我尝试构建LLVM和Clang，但遇到此错误:

最佳答案

您必须遵循http://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary。请注意您必须安装的软件依赖项。另外，再次检查是否设置了--prefix = directory。如果无法通过LLVM安装Clang(成功安装LLVM之后)，则可以尝试使用apt-get install clang和clang++进行安装。因此，您可以使用此clang编译LLVM传递。对于其他相应的软件包，例如VMkit for Java，您必须安装ant和oracle jdk。
