使用cmake从llvm源目录开发llvm传递 | 使用cmake从llvm源目录开发llvm传递

本文介绍了使用cmake从llvm源目录开发llvm传递的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试图在我的项目目录下开发一个llvm pass。为此，我遵循。我在这个链接中适当地创建我的CMakeFiles，我的最终项目目录是：

  |  -  src 
 | |  -  CMakeLists.txt 
 | |  -  bigForPass 
 | | |  -  CMakeLists.txt 
 | | |  -  bigForPass.cpp 
 | | |  -  merged.bc 
 | |  -  build

我还将我的源文件与llvm根目录链接，没有任何问题。
最后，我在'build'文件夹下构建，我的共享库成功创建，没有问题（在build / bin文件夹下），名称为LLVMHello1.dylib。
然而，当我尝试使用命令运行我的通过merged.bc文件（其中包含我的llvm代码）

  opt -load ../build/bin/LLVMHello1.dylib -bishe_insert< merged.bc> final.bc

我一直收到错误;

 打开'../build/bin/LLVMHello1.dylib'时出错：dlopen（../ build / bin / LLVMHello1.dylib，9）：未找到符号：__ZTIN4llvm10ModulePassE 
引用自：../build/bin/LLVMHello1.dylib 
预期在：flat命名空间
在../build/bin/LLVMHello1.dylib 
中 - 请求被忽略。有任何想法和建议对此赞赏吗？

  SET（CMAKE_CXX_FLAGS-Wall -fno-rtti）到我的传递图书馆的CMakeLists.txt，然后它的工作。
 
I am trying to develop an llvm pass under my project directory. For that, I follow the info in http://llvm.org/docs/CMake.html#developing-llvm-pass-out-of-source. I create my CMakeFiles appropriately as in this link and my final project directory is like;
|-- src
|   |-- CMakeLists.txt
|   |-- bigForPass
|   |   |-- CMakeLists.txt
|   |   |-- bigForPass.cpp
|   |   |-- merged.bc
|   |-- build
I also linked my source files with llvm root directory without any problem.Finally I make the build under the 'build' folder and my shared library is created successfully with no problems (under build/bin folder) with the name LLVMHello1.dylib.However, when I try to run my pass over merged.bc file (which contains my llvm code) with the command
opt -load ../build/bin/LLVMHello1.dylib -bishe_insert <merged.bc> final.bc
I keep getting the error;
Error opening '../build/bin/LLVMHello1.dylib': dlopen(../build/bin/LLVMHello1.dylib, 9): Symbol not found: __ZTIN4llvm10ModulePassE
  Referenced from: ../build/bin/LLVMHello1.dylib
  Expected in: flat namespace
 in ../build/bin/LLVMHello1.dylib
  -load request ignored.
Any ideas and suggestions on this appreciated ?
Thanks a lot in advance.

So I added SET(CMAKE_CXX_FLAGS "-Wall -fno-rtti") to CMakeLists.txt of my pass library and then it's working.
