With my experience, a few posts down.
First pass of gcc in a cross compiler, you have to disable both threads
and shared. Problem is that both depend on files that you only create
when you compile your target C library, and you can only compile that
when you've a basic compiler working.
So first compile with --disable-shared --disable-threads
Then do your C lib
Then recompile with shared and threads enabled, and making sure you are
pointing things to the new files created by the C lib ....
Hope this helps,
David.

I am trying to build a cross-compiler with gcc-4.7.0 from Ubuntu Linux
to AIX6.1
I have build the binutils (2.22) OK
I have copied the include files and /usr/lib contents from AIX6.1 to
/home/crossenv/powerpc-ibm-aix6.1/include and .../lib
I am running:
../gcc-4.7.0/configure --target=powerpc-ibm-aix6.1
--prefix=/home/crossenv --disable-nls --enable-languages=c,c++
make all-gcc
make install-gcc
make all-target-libgcc
However it gets as far as the following on the last step
/bin/bash ../../../../gcc-4.7.0/libgcc/../mkinstalldirs
../../.././gcc/pthread
/usr/bin/install -c -m 644 libgcc_eh.a ../../.././gcc/pthread/
chmod 644 ../../.././gcc/pthread/libgcc_eh.a
/home/crossenv/powerpc-ibm-aix6.1/bin/ranlib
../../.././gcc/pthread/libgcc_eh.a
/bin/bash ../../../../gcc-4.7.0/libgcc/../mkinstalldirs
../../.././gcc/pthread; /usr/bin/install -c -m 644 pthread/libgcc_s.a
../../.././gcc/pthread/
/usr/bin/install: cannot stat `pthread/libgcc_s.a': No such file or
directory
I don't need threads straightaway, can I bypass this just to get off the
ground?
Thanks for any help people can give.
