I have determined why there are many "WARNING: Duplicate symbol:" messages.
*** My apologies for the length *** There is a lot of detail - but I
hope the detail will help R - and others - setup correct options for
shared libraries.
*** As I press send, I have not stopped testing (my final trial here
might not even work) - but!
*** the message is that shared libraries do not need to have all
external libraries on the command line to make a shareable library
(that is the whole point of multiple shared libraries I think)
Anyway, I hope you are"in" for a long read.
a) the duplicate symbol messages occur during the creation (read
linking) of a shared object.
b) the shared object does not need to have all symbols resolved -
actually, you do not want "external" symbols from elsewhere pulled
into to the archive.
c) one example - stats.so
currently the command to make stats.so is:
gcc -Wl,-bnoquiet -std=gnu99 -shared -Wl,-brtl -Wl,-G -Wl,-bexpall
-Wl,-bnoentry -o stats.so init.o kmeans.o ansari.o bandwidth
s.o chisqsim.o d2x2xk.o fexact.o kendall.o ks.o line.o smooth.o prho.o

lm /opt/lib/gcc/powerpc-ibm-aix5.3.0.0/4.7.4/libgcc.a -lg -lm
/opt/lib/libintl.a /opt/lib/libiconv.a -lpthread
The result has duplicate symbols:
