LFS hardware requirements


Hello,

I did not actually find any data about minimum hardware requirements for LFS building and running. Can anyone tell me more about it ?

Thanks for any help,

Josip

how low-end is your system that you are even worrying about it?

Thank you for your kind reply.

Well, my main system is Quad Core Q6600 but system on which I want to build LFS is old Pentium on 200 MHz with 256 MB of RAM. Honestly, I am experimenting how low with hardware configuration can I get with LFS. This system has already installed RedHat 6 as main system.

And BTW, in those days much more reliable hardware was made. Or maybe I am just hopelessly nostalgic.

Regards,

Josip

Why not? The lowest spec machine I remember ever putting LFS on was a 500MHz Athlon with 256MB RAM. It'll take you days, but I don't see any reason that machine won't work. You could build for the Pentium on your Quad Core and then move it over to save time though.

You're hopelessly nostalgic.

That is precisely what I'll do. Thanks for your advice !

Oh no!

I would suggest you take a look at CLFS, then build LFS using a cross-compiler on your main system. Then again if your libc is for i486/i586 and your gcc automatically targets i486/i586, you don't even need a cross-compiler. A 200Mhz Pentium will take HOURS to compile some of the libraries. Don't even try to build X on that machine - it can be done, but it's not a pleasant experience. Of course if you don't mind the agony and want to have a laugh at how long it takes to build X, go ahead.

I built gentoo on a 333mhz powerbook with 320mb of ram. full xfce desktop with kde and gnome libs. It took a very long time to compile everything but it all worked just fine. I see no reason why you couldn't install lfs on that box just be patient.

I will be patient. Now I scrubbed from some drawer in my workshop an old 10 GB hdd (to provide some more space) and I will transfer old disk image to it and get started with LFS.

And I also think I will try to compile it on my main system first and then transfer it to this machine.

Thanks.

Hello !

Well, I checked few hours ago: on Quad core my main system (OpenSuSE) recognizes platform as Intel_64 so I will employ cross-compiler.

Thank you,

Josip
