Re: Error building 32 bit on 64 bit linux system

Thanks Andrew, I missed the little -o in front of the SUBSYS.o. I did
find that if I did "export LDEMULATION=elf_i386" I was able to link
successfully. Now I just need to tell configure that I want to use the
32 bit perl libs, not the 64 bit ones it keeps finding by using:

$PERL -MConfig -e 'print $Config{archlibexp}'

Both 32 and 64 bit libraries are installed on my system, but the return
from the above command within configure points to the 64 bit libs, as
the perl executable is a 64 bit file. I think my better option is to
build my 32 bit versions on a 32 bit CentOS VM I have setup.
