构建 Clang 时出错

Question

我正在尝试在 Linux（亚马逊的 EC2）上构建 Clang。我正在按照以下指南运行 make：

http://clang.llvm.org/get_started.html< /a>

我收到以下链接错误消息：

llvm[2]: Linking Debug+Asserts executable opt
/home/ec2-user/benchmark/build/tools/opt/Debug+Asserts/opt.o: In function `llvm::ParseIR(llvm::MemoryBuffer*, llvm::SMDiagnostic&, llvm::LLVMContext&)':

make[1]: *** [opt/.makeall] Error 2
make[1]: Leaving directory `/home/ec2-user/benchmark/build/tools'
make: *** [all] Error 1

有谁知道这意味着什么？

编辑：我从 svn 重建了整个项目，现在出现以下错误：

我遵循了这个，并且我能够在第一个镜头中成功构建它。

我猜您遇到了 C++ 标准库标头 的问题。因此，您需要按照上述链接中的步骤#6进行操作！

开始全新构建，并请确保满足此先决条件。
