My error with this page, even after having built one or two versions of
LFS, was that the last line:
"gcc compilation OK"
that made me ignore the other lines, when some of these lines were
telling me that I had requirements to fix.
I thought: "all right, host can compile, so the other lines are just
additional information or recommendations, may be".
i had the same problem. so i reworked the script.
i moved the compile test after checking for gcc, and put linux at the
end, as there have to be checked 2 versions
the output does not only show min requirement, but the current version
the book builds too.
my script aborts if /bin/sh is not bash, awk not gawk or yacc not bison.
if awk or yacc are scripts, i show a message to check the script.
