<div>Hi,<br>
<br>
I am completely new to LLVM and to begin with, I am writing a basic pass(the Hello World Pass).<br>
I am trying to compile Hello.cpp using clang++ using the following command:<br>
<br>
> <i>clang -S -emit-llvm -I/home/lera/llvm/include Hello.cpp -o Hello.bc</i><br>
<br>
and get the following errors: <br>
<br>
