    1212packages are built in chroot.

    14   pros:: no /tools symlink, no need to tweak gcc sources, no need to build twice ld in binutils-pass2, no need to readjust the toolchain after chapter 6 glibc, no need to tweak the gcc specs, no need to reinstall kernel headers in chapter 6.

    16   cons:: chroot is entered in the middle of chapter 5 (maybe chapter 5 should be split), the debug sections of several packages reference x86_64-lfs-linux-gnu instead of x86_64-pc-linux-gnu, binutils-pass2 needs "enable-shared".

    5353 Issue::
    5454  In the first phase of chroot terminal is not quite usable (no backspace key etc).
    55  Solution::
    56   remove "--disable-db-install" from the ncurses chap5 configure
    57 
     55 Solutions::
     56  - remove ''--disable-db-install'' from the ncurses chap5 configure. This means that '''tic''' should be present on the host with a suitably recent version (>= 6.0)
     57  - build '''tic''' from the ncurses package with build host tools, and use it to compile the terminfo database when cross-building ncurses
     58  - build with ''--disable-db-install'' and copy the /usr/share/terminfo database from the build host to the target lfs host (taints target in some way, who knows what is exactly in that database?).
     59  - build with ''--disable-db-install'', then run the built '''tic''' to install the terminfo database (taints cross compile, but the most economical)

    9698 Solution::
    9799  <currently none>
     100 Discussion::
     101  There are only warnings, then the error is about a missing file when running the m4 subprocess. To troubleshoot: '''type m4''' and '''ldd /usr/bin/m4''', also try to run bison with a verbose switch.
     102
     103  For the '''tar''' issue, is it in a pipe? The mailing list thread concluded that it was related to a change in the way the SIGPIPE signal was handled.
