无法构建 lldb - 找不到"原子"文件

Cannot build lldb - 'atomic' file not found

本文关键字：原子 文件 找不到 构建 lldb      更新时间：2023-10-16

我正在尝试构建lldb，这是Clang/LLVM的3.4.2下载的一部分在LLVM下载页面

我可以构建LLVM, Clang, Compiler-RT和其他工具。然而，当我将LLDB添加到我的配方时，构建失败:

LLDB被解包在Clang旁边，根据要求，每个建筑LLDB:

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

LLDB正在按照请求在构建目录中构建(与其他所有内容一样):

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

我在LLDB @ Mac OSX上发现了一个类似的问题:在雪豹上构建(仍然)支持?但是，建议的解决方案是在命令行中使用xcodebuild进行一些操作。我不使用Xcode，所以它不是我的替代品。

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

如何从命令行构建lldb ?

在运行"configure"脚本时添加"——enable-cxx11"开关。

c++11默认禁用

更多信息运行"configure——help"

必须同时使用——enable-libcpp——enable-cxx11来配置包含lldb的llvm构建。但是，如果您尝试使用3.4进行构建，则会遇到另一个问题。

未定义符号SystemRuntimeMacOSX::Initialize和SystemRuntimeMacOSX::Terminate
