[gentoo-user] Changing CFLAGS
Hi there! My motherboard or CPU just died, I am using a replacement system for a while. It's an Athlox-XP, while I had an AMD-64 before. I did not use 64 bit mode, but I have -march=k8 in my CFLAGS, and get lots of illegal instructions. Seems I need to re-compile everything with different CFLAGS, maybe -mcpu=k8 maybe this time as I am planning to re-activate the old system some time. What would be the best way to do this? I thought about unpacking a stage1 tarball, changing CFLAGS, calling bootstrap.sh and doing an emerge -e world, but this would overwrite things in /etc and clutter my file system with more things I do not really want, like creating entries in /dev. I would rather like to keep the current setup as it is. I think that I saw a howto once about what to do in such a case, but at that time I did not need it, and now I cannot find it. BTW: What exactly are the benefits from using march instead of mcpu? Is there a noticeable difference in speed anyway? With mcpu I would not have the trouble I am having now...

I would rather like to keep the current setup as it is. use knoppix. If you don't want to reinstall everything and the XP is just a temporary replacement, get a knoppix livecd. It lets you save things to a file, if you want to.

Your trouble started, when you switched to a completly different cpu... mcpu = only rearranging stuff so it might run better on the cpu specified. No instructions and features used, that are not available on all the other cpus from a family (in theory, a binary built with mcpu=athlon-xp should be able to run on a i486). march = optimizing for the specified cpu. Using all features and instructions available, building stuff not able to run on other cpus. (so a resulting binary of march=athlon-xp won't run on a i486) usually march is faster on the given cpu, mcpu is more compatible. -- [EMAIL PROTECTED] mailing list
[gentoo-user] Changing CFLAGS and cloning the system.. What are my options?
Hi folks, Please bear with me, even if this seems a little newbie-sh. I have a perfectly running Gentoo AMD64 system, with XGL and all. Now I've figured that I need to change my CFLAGS. It's some stupidity on my part, please don't ask. So I guess I'll need to rebuild my entire system. Anyway, I have about 11GB free on the hard disk. I am thinking about building binaries of all the installed packages on the system, keep them burnt on a DVD. I'll back up my /etc. All my data partitions and /home are on different partitions, so I don't see any need to back them up. Also, I'll keep the 2006.0 minimal install CD handy. It does support LVM right? What do I do with the stage tarballs? How can I make a snapshot of this working system as a fallback? I remember something about a Stage 4 in the forums a while ago.. I installed this system well over a year ago with a Stage 1 tarball. Should I keep Stage 3 handy? Is there anything else I should be worried about? Have I forgotten something in case something goes wrong and I have to reinstall the entire thing... Another thing, I'll need to make an exact copy of this system, once rebuilt, on a friend's laptop, albeit with a different partition setup. My system has LVM setup, the laptop won't have that. What all needs to be changed? Sorry to ask so many question, I'm just worried about messing up the fine system.. :/ Thanks and regards, Mrugesh pgpCvdOKEFA21.pgp Description: PGP signature
