Compiling and linking with -instances=static gave me the following
output:
ld: fatal: symbol
`RefHashTableOfEnumerator<DTDAttDef>::~RefHashTableOfEnumerator
#Nvariant 1()'
is multiply defined:
(file /home/eyankowi/tmp/xerces-csrc_1_1_0_d05/obj/DTDAttDefList.o
and file
/home/eyankowi/tmp/xerces-csrc_1_1_0_d05/obj/DTDElementDecl.o);
ld: fatal: File processing errors. No output written to
/home/eyankowi/tmp/xerces-csrc_1_1_0_d05/lib/libxerces-c1_1.so
There may be a way to fix this error, but as Sun doesn't recommend this
method,
it may not be worth the effort.
