    Explanations:
yann@771
    16
      An as much as possible in-depth explanations of the context, why it
yann@771
    17
      happens, what has been investigated so far, and possible orientations
yann@771
    18
      as how to try to solve this (eg. URLs, code snippets...).
yann@771

yann@771
    20
    Fix:
yann@771
    21
      What you have to do to fix it, if at all possible.
yann@771
    22
      The fact that there is a fix, and yet this is a known issue means that
yann@771
    23
      time to incorporate the fix in crosstool-NG was missing, or planned for
yann@771
    24
      a future release.
yann@771
    25
yann@771
    26
    Workaround:
yann@771
    27
      What you can do to fix it *temporarily*, if at all possible.
yann@771
    28
      A workaround is not a real fix, as it can break other parts of
yann@771
    29
      crosstool-NG, but at least makes you going in your particular case.
yann@771
    30
yann@771
    31
So now, on for the real issues...

Symptoms:
yann@771
    35
  Seemingly native toolchains do not build.
yann@771
    36
yann@771
    37
Explanations:
yann@771
    38
  Seemingly native toolchains are toolchains that target the same architecture
yann@771
    39
  as the one it is built on, and on which it will run, but the machine tuple
yann@771
    40
  may be different (eg i686 vs. i386, or x86_64-unknown-linux-gnu vs.
yann@771
    41
  x86_64-pc-linux-gnu).
yann@771
    42
yann@771
    43
  This seems to happen when building glibc-2.7 based toolchains only, for
yann@771
    44
  x86 and for x86_64.
yann@771
    45
yann@771
    46
  Only the system part of the tuple (here, linux-gnu) needs to be the same to
yann@885
    47
  trigger the bug. Which means that building a tolchain for either x86 or
yann@885
    48
  x86_64 on either x86 or x86_64 breaks.
yann@771
    49
yann@771

Fix:
yann@771
    51
  None known.
yann@771
    52
yann@771
    53
Workaround:
yann@771
    54
  If this happens for you, stick with glibc-2.6.1 for now.
yann@771
    55
  Or investigate! :-)

  gcc is not found, although I *do* have gcc installed.
yann@885

yann@885
    61
Explanations:
yann@885
    62
  This is an issue on at least RHEL systems, where gcc is a symlink to ccache.
yann@885
    63
  Because crosstool-NG create links to gcc for the build and host environment,
yann@885
    64
  those symlinks are in fact pointing to ccache, which then doesn't know how
yann@885
    65
  to run the compiler.
yann@885
    66
yann@885
    67
  A possible fix could probably set the environment variable CCACHE_CC to the
yann@885
    68
  actual compiler used.

Explanations:
yann@1218
    81
  This is not related to crosstool-NG. Mounts under Cygwin are by default not
yann@1218
    82
  case-sensitive. You have to use so-called "managed" mounts. See:
yann@1218
    83
  http://cygwin.com/faq.html section 4, question 32.
yann@1218
    84
yann@1218
    85
Fix:
yann@1218
    86
  Use "managed" mounts for the directories where you build *and* install your
yann@1218
    87
  toolchains.
yann@1218

  With uClibc, it is possible to build a cross-ldd. Unfortunately, it is
