llvm dev - May 2018 - About Error: Interpreter has not been linked in

Hello,

When I try to create execution engine I do get "*Interpreter has not been
linked in.*" error and EngineBuilder returns NULL.

Here is the line I use to create execution engine:

auto executionEngine
llvm::EngineBuilder(std::move(m_module)).setErrorStr(&error).create();

Here are all headers I have included:

#include "llvm/ADT/STLExtras.h"
#include "llvm/ExecutionEngine/ExecutionEngine.h"
#include "llvm/ExecutionEngine/GenericValue.h"
#include "llvm/IR/Argument.h"
#include "llvm/IR/BasicBlock.h"
#include "llvm/IR/Constants.h"
#include "llvm/IR/DerivedTypes.h"
#include "llvm/IR/Function.h"
#include "llvm/IR/IRBuilder.h"
#include "llvm/IR/Instructions.h"
#include "llvm/IR/LLVMContext.h"
#include "llvm/IR/Module.h"
#include "llvm/IR/Type.h"
#include "llvm/IR/Verifier.h"
#include "llvm/Support/Casting.h"
#include "llvm/Support/ManagedStatic.h"
#include "llvm/Support/TargetSelect.h"
#include "llvm/Support/raw_ostream.h"


And here is the simple IR code that I'm trying to JIT compile and execute
in memory:

; ModuleID = 'Program'
source_filename = "Program"

define i32 @fib(i32) {
entry:
  %i = alloca i32
  store i32 %0, i32* %i
  ret i32* %i
}


Could someone please tell the reason and how I can resolve this?

Thanks for helping!

Best,

Aaron

Ok. I figured out. Following methods needs to be called. That fixed the
issue.

llvm::InitializeNativeTarget();
LLVMInitializeNativeAsmPrinter();
LLVMInitializeNativeAsmParser();
LLVMLinkInMCJIT();

I believe the correct way is actually include the Interpreter’s header and the
rest is handled automatically. Should be similar for MCJIT
