GCC 3.4 on Mac OS X: compilable, but with problems


Hi!

1. I was able to successfully compile (bootstrap) GCC 3.4 on Mac OS X! Here the information:

uname -a
Darwin Bojan-Antonovics-Computer.local 7.3.0 Darwin Kernel Version 7.3.0: Fri Mar 5 14:22:55 PST 2004; root:xnu/xnu-517.3.15.obj~4/RELEASE_PPC Power Macintosh powerpc


gcc-3.4 -v
Reading specs from /usr/local/lib/gcc/powerpc-apple-darwin7.3.0/3.4.0/specs
Configured with: ./configure --enable-languages=java : (reconfigured) ./configure --program-suffix=-3.4 --enable-languages=c,c++,java
Thread model: posix
gcc version 3.4.0


/usr/bin/gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1635) (-mlongcall)

2. multiple definitions of symbol _sqrt:
When compling GCC 3.4, at the end the following report came:

creating rmic
/bin/sh ./libtool --tag=GCJ --mode=link /Volumes/Leopard/gcc-3.4.0/gcc/gcj -B/Volumes/Leopard/gcc-3.4.0/powerpc-apple-darwin7.3.0/libjava/ -B/Volumes/Leopard/gcc-3.4.0/gcc/ -L/Volumes/Leopard/gcc-3.4.0/powerpc-apple-darwin7.3.0/libjava -g -O2 -o rmiregistry --main=gnu.java.rmi.registry.RegistryImpl -rpath /usr/local/lib -shared-libgcc -L/Volumes/Leopard/gcc-3.4.0/powerpc-apple-darwin7.3.0/libjava/.libs libgcj.la

./.libs/libgcj.dylib(libgcj.5.0.0.dylib-master.o) definition of _sqrt
/usr/lib/libpthread.dylib(sqrt970.o) definition of _sqrt
creating rmiregistry


This seems to be commonly reported.

Also compiling HelloWorld.java produced the same problem:

gcj-3.4 --main=HelloWorld -o HelloWorld HelloWorld.java
/usr/bin/ld: warning multiple definitions of symbol _sqrt
/usr/local/lib/gcc/powerpc-apple-darwin7.3.0/3.4.0/../../../libgcj.dylib(libgcj.5.0.0.dylib-master.o) definition of _sqrt
/usr/lib/libm.dylib(sqrt970.o) definition of _sqrt


Bytheway: Call it with

./HelloWord

worked! Great job, people !!!

4. Building GCC 3.4 by

  % mkdir objdir
  % cd objdir
  % srcdir/configure [options] [target]

did _never_ work

greetings

Bojan
