Everything seemed to be running correctly before I ran the script below. Unfortunately, I got no output from this command.

Caution

At this point, it is imperative to stop and ensure that the basic functions (compiling and linking) of the new toolchain are working as expected. To perform a sanity check, run the following commands:

echo 'main(){}' > dummy.c
cc dummy.c
readelf -l a.out | grep ': /tools'

If everything is working correctly, there should be no errors, and the output of the last command will be of the form:

[Requesting program interpreter:
/tools/lib/ld-linux.so.2]

what is the best way to proceed from here.

Did you adjust the toolchain before?
Also, I found that it seems to be necessary to adjust the toolchain again after install GCC for the second time.

I have re-adjusted the chain everywhere it has been asked for so far. I did try to re-adjust again and have the same no output. I think I really screwed it up now though. Last night when I ran the $PATH command I was close with output of /tools/bin/usr/bin and this morning I have /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin. Can I just go back and delete gcc-build and start this sequence (5.10)over or am I too far into process for that?

Well, it's important that all variables that have been set before you started the installation are maintained throughout the installation-process, unless instructed to unset of course.

Having built LFS a couple of times and having a LFS-based distro myself I'd suggest restarting from the beggining if now it's not possible to re-adjust the toolchain again in order to get the test linking to the proper place.

Also, if you end up with a directory /tools/usr/bin there's something wrong already, there should be no usr under /tools.

Anyway, you're not that far into the installation yet. Of course it took quite a while, but most work is still ahead of you.

Ok I solved the problem. First I deleted gcc-build and tried it again. That didn't solve the problem. So since I know I had the right result before the second pass of binutils-guild, I deleted binutils-build pass2 and gcc-build pass2 and redid them. I came up with the right result without having to reformating.
