Looks like something went wrong while compiling libstdc++. the file "new"
should be installed in /tools/x86_64-lfs-linux-gnu/include/c++/9.2.0/
To check, first try:
find /tools -name new # should answer the above
If it is found, check that /tools/bin/x86_64-lfs-linux-gnu-g++ is able to find
it:
echo 'int main () { }' | /tools/bin/x86_64-lfs-linux-gnu-g++ --verbose -xc++
and check the lines beginning at "#include <...> search starts here" in the
output. There should be a line like
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/9.2.0/../../../../x86_64-lfs-linux-gnu/include/c++/9.2.0
If it is not there, something went wrong while compiling gcc-pass1. I guess
the best is to start over.
If it is not found, try rebuilding libstdc++, and try again the commands
above. If everything is OK, rebuild binutils pass2, then gcc pass 2.
But before that, check that the environment of user lfs is correctly set.
