LibGCJ static linking trouble

Wed Nov 15 17:40:00 GMT 2006

Hello all.
I'm following the instructions in
 http://gcc.gnu.org/wiki/Statically%20linking%20libgcj
for compiling things so that they don't need libgcj.so at runtime.
The final link-it-all-together line in my makefile is (remove carriage 
returns as needed)
$(EXECOUT)/%: %-adaptor.o globalphasing/maketnt/%.o $(maketntlibs) $(javalibs)
 $(GCJ) -o $(EXECOUT)/$* $^ -shared-libgcc 
-Wl,-non_shared -lgcj -Wl,-call_shared -lsupc++ -Wl,--as-needed -lz 
-lgcc_s -lpthread -lc -lm -ldl -Wl,--no-as-needed
where %-adaptor.o contains main(), which calls various bits of C code 
which do some setup and then calls into the compiled java following the 
model of
 http://www-ti.informatik.uni-tuebingen.de/~thiele/cni/
Unfortunately, whilst this produces enormous executables

-rwxr-xr-x 1 twomack cdrom 8260516 2006年11月15日 17:34 toadfarm/bin/linux/PDB2TNT
they don't appear to be statically linked:

Can you help?
