GCC-3.0.1 can't compile Glibc-2.2.4

[william]

Hi,
        After I built GCC-3.0.1 compiler,I want to use it to compile
glibc-2.2.4,when configuring:
        CC=mipsel-linux-gcc AR=mipsel-linux-ar
RANLIB=mipsel-linux-ranlib BUILD_CC=gcc ../configure --prefix=/usr/local
--host=mipsel-linux --enable-add-ons=linuxthreads --enable-profile
        compiler told me below message:
        .......
    checking for mig... mig
configure: warning:
*** These auxiliary programs are missing or too old: msgfmt
*** some features will be disabled.
*** Check the INSTALL file for required versions.
*** This version of GNU libc cannot be compiled by GCC 3.x.
*** GCC 3.x will generate a library that is binary incompatible to
*** older and future releases of GNU libc.
*** You should compile this GNU libc release by an older GCC version
*** or wait for the next GNU libc release.
*** If you really mean to use GCC 3.x, run configure again
*** using the extra parameter `--disable-sanity-checks'.
            What does  it mean?GCC-3.0.1 can't compile glibc-2.2.4
Best regards

No, it can't, unfortunately.
Neither 2.95.3 or any other officially releasead GCC is completely ok, for
that matter.
To the best of my knowldedge you may:
1- Wait for the first 3.0.x/2.2.x couple certified as compatible (a couple
of months away?)
2- Apply a couple of patches to 2.95.3 (see, f..i,
http://gcc.gnu.org/ml/gcc/2001-06/msg01985.html ) or download a 2.95.4
snapshot (or wait for 2.95.4 itself)
3- Use 2.96-RH

(Personally, I chose 2- and everything went fine)

If someone in the know (f.i., H.J. Lu, A. Jaeger, J. Jelinek) would like to
post an update on this obnoxious issue we  - the users of both those GNU
packages - would all be very grateful!

Regards,
Paolo Carlini.

Hi,
        I check the patch against gcc-2.95.3,I'm wondering if it's only used for
i386 and alpha target.I wanted to get GCC-2.95.3 with those patch can work on
MIPS platform.Could it be available?
        Thanks for advance

There are close interactions between GCC and GLIBC which haven't been
solved completly yet for GCC 3.  Just don't compile glibc with GCC 3,
wait for a future release.
