[LLVMdev] LLVM Basic Program Compilation

[Prakash Premkumar]

Hi Waxiado, Chris and Tim,


when i compiled with :

> $ clang++ -g try.cpp `llvm-config --cppflags --ldflags --libs core jit
> native`-o3 -S -emit-llvm

I get  the following warnings

> clang: warning: -lz: 'linker' input unused

and when i compile the .s file with lli

i get

LLVM ERROR: Program used external function '_ZN4llvm16getGlobalContextEv'
> which could not be resolved!


Can you kindly help me resolve it?
