I have spent quite a bit of time trying to get a gcc 3.0 / glibc 2.2.3
cross-toolchain working. I am not a Toolchain Builder, but I really wanted
to try this combo and I don't see any way around building it myself.
I've had some success. Everything seems to build fine. However, when I try
to run a simple "hello world" dynamically linked with glibc, I get this:
<myprogram>: error while loading shared libraries: failed to map
segment from shared object: cannot load shared object file: Invalid
argument
I think it is trying to load libc.so.6, which is in my root in /lib/,
symlinked to libc-2.2.3.so, and so is ld.so.1, symlinked to ld-2.2.3.so.
I feel like I am pretty close, but I am starting to get discouraged and
could really use some help. I really am clueless about what
should/shouldn't work. I'm trying to do this based on bits and pieces of
information that I've collected from countless sources. I have heard that
gcc 3.0 isn't really "working", but I still want to try.
Here is what I've used:
* binutils-2.11.90.0.25.tar.gz (extracted from H. J. Lu's
srpm on oss.sgi.com; I've tried others also)
* gcc-3.0.tar.gz (released version - no patches)
* glibc-linuxthreads-2.2.3.tar.gz (released version - no
patches; glibc didn't want to configure without this)
* glibc-2.2.3.tar.gz (released version)
plus a tiny patch to glibc that looks like:

I built everything on my i386 Debian 2.2 box as follows:
Build the mipsel cross-binutils
tar -xzf binutils-2.11.90.0.25.tar.gz
mkdir mipsel-binutils
cd mipsel-binutils
../binutils-2.11.2/configure --target=mipsel-linux \
--libdir='${exec_prefix}'/mipsel-linux/i386-linux/lib
make
make install
cd ..
Build the mipsel cross-gcc:
tar -xzf gcc-3.0.tar.gz
mkdir mipsel-gcc
cd mipsel-gcc
../gcc-3.0/configure --target=mipsel-linux \
--enable-languages=c --disable-shared
make
make install
cd ..
Install the kernel headers
mkdir /usr/local/mipsel-linux/include
cp -r $LINUX_SRC/include/linux /usr/local/mipsel-linux/include
cp -r $LINUX_SRC/include/asm-mips /usr/local/mipsel-linux/include/asm
Build glibc:
tar -xzf glibc-2.2.3
cd glibc-2.2.3
patch -p1 -i../elf32-tradlittlemips.diff
tar -xzf ../glibc-linuxthreads-2.2.3.tar.gz
cd ..
mkdir mipsel-glibc
cd mipsel-glibc
../glibc-2.2.3/configure --build=i686-linux --host=mipsel-linux \
--enable-add-ons --prefix=/usr/local/mipsel-linux
make
make install
cd ..
Thanks.
