如何用llvm和g ++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，我得到它们在/usr/bin。一些链接的二进制文件被破坏（llvm-gcc,llvm-g++,llvm-cpp等）。包含文件位于/usr/include/llvm之内，库位在/usr/lib/llvm之内。如何使用g++编译它们？我试图按照指示编译tutorial中给出的万花筒代码，但它无法编译。

我得到这个：

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 

我找不到LLVMContext.h文件了。所以我想这可能是一个版本问题。 我该怎么做才能使它工作？

有些帮助会很好！在此先感谢... :)

Answer 1

看起来像标题未安装或安装在您不使用的路径。我的建议是从llvm.org网站或svn下载代码，并使用它来构建万花筒示例。这很简单，所有代码都在示例目录中。

不要使用yum，请按照this或this链接安装clang/llvm。
