Build failure of GCC-3.0 branch on powerpc

Build failure of GCC-3.0 branch on powerpc

[Mark Wielaard]

Hi,

I am trying to build the GCC 3.0 branch on powerpc including gcj.
It is the CVS version of yesterday configured with --enable-languages=c++,java
It gives the following error:

make[6]: Entering directory `/opt/mark/gcc-obj/powerpc-unknown-linux-gnu/nof/libffi'
/bin/sh ./libtool --mode=link /opt/mark/gcc-obj/gcc/xgcc -B/opt/mark/gcc-obj/gcc/ -B/usr/local/gcc/powerpc-unknown-linux-gnu/bin/ -B/usr/local/gcc/powerpc-unknown-linux-gnu/lib/ -isystem /usr/local/gcc/powerpc-unknown-linux-gnu/include  -msoft-float -fPIC -mstrict-align -fexceptions -g -O2  -msoft-float -fPIC -mstrict-align -msoft-float -fPIC -mstrict-align -o ffitest  ffitest.o libffi.la

Someone suggested that configuring with --disable-multilib could be a
workaround. But that gives me the following error:

Could someone help me analyse this problem?
I can build a functional gcj compiler on i386.

Thanks,

Mark

Some updates. It still doesn't work :(
The libgcc_s_nof.so.0 file does exist.

I tried a clean build without gjc but with g++ (--enable-languages=c++).
That does seem to succeed but after I installed it I couldn't compile
even the simplest c++ program. I always get the following:

/usr/local/gcc/lib/gcc-lib/powerpc-unknown-linux-gnu/3.0/../../../libgcc_s.so: undefined reference to `__SBSS2_END__'
/usr/local/gcc/lib/gcc-lib/powerpc-unknown-linux-gnu/3.0/../../../libgcc_s.so: undefined reference to `__init'
/usr/local/gcc/lib/gcc-lib/powerpc-unknown-linux-gnu/3.0/../../../libgcc_s.so: undefined reference to `__SBSS_END__'
/usr/local/gcc/lib/gcc-lib/powerpc-unknown-linux-gnu/3.0/../../../libgcc_s.so: undefined reference to `__SDATA2_START__'
/usr/local/gcc/lib/gcc-lib/powerpc-unknown-linux-gnu/3.0/../../../libgcc_s.so: undefined reference to `__SDATA_START__'
collect2: ld returned 1 exit status

The g++ compiler (also compiled from the same CVS source)
does work on my i386 machine.

Could someone help me getting this working on powerpc?
Does anybody have a working g++ and/or gcj compiler from recent
CVS (3.0 branch)?

Thanks,

Mark
