c++ - 如何使用 llvm 和 g++ 进行编译？

Question

我使用的是 fedora-11 系统，最近我安装了 llvm ( sudo yum -y install llvm llvm-docs llvm-devel )。当我搜索 llvm 时，我在 /usr/bin 中找到它们。某些指向二进制文件的链接已损坏(llvm-gcc、llvm-g++、llvm-cpp 等)。包含文件位于 /usr/include/llvm 中，库位于 /usr/lib/llvm 中。如何使用g++编译它们？我试图编译 tutorial 中给出的万花筒代码按照指示，但无法编译。

我明白了:

toy.cpp:5:30: error: llvm/LLVMContext.h: No such file or directory

toy.cpp:352: error: ‘getGlobalContext’ was not declared in this scope

toy.cpp: In member function ‘virtual llvm::Value* NumberExprAST::Codegen()’:

toy.cpp:358: error: ‘getGlobalContext’ was not declared in this scope

toy.cpp: In member function ‘virtual llvm::Value* BinaryExprAST::Codegen()’:

toy.cpp:379: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’

toy.cpp:379: error: ‘getGlobalContext’ was not declared in this scope

toy.cpp: In member function ‘llvm::Function* PrototypeAST::Codegen()’:

toy.cpp:407: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’

toy.cpp:407: error: ‘getGlobalContext’ was not declared in this scope

toy.cpp:408: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’

toy.cpp: In member function ‘llvm::Function* FunctionAST::Codegen()’:

toy.cpp:454: error: ‘getGlobalContext’ was not declared in this scope

toy.cpp: In function ‘int main()’:

toy.cpp:543: error: ‘LLVMContext’ was not declared in this scope

toy.cpp:543: error: ‘Context’ was not declared in this scope

toy.cpp:543: error: ‘getGlobalContext’ was not declared in this scope

我也找不到 LLVMContext.h 文件。所以我猜这可能是版本问题。我应该怎么做才能让它发挥作用？

一些帮助会很好!提前致谢...:)

看起来 header 未安装或安装在您未使用的路径中。我的建议是从 llvm.org 网站或 svn 下载代码并使用它来构建 Kaleidoscope 示例。它相当简单，所有代码都在示例目录中。
