Linking 64 library dependent on other libraries

Question

I am trying to create a 64 bit library (library A) that uses another 64 bit library (library B) that I have created.
The 64 bit library (library A) I am trying to create fails with the message that the second library (library B) is in the wrong ELF class: ELFCLASS32.
Development directory structure is:
B - ELF 32-bit MSB dynamic library location (libB.so)
|--- sparcv9 - ELF 64-bit MSB dynamic library location (libB.so)
A
|--- sparcv9
when I compile and link libA I used the following commands for the 32 and 64 bit from directory A
cc -xO2 -c A.c
cc -xO2 -xarchv9 -c -o sparcv9/A.o A.c
ld -G -B dynamic -o libA.so A.o -L../B -lB
ld -G -B dynamic -64 -o sparcv9/libA.so sparcv9/A.o -L../B -lB
The 32 bit library builds fine but the 64 bit library fails with libB being in the wrong ELFCLASS. If I move the 64 bit version of libB to /usr/lib/sparcv9 and run
ld -G -B dynamic -64 -o sparcv9/libA.so sparcv9/A.o -lB
It works and produces the 64 bit library. Am I missing something ??
thanks,
