Question

我正在使用Ubuntu 13.10 64位操作系统。我已经下载并使用make构建了LLVM 3.4。编译器：gcc 4.8.1 Shell：zsh

在配置过程中，使用了默认前缀/usr/local/。我没有使用任何其他自定义选项。

源代码和构建位于我的主文件夹中：

~/llvm_workdir/build
~/llvm_workdir/llvm

当我尝试First Function tutorial时，我面临一系列问题。第一个问题与它们在源树中进行了一些更改这一事实有关。他们在IR目录中移动了一些头文件（例如Function.h）。（该教程适用于llvm的2.4版本。）我更正了教程源代码文件中的包含，并且出现了新的错误。第一类是这样的：

1]
zsh: command not found: llvm-config : I'm using the `zsh shell`, which is compatible with bash.

return N >= 64 || (-(INT64_C(1)<<(N-1)) <= x && x < (INT64_C(1)<<(N-1)));**

第二类与内部某些方法中的签名更改有关：

tut1_first_function.cpp:44:26: note: candidate is:
In file included from /usr/include/llvm/IR/GlobalValue.h:22:0,
from /usr/include/llvm/IR/Function.h:25,

                       ^
/usr/include/llvm/IR/DerivedTypes.h:58:23: note:   candidate expects 2 arguments, 1 provided**

我不知道要传入的其他参数是什么。我是LLVM的新手，我现在开始学习它。我还没有发现任何与新LLVM版本相对应的新教程。

如何解决上述问题？有解决方法吗？

LLVM正在积极开发中。尝试将编写到2.4版本的教程 - 超过5年 - 应用到最新版本将是一个令人沮丧的教训。

The Kaleidoscope tutorial是最新版本，通常会在新版本中保持这种状态，因此我建议您使用它。特别是，lesson 3看起来涵盖了您链接的网页中的主题。
