Good tutorial for building a toolchain?

I'm trying to build a sparc64-unknown-linux-gnu toolchain but just about every tutorial or script I use runs into problems. Anyone know of a site that'll help me successfully build a toolchain?

<[R]> what, is this 1999?
<Synthead> following LFS
<Synthead> "This chapter includes a list of packages that need to be downloaded for building a basic Linux system.

<[R]> Synthead: what ancient version of lfs are you using that you are using 2.6.24
<Synthead> [R], http://cross-lfs.org/view/1.1.0/sparc64/index.html
<[R]> thats pretty ancient
<[R]> good luck with that
<DrPenguin> the newer versions of LFS still recommend older 2.6.x kernels
<[R]> i just did 'read online' for the 'stable' version
<[R]> and it had 3.1
<Synthead> [R], for sparc64?
<[R]> Synthead: no, for normal lfs
<[R]> Synthead: if the latest version of the guide is that old... i woudlnt want to use old crap
<Synthead> [R], I'm just trying to follow chapter 5 to build a cross-compiling toolchain
<Synthead> [R], then I'm going to compile my own distro with it
<reisio> seems like the unnecessarily hard way to do an LFS

Why aren't you using the development version?

http://cross-lfs.org/view/svn/sparc64-64/

Everybody knows the stable is ancient .

I believe they have their own IRC channel(s) as well btw, always worth checking out.

Alright! I built a toolchain from the development version of sparc64 multilib. But now I'm running into a problem. I compiled hello.c (hello world, what else?) using sparc64-unknown-linux-gnu-gcc and scp'd it to my sparc system (running Debian). When trying to run it, I discovered that it's looking for "/tools/lib64":

$ ./hello
-bash: ./hello: No such file or directory
$ ldd hello
        libc.so.6 => /lib64/libc.so.6 (0xfffff801aace4000)
        /tools/lib64/ld-linux.so.2 => /lib64/ld-linux.so.2 (0x0000010000000000)
$ sudo mkdir /tools
$ sudo ln -s /lib64 /tools/lib64
$ ./hello
hello, world

What now?

You compiled it with the cross-toolchain. The procedure is: use the native toolchain to build the cross-toolchain, then use that toolchain to bootstrap, and once you can boot into that system, you can use it to build native sparc64 binaries. I told you in your other thread you needed to bootstrap a system, not just compile a toolchain.

If the CLFS guys could skip that step, don't you think they would do it?
