Then use the tools to install packages. Something like: - sudo apt-get update sudo apt-get install build-essential - should lead you close to a working environment. Run version-check.sh and look for missing packages. Then "apt-get install" them.

The problem with me is that I don't know enough about Linux to know what to do next. Since Knoppix is listed as a choice for a host system in the FAQ, I assume there is a way to build LFS using Knoppix as a host. What I don't know is how to add the missing package(s) so they will work with Knoppix to build the LFS packages I need. I am using Knoppix as a live disk, not as an installed operating system, and it escapes me how to add a package.

I don't know how to break this to you, but 2GHz is not considered
fast. Also, building with only 256 MB of RAM sounds very painful (I
haven't built LFS on less than 1GB RAM for several years), so I
imagine that the build process will take a long time.
Below is the Make output just before it quits.
Tail of Make output before failure:
checking how to run the C++ preprocessor. . . /lib/cpp
configure: error: in '/mnt/lfs/sources/gcc-6.3.0/build/gcc':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See 'config.log' for more details.
Unfortunately, in gcc and binutils (and probably a few other
packages) there are config.log files in several subdirectories.
What you need is the one that has the text 'fails sanity check' in
it. Should be the newest config.log file, and you can search it (or
all of them, if the timestamps are the same) using 'view' or 'less'
e.g. /\/lib\/cpp ('/' searches in less and vim, I expect you
probably know that).
Unfortunately, I was not able to read any config.log files other than
the one attached to the first post.
When you find the error message, the details are in the lines above
that, probably no more than 40 or 50 lines. You should see
configure putting out the message that it is checking how to run the
C++ processor, creating something to do that, and then reporting a
detailed error, followed by the message that it fails sanity check.
It is the detailed error message(s) from trying to run whatever
configure generated which will provide the details.
ĸen
To me, it appears the problem is it can't find a C++ preprocessor. I am
installing GCC-6.3.0 and I thought it was supposed to provide the
package it is looking for. It seems like a circular reasoning loop to
me: 'I need the C++ preprocessor to build the C++ preprocessor.' I am
not that sharp in Linux, as I have only been doing Linux for a couple
years, and mostly with self-installing distributions (Cinnamon Mint,
Slackware). I started try to install LFS to learn more about Linux, but
so far, I am getting an 'F'. Any help would be appreciated.
