如何在ubuntu12.04中编译llvm的compiler-rt（compiler-rt.llvm.org）？

当我编译compiler-rt时，我得到错误：

Answer 1

compiler_rt旨在在LLVM源代码树中编译。 This page详细说明了如何使用llvm，clang和compiler-rt创建此树，编译和测试所有内容。应该像Ubunbu上的魅力一样。

专业提示：使用CMake + Ninja构建整个内容要快得多。请参阅instructions here。

Answer 2

我使用

为i386和x64编译了编译器-rt

制作clang_linux

使用

检查可用平台
