Removed the locale check as it is now irrelevant. Removed the experimental binutils 2.17.50.0.xx: 2.18 is here now.

When configuring a s390->s390 or cris->cris crosscompiler
|
|
(ok, I haven't hit this yet, but one of these days I'll get me an account
|
|
on an s390, and then I'll need this patch :-), you'll get the
|
|
following error:
|
|
|
|
+ /build/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2/gcc-3.3/configure
|
|
--target=s390-unknown-linux-gnu --host=s390-host_unknown-linux-gnu
|
|
--prefix=/result/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2
|
|
--enable-languages=c
|
|
--with-local-prefix=/result/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2/s390-
|
|
unknown-linux-gnu --enable-threads=no --without-headers --with-newlib
|
|
--disable-shared
|
|
...
|
|
*** --with-headers is only supported when cross compiling
|
|
|
|
This error pops up only when you're using Daniel Jacobowitz's technique
|
|
of slightly changing the target and host tuples to make them different
|
|
enough to force gcc's build system to not try to pull in system libraries
|
|
or headers. This technique is needed e.g. to build an x86 -> x86
|
|
cross-compiler.
|
|
(The LFS developers ran into the same bug that prompted me to use
|
|
this technique; they point people who run into it to
|
|
http://linuxfromscratch.org/~greg/pure_lfs.txt, which is a different
|
|
way of avoiding this problem. I think the tuple tweak is the way to go, though.)
|
|
|
|
config-patches@gnu.org rejected this patch, on the grounds that there
|
|
is only one vendor of each of those two architectures, so the
|
|
canonicalization is by definition correct. When I pointed out the
|
|
difficulty this causes for people building s390 -> s390 or
|
|
cris -> cris compilers that are incompatible with the system
|
|
libraries and thus must be built like cross-compilers, he grumped and said
|
|
"autoconf should let you specify a cross-compiler in some other way than
|
|
comparing tuple strings".
