Undefined reference to `TDatabasePDG::Instance()

Hi, Everyone, I have the problem:

make main112
g++ main112.cc main112.so -o main112 -w -I/opt/root6/include -I../include -O2  -pedantic -W -Wall -Wshadow -fPIC -L../lib -Wl,-rpath,../lib -lpythia8 -ldl \
 `root-config --cflags` -Wl,-rpath,./\
 -Wl,-rpath,/opt/root6/lib `/opt/root6/bin/root-config --glibs`
/tmp/ccnQiqUQ.o: In function `HxSimParticle::GetPDG()':
main112.cc:(.text+0x91a): undefined reference to `TDatabasePDG::Instance()'
main112.cc:(.text+0x925): undefined reference to `TDatabasePDG::GetParticle(int) const'
collect2: error: ld returned 1 exit status
Makefile:202: recipe for target 'main112' failed
make: *** [main112] Error 1


FLAGS = -w -I/opt/root6/include -I../include -O2  -pedantic -W -Wall -Wshadow -fPIC -L../lib -Wl,-rpath,../lib -lpythia8 -ldl  `root-config --cflags` -Wl,-rpath,./ -Wl,-rpath,/opt/root6/lib `/opt/root6/bin/root-config --glibs`

ROOTLIBS += -lEG -lGui -lASImage -lASImageGui

main112: $$@.cc $(PREFIX_LIB)/libpythia8.a main112.so
ifeq ($(ROOT_USE),true)
	$(CXX) $< main112.so -o $@ -w -I$(ROOT_INCLUDE) $(CXX_COMMON)\
	 `$(ROOTBIN)root-config --cflags` -Wl,-rpath,./\

main112Dct.cc: main112.h HxSimParticle.h HxSimEvent.h main112LinkDef.h
	 $(ROOT_BIN)rootcint -f $@ -c -I$(PREFIX_INCLUDE) $^

Someone know what am I doing wrong?
