 --------------------------------
 Symptoms:
-  Seemingly native toolchains do not build.
-
-Explanations:
-  Seemingly native toolchains are toolchains that target the same architecture
-  as the one it is built on, and on which it will run, but the machine tuple
-  may be different (eg i686 vs. i386, or x86_64-unknown-linux-gnu vs.
-  x86_64-pc-linux-gnu).
-
-  This seems to happen when building glibc-2.7 based toolchains only, for
-  x86 and for x86_64.
-
-  Only the system part of the tuple (here, linux-gnu) needs to be the same to
-  trigger the bug. Which means that building a tolchain for either x86 or
-  x86_64 on either x86 or x86_64 breaks.
-
-Fix:
-  None known.
-
-Workaround:
-  It seems that using -O2 in the CFLAGS fixes the problem. It has been
-  confirmed in the following threads:
-    http://sourceware.org/ml/crossgcc/2009-09/msg00055.html (for glibc)
-    http://sourceware.org/ml/crossgcc/2009-10/msg00001.html (for eglibc)
-
---------------------------------
-Symptoms:
   gcc is not found, although I *do* have gcc installed.

-Seemingly-native toolchains are toolchains that target the same architecture
-as the one it is built on, and on which it will run, but the machine tuple
-may be different (eg i686 vs. i386, or x86_64-unknown-linux-gnu vs.
-x86_64-pc-linux-gnu). This also applies if the target architecture is of the
-same kind (eg. x86 vs. x86_64, or ppc vs. ppc64).
-
-Such toolchain is tricky to build, as the configure scripts may incorrectly
-assume that files (headers and libs) from the build (or host) machine can be
-used by the cross-compiler it is going to build. The problem seems to arise
-only with glibc (and eglibc?) starting with version 2.7.

[PATCH 0 of 1] Remove documentation references to the seemingly native toolchain issue

[Richard Strand]

Hi Yann,

I've created a patch which removes the references in the documentation to the
seeming native toolchain issue. This is because the issue seems to be fixed
now that glic and eglibc are hard-coded to compile with -O2.

I know this is a fairly trivial patch and I mainly created it to test
mercurial, but it doesn't make sense to list this as an issue if it isn't.

Regards,

Richard Strand

You did perfectly OK. Thank you!
