llvm dev - Jul 2015 - [LLVMdev] error open a share library generated by a LLVM pass

Hello,
use command :
opt -load ../Release+Asserts/XX.o -XX <packetbuf.bc> /dev/null

then I got the error by use the XX.o in the LLVM pass directory:
Error opening "../Release+Asserts/XX.o" only ET_DYN and ET_EXEC can be
loaded
-load request ignored.

 I got another error by use the XX.o in the LLVM src directory
$LLVM_SRC/Release+Asserts/lib/XX.o:
Error opening '../../Release+Asserts/lib/XX.so':
../../Release+Asserts/lib/XX.so: undefined symbol:
_ZN4llvm18EQTDDataStructures2IDE
  -load request ignored.

I installed LLVM-3.3 in ubuntu 12.04.5.  there are not errors when I make
the LLVM pass.

Anybody can help me? why I got these errors?

best regards,
zhaoqian

That mangled name refers to llvm::EQTDDataStructures::ID. Does your 
library define it?
