我正在使用LLVM conan package来构建我的编译器，到目前为止，它运行得很好，直到我尝试使用llvm::sys::getDefaultTargetTriple和llvm::TargetRegistry::lookupTarget。我得到了对两者的未定义引用。两者似乎都来自LLVM支持库，并且至少llvm::sys::getDefaultTargetTriple看起来是自动生成的（我在系统上找到了它的.inc源代码）。Conan似乎告诉CMake在LLVM支持库中进行链接，因为我可以看到，当我尝试构建并获得错误时，它被传递到链接器（例如）-lLLVMSupport。我看到一些人在过去切换到带有LLVM 3/4的GCC 5时遇到了链接器错误。但这是LLVM-13.0.0和gcc-12.0.1。柯南我看到了warns about C++ ABI compatibility with GCC-5
我改变了我的个人资料的设置，但没有改变（还）。我可能会尝试重建LLVM和更新这篇文章。
我真的需要在几个小时内拿到这个，是吗
1.一种手工知道我的操作系统的三元组字符串应该是什么的方法？我在这里看到了格式。它似乎是基于宏的？gcc -dumpmachine足够吗？
1.用这个手工生成一个“目标”有多可行，我正在对此进行逆向工程
1.主要问题是，如何修复此错误并链接到llvm::sys::getDefaultTargetTriple和llvm::TargetRegistry::lookupTarget
下面是完整的日志：
