glibc compilation error
I am trying to cross compile GCC for an AMCC 440SP platform (powerpc-linux). Binutils and bootstrap GCC compile fine, but when I make glibc it errors out with the following: snippet if test -r /opt/luan2/toolchain/build/glibc/csu/abi-tag.h.new; then mv -f /opt/luan2/toolchain/build/glibc/csu/abi-tag.h.new /opt/luan2/toolchain/build/glibc/csu/abi-tag.h; \ else echo >&2 'This configuration not matched in ../abi-tags'; exit 1; fi gawk -f ../scripts/gen-as-const.awk ../linuxthreads/sysdeps/powerpc/tcb-offsets.sym \ | powerpc-linux-gcc -S -o /opt/luan2/toolchain/build/glibc/tcb-offsets.hT3 -std=gnu99 -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g -mnew-mnemonics -I../include -I. -I/opt/luan2/toolchain/build/glibc/csu -I.. -I../libio -I/opt/luan2/toolchain/build/glibc -I../sysdeps/powerpc/powerpc32/elf -I../sysdeps/powerpc/elf -I../linuxthreads/sysdeps/unix/sysv/linux/powerpc/powerpc32 -I../linuxthreads/sysdeps/unix/sysv/linux/powerpc -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/powerpc32 -I../linuxthreads/sysdeps/powerpc -I../sysdeps/unix/sysv/linux/powerpc/powerpc32 -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/powerpc32/fpu -I../sysdeps/powerpc/powerpc32 -I../sysdeps/wordsize-32 -I../sysdeps/powerpc/soft-fp -I../sysdeps/powerpc/fpu -I../sysdeps/powerpc -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /opt/luan2/toolchain/bin/lib/gcc/powerpc-linux/4.0.2/include -isystem /opt/luan2/toolchain/source/linux-2.6.13/include/ -D_LIBC_REENTRANT -include ../include/libc-symbols.h -DHAVE_INITFINI -x c - \ -MD -MP -MF /opt/luan2/toolchain/build/glibc/tcb-offsets.h.dT -MT '/opt/luan2/toolchain/build/glibc/tcb-offsets.h.d /opt/luan2/toolchain/build/glibc/tcb-offsets.h' : In function dummy: :11: warning: asm operand 0 probably doesnt match constraints :11: error: impossible constraint in asm make[2]: *** [/opt/luan2/toolchain/build/glibc/tcb-offsets.h] Error 1 make[2]: Leaving directory `/opt/luan2/toolchain/source/glibc-2.3.5/csu' make[1]: *** [csu/subdir_lib] Error 2 make[1]: Leaving directory `/opt/luan2/toolchain/source/glibc-2.3.5' make: *** [all] Error 2 snippet Here is the configuration I run from a separate build/glibc directory: ../../source/glibc-2.3.5/configure --prefix=/opt/luan2/toolchain/bin --target=powerpc-linux --host=powerpc-linux --enable-add-ons=linuxthreads --with-headers=/opt/luan2/toolchain/source/linux-2.6.13/include/ --with-binutils=/opt/luan2/toolchain/bin/powerpc-linux/bin This seems to complete without any issues.

HowTo Cross Compile GCC on x86 Host for PowerPC Target
Is there a HowTo out there on how to cross compile GCC to run on another platform? I have an x86 host running linux, and an embedded PowerPC 440SP target running linux. I would like to compile GCC to run on the target but am having some difficulties. I have compiled the cross compiler fine, but when I try to compile a native compiler, it acts just like the cross compiler (runs on the host and not the target). All I did was re-run gcc configure and "make all install". Here is the configuration I ran: ../../source/gcc-3.4.4/configure --target=powerpc-linux --host=powerpc-linux --prefix=/opt/luan2/toolchain/bin --enable-shared --enable-threads --enable-languages=c I'm obviously missing something, but can't seem to find anything on the internet that explains cross-compiling gcc for another target.

RE: HowTo Cross Compile GCC on x86 Host for PowerPC Target
Yes I added the cross-compiler to the path and created a separate build directory (ppc_gcc).

Re: Howto Cross Compile GCC to run on PPC Platform
I am using the AMCC 440SP processor. I went and
bought "Building Embedded Linux Systems" by Karim
Yaghmour. It seems to be a pretty complete book, and
I have gotten the cross-compiler completely installed,
but it doesn't get into installing a native compiler.
However, I tried cross compiling gcc by first running
this configure line:
../gcc-3.4.4/configure
--build=`../gcc-3.4.4/config.guess`
--target=powerpc-linux --host=powerpc-linux
--prefix=${PREFIX} --enable-languages=c
and then a make all. The make went fine, and
completed without any errors. However, when I ran
'make install' I got the following error:
powerpc-linux-gcc: installation problem, cannot exec
`/opt/recorder/tools/libexec/gcc/powerpc-linux/3.4.4/collect2':
Exec format error
make[2]: *** [nof/libgcc_s_nof.so] Error 1
make[2]: Leaving directory
`/opt/recorder/build-tools/build-native-gcc/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory
`/opt/recorder/build-tools/build-native-gcc/gcc'
make: *** [install-gcc] Error 2
How do I install the native compiler?
Thanks,
Jeff Stevens

Re: Howto Cross Compile GCC to run on PPC Platform
I am creating the target tree on my host, so that I
can later transfer it to a USB storage device. I was
going to manually move everything, but only saw one
binary, xgcc. Is that all, or aren't there some other
utilities that go along with it? I just didn't know
exactly what to copy and where to copy it to. When I
built glibc, those were built for the target system,
but installed to the target directory structure that I
am creating.
The 'make install' command that I ran for glibc was:
make install_root=${TARGET_PREFIX} prefix="" install
where TARGET_PREFIX is the target filesystem tree. I
used the same make install command for the native gcc
that I compiled.
Thanks,
Jeff Stevens
