There are very bad suggestions in this /tutorial/:

  - manually editing the .config file
    This is a Bad Thing (TM).
    The configuration of crosstoll-Ng is done by running one of the
    configurators:
        ct-ng menuconfig
    or:
        ct-ng nconfig

    Options are set in the .config file because they've been set in the
    menuconfig. Manually overrding them is wrong. The configuration must
    be fixed from menuconfig.

  - Static linking impossible on the host system [...]
    The solution is wrong.

    This error is because something in crostool-NG wants to do some
    static linking. This should be disabled, using the menuconfig.
    In this case, the option wanting the static link is:
        CT_CC_STATIC_LIBSTDCXX
    which is selected in:
        C compiler  --->
            [*] Link libstdc++ statically into the gcc binary

    If you disable this option, then static linking is no longer
    needed, and this error will vanish. Also, the '-Bstatic' issue will
    also disapear.

    We now have better code and error messages in the repository for this
    problem. It will be available in the next release.

  - gdb's 'readchar: Got EOF' error:
    Do not edit the .config file manually. Use 'ct-ng menuconfig' to change
    the config options.

If you know how to contact the author, then please forward him/her this
mail, and tell him/her to ask for help on the mailing list. We're usually
trying to answer issues as much as we can (but being a volunteer endeavour
for me, it's on a time-permit basis; others can/will help, too).

Regards,
Yann E. MORIN.
