llvm dev - Oct 2008 - [LLVMdev] Error while creating ExecutionEngine

Hi,

I am completely new to llvm. I am trying to build an optimization pass. I need
to interpret some instructions in the pass. To begin with, I used the exact same
code as HowtoUseJIT example. It compiles fine. While executing using opt, I get
the following error at the point where th executionengine is created:
opt: symbol lookup error: ../../../Release/lib/Try.so: undefined symbol:
_ZN4llvm15ExecutionEngine6createEPNS_14ModuleProviderEbPSs

I tried looking in the archives but could not find any similar problem.
Please let me know what I am doing wrong. Please let me know if it is possible
to create an object of executionengine in the optimization pass?

Thanks,
bhavani

I'm not 100% sure, but I think that you will have to have opt load up  
the LLVMExecutionEngine.o library.

-bw

Thanks Bill! But it does not work. I get the error given below when I try to
load LLVMExecutionEngine.o in the opt command.

Error opening '../../../build/Release/lib/LLVMExecutionEngine.o':
../../../build/Release/lib/LLVMExecutionEngine.o: only ET_DYN and ET_EXEC can be
loaded
  -load request ignored.

Any ideas?? Please help me out here.

Thanks,
Bhavani
