Wild guess: you ran more/record-commands.sh then deleted build/host but  
not
build/record-commands ? (The logic for figuring out what the  
record-commands wrapper hands off to is still a bit brittle.)

If not, did you build via build.sh or via more/buildall.sh? (Let's see,  
clean pull, ./build.sh i686, and... that's going to take a while on  
this netbook.)

A) You don't need to build as root, it should work fine as a normal  
user.

B) The point of host-tools.sh is to setup build/host with known  
versions of everything the build needs, and then the rest of the build  
restricts the $PATH to that if it's there. Sounds like it's setting it  
up wrong. Let's see...

(The build can skip the host-tools.sh stage. Either comment it out in  
build.sh or run the stages yourself by hand skipping that one. But that  
doesn't fix the problem, host-tools _should_ be creating a good  
build/host directory...)

It's finished host-tools.sh here and is grinding away at binutils. I  
just stopped it and re-ran download.sh and it's happy.

What are the steps you used to reproduce this? Are you building the  
latest release version or a mercurial pull? Have you built in that  
directory before, or does it do it on your first attempt in a clean  
directory?

I'm happy to debug anything I can reproduce, but I need more info to  
reproduce this...

Sounds like a nice machine. I've built under funtoo before, but it was  
a while ago.

Ooh, very nice.

I was looking up sparc64 a while ago and it's another one like powerpc  
64 where they didn't bother to do a 64 bit userspace, just 64 bit  
kernels and the very occasional application. Thus I'm not quite sure  
how to add Aboriginal support to it. (Just a toolchain? Toolchain and  
kernel using the 32 bit userspace? Except how would you build the  
"occasional" 64 bit application? Where does libc enter into this?)

Then again, I'm told that's changing because gcc is dropping sparc32  
support:

(Of course current gcc requires a C++ compiler on the host to build it,  
so here's hoping clang/pcc/open64 matures quickly.)
