
Title: Re: Question on order and targets of kernel and world I would appreciate a bit more information on the 'world' and 'kernel' building process. Please point me at the right section of the Handbook or Greg's book if there is a succinct description. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cutting-edge.html I have been doing 'CVSUP' followed by: # make buildworld # make installworld # make buildkernel # make installkernel without really knowing if this was a useful order or exactly what I was accomplishing with each target. My question is: 1) Can I 'make buildworld' to create my tools and supporting files, then 2) Use the newly made "world" to 'make buildkernel', and then 3) 'make installworld; make installkernel' to install these new filesets for general use? I would like to know if this is an acceptable and conservative way to do a rebuild, and to better understand what I get at each step. Here are the steps I follow. Note that I previously built a custom kernel and I am using that below. Replace "CUSTOM" with whatever you named your kernel. Please *read the handbook* as things can get confusing. Not something you want to fubar at 2 am. Mergemaster especially can be tricky until you figure out what's going on. Good luck. 1. # cd /usr/obj # chflags -R noschg * # rm -rf * 2. #make buildworld 3. #make buildkernel KERNCONF=CUSTOM 4. #make installkernel KERNCONF=CUSTOM 5. boot into single user mode 6. #make installworld 7. # cp -Rp /etc /etc.old 8. # mergemaster -cv 9. reboot -- Jim Arnold - Ohio.com - [EMAIL PROTECTED] Cell: 330.730.0797 Voice: 330.572.2822 AOL IM: instantjim / Yahoo: jim0266

You should check: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more details that you probably even need to know (because it includes information for older releases of freebsd). If you are fairly up-to-date with freebsd-stable, the preferred order would be more like: *READ* /usr/src/UPDATING [every time, just to make sure there are no special issues with this specific snapshot of freebsd] mergemaster -p make buildworld make buildkernel make installkernel [reboot, to make sure the kernel at least boots up] get into single user mode [usually by booting into it in the above step, although I often cheat on that...] make installworld mergemaster [go thru all the questions from mergemaster] reboot into your new world. You do not want to install the new world before you know whether the kernel that matches it will work on your hardware. If the kernel does *not* work (and I have had cases where this happens, although not very often on freebsd-stable), then you can easily back out by just renaming the kernel-related files in '/'. If you have done the installworld and *then* find out the new kernel does not work, well, you'll be in a world of hurt. Many people will try things in a different order, and will happen to have it work, and will thus insist that their order is the correct order (and usually "that it saves them a lot of time"). Their order may even work for six to eight months at a stretch, which they consider "proof" that it is a perfectly correct order. The documented order is the order you should stick with, because it's the only order that we actively *try* to keep working. If some other order happens to work, feel free to use it, but do not come complaining to us for the update where that alternate order does NOT happen to work... -- Garance Alistair Drosehn= [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Instituteor [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Re: Question on order and targets of kernel and world builds
Thanks Jim, Garance, and Pavan - I think I have the information and references now. I also think I had didn't have trouble before because I was basically moving only by very small steps in my rebuilds: bugfixes rather than any changes of APIs. _Much_ better to do this a bit more knowledgably. - John Mills To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Re: Question on order and targets of kernel and world builds
I'm pretty sure that that buildworld does *not* build kernels. If anybody has definitive information (like, proof) to the contrary I'd be interested in knowing.

He's either quite wrong, or he meant to say that buildworld builds "kernel source", meaning ~'files needed to build kernel' ??

RE: Question on order and targets of kernel and world builds
Nope. buildworld != builkernel. But buildworld does link the libraries. For example if you have a system call and a corresponding library, buildkernel will not be sufficient for you to allow the library call to invoke the corresponding system call -- however a buildworld would do that.
