[LLVMdev] Function "llvm::PassManager::run" not defined.

[suyog sarda]

Are you able to run your pass successfully? Are you getting this error only
while debugging?

Hi,

I am trying to use GDB for debugging my llvm pass. I am following the
documentation http://llvm.org/docs/WritingAnLLVMPass.html
<https://urldefense.proofpoint.com/v2/url?u=http-3A__llvm.org_docs_WritingAnLLVMPass.html&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=5-XncfQlc7dFtxPaBLgmnmyWuvZMhrLR_5nxoY-JD20&s=SrFgJEHbETmgWTO9pAyW4ScBlT2tCBFGhzZG-Oi2ArI&e=>.
When i am doing this the following error and warning messages I am getting.
I tried to remove the warning by apt-get install libc6-dbg:i386 command for
updating the libc6 but still getting the same.

This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.
