I'm trying to create a bootstrap gcc (3.0.4) on i686, target PPC (see thread at http://sources.redhat.com/ml/crossgcc/2002-05/msg00093.html ). The build fails due to some missing glibc header files. This appears to be the same problem as reported here:

A note there suggests a 'make install_headers' under glibc-2.2.5, *before* building the bootstrap gcc. This works until it reaches:

gcc rpc_main.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g -mnew-mnemonics -Wa,-mppc -mpowerpc -I../include -I. -I/home2/dimator/3rdParty/crosstools/glibc-ppc405/sunrpc -I.. -I../libio -I/home2/dimator/3rdParty/crosstools/glibc-ppc405 -I../sysdeps/powerpc/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/powerpc -I../sysdeps/unix/sysv/linux/powerpc -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/powerpc -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/powerpc/fpu -I../sysdeps/powerpc -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/powerpc/soft-fp -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /usr/lib/gcc-lib/i386-linux/2.95.4/include -isystem /home2/dimator/opt/ppc405/powerpc-linux/include/ -D_LIBC_REENTRANT -include ../include/libc-symbols.h -D_RPC_THREAD_SAFE_ -o /home2/dimator/3rdParty/crosstools/glibc-ppc405/sunrpc/rpc_main.o

So the 'install-headers' target wants to run gcc too, for some reason. Judging from the cc1 error lines, my guess is that it really wants to run the bootstrap gcc, with target=ppc. Anyone know what I'm doing wrong?

After grappling with this for a week now, I'm thinking of just resorting to the following: after building binutils, build a bootstrap gcc using gcc 2.95.3 (since that builds OK). Using that gcc, build glibc. Once glibc is in place, go back and build gcc-3.0.4. Kind of a drag, but if it works, I'll be satisfied.
