[llvm-dev] FunctionPass failing with undefined symbol

[hi via llvm-dev]

I am trying sample Hello.cpp FunctionPass but while executing observing
following error:
Error opening './libHello.so': ./libHello.so: undefined symbol:
_ZNK4llvm12FunctionPass17createPrinterPassERNS_11raw_ostreamERKNSt3__112basic_stringIcNS3_11char_traitsIcEENS3_9allocatorIcEEEE

Steps:

1. clang++ -fPIC -shared -o libHello.so -o libHello.so Hello.o

2. clang++ -emit-llvm test.cpp -c -o test.bc

3. opt -load ./libHello.so -hello -disable-output test.bc

Please let me know if I missed any intermediate step.


Thanks,
