Не удалось скомпилировать передачу в DLL на Windows

/ 02 февраля 2020

Я следую за https://www.cs.cornell.edu/~asampson/blog/llvm.html и пытаюсь скомпилировать передачу на Windows. Но когда я создаю проход с помощью Clion, он завершается ошибкой с

Но я добавляю и включаю каталог llvm в CMakeLists.

Дерево моего проекта: 

MySkeletonPass
├── CMakeLists.txt
└── skeleton
    ├── CMakeLists.txt
    └── Skeleton.cpp

внешний CMakeLists.txt - 

cmake_minimum_required(VERSION 3.15)
project(Skeleton)

set(LLVM_HOME I:/llvm_research/build_llvm)
set(LLVM_DIR ${LLVM_HOME}/lib/cmake/llvm)

А внутренний CMakeLists.txt - 

add_library(SkeletonPass MODULE
        # List your source files here.
        Skeleton.cpp
        )

# Use C++11 to compile your pass (i.e., supply -std=c++11).
target_compile_features(SkeletonPass PRIVATE cxx_range_for cxx_auto_type)

# LLVM is (typically) built with no C++ RTTI. We need to match that;
# otherwise, we'll get linker errors about missing RTTI data.
set_target_properties(SkeletonPass PROPERTIES
        COMPILE_FLAGS "-fno-rtti"
        )

скелет. cpp просто как 

#include "llvm/Pass.h"
#include "llvm/IR/Function.h"
#include "llvm/Support/raw_ostream.h"
#include "llvm/IR/LegacyPassManager.h"
#include "llvm/Transforms/IPO/PassManagerBuilder.h"
using namespace llvm;

namespace {
  struct SkeletonPass : public FunctionPass {
    static char ID;
    SkeletonPass() : FunctionPass(ID) {}

    virtual bool runOnFunction(Function &F) {
      llvm::errs() << "I saw a function called " << F.getName() << "!\n";
      return false;
    }
  };
}

char SkeletonPass::ID = 0;

// Automatically enable the pass.
// http://adriansampson.net/blog/clangpass.html
static void registerSkeletonPass(const PassManagerBuilder &,
                         legacy::PassManagerBase &PM) {
  PM.add(new SkeletonPass());
}
static RegisterStandardPasses
  RegisterMyPass(PassManagerBuilder::EP_EarlyAsPossible,
                 registerSkeletonPass);

Мне было интересно, почему он не может найти ссылку при сборке.

Более того, я создаю решение Clang и Library с VS2017 для build_llvm dir. Интересно, достаточно ли этого для построения прохода

против решения
