I can tell you how to do the make world here, but you have to understand that sometimes parts of the tree on dependent on other parts already being at a particular level. Most of such things are put in a special 'tools' list, so they get built and installed first, but there are the occaisonal mistakes. What I am trying to get at is, if you are a complete newbie to the C language, compiling, linking, and using make, well, you probably don't want to try this. You could get yourself in a bad situation, even disabling parts of your OS. Doing the make worlds is for folks willing to take the responsibility for a certain possibility of disaster. That's not to say it's likely, nor are you without help. the FreeBSD-current list helps folks doing make worlds of current sources, and you can get help here on doing builds of other versions. I just want you to be aware, you're taking chances if you're not confident of your hacking skills. That past, I'll explain the way I do it. The sources are in /usr/src, so I cd into that. I usually do this in single user make (after I do a 'shutdown now' and am in a root shell). This isn't necessary, but it makes me feel more comfortable about possibly using utils that are going to be changing. Then I just issue the command: make world -DNOSECURE -DNOPROFILE The reason I include the -DNOSECURE is because I have a dinky little two machine network, and I don't need the added security of kerberos. The reason I put in the -DNOPROFILE is because I don't normally play around with profiled libraries, and this saves a lot of disk space. You don't need to put in either of the -D flags yourself, but you had better know how to use kernberos _before_ you do a make world with it enabled: you could very easily find yourself locked out of your own machine. OK, the make world will run a long time. On my 486-66 it takes maybe 10-12 hours. When it is finished, everything in your OS _excepting_ your kernel is new. AT this point I normally make a new kernel, install it, and do a reboot.
