Hi John,

excellent someone trying the 64 bit ness of gm2!

interesting, the file mod_init.o is created each time a sub program
of gm2 is created (gm2l, gm2lsub etc). It looks as if an older version
of the object file is being picked up at link time during
gm2.paranoid.

It would be interesting to see if a strict 64 bit build and
gm2.paranoid is successful. I wonder whether you could try adding
--disable-multilib to the configure options. Also it would be good to
double check that the build directory has been rm -rf 'ed before
attempting a build. I tend to build the compiler outside of the source
tree - so that I can remove it totally before the next recompile.

Here is my simple shell script which I use to build gm2 on the
opteron:

#!/bin/sh

DIR=/home/gaius/GM2/build-opteron

if [ -d $DIR ] ; then
   cd $DIR
   rm -rf *
   ../gcc-3.3.4/configure --disable-multilib --enable-languages=c,gm2 
--enable-checking
   time make
else
   echo "cannot find directory $DIR"
   exit 1
fi

Let us know how you get on!

Thanks Gaius
