c++ - 无法构建 lldb - 找不到 'atomic' 文件

Question

我正在尝试构建 lldb，它是 Clang/LLVM 3.4.2 下载的一部分，地址为 LLVM Download Page .

我可以构建 LLVM、Clang、Compiler-RT 和 Extras。但是，当我将 LLDB 添加到我的配方时，构建失败:

根据 Building LLDB 的要求，LLDB 在 Clang 旁边被解压:

llvm
|
`-- tools
    |
    +-- clang
    |
    `-- lldb

LLDB 正在按要求在构建目录中构建(其他所有内容也是如此):

mkdir build
cd build
../llvm/configure --enable-optimized --prefix=/usr/local
make -j4

我在 LLDB @ Mac OSX: build on Snow Leopard (still) supported? 上发现了一个类似的问题。 .但是，建议的解决方案是从命令行使用 xcodebuild 转动一些旋钮。我没有使用 Xcode，所以它不是我的替代品。

我的环境是 OS X 10.8.5，x64，已完全修补。 Xcode 版本 5.1.1 (5B1008)。我在 usr/local/ 中安装了 Clang 3.4.2(没有 lldb)，但我不相信它被使用了。

如何从命令行构建 lldb？

在运行“配置”脚本时添加“--enable-cxx11”开关。

默认情况下，c++11 是禁用的。
