Can you tar up your module and send it to me and I will see if I can
determine what you may be having problems with?

David,
Thanks for the info on linux shared libraries. I
compiled and linked using the Makefile below.
Unfortunately, on execution the results are the same as
with inlining; same "ignoring redefinition" messages
and same "function does not exist" message.

For Linux its actually quite easy. Using a similar setup, shown below:
BASE = /usr/local/dx
LDFLAGS = --shared -eDXEntry
CFLAGS = -I$(BASE)/include
LIBS = "$LIBS -L$(BASE)/lib_$ARCH"
CC = cc
OTI_loadable: $(OBJ)
$(CC) $(LDFLAGS) $(OBJ) $(LIBS) -o OTI_loadable
Of course you may need to add more libraries.
