构建llvm 3.0时出错

Question

我试图在我的机器上获得llvm 3.0,但是当我给make -k时,我得到以下错误.

chethan@ubuntu:~/llvm-3.0$ make
make[1]: Entering directory `/home/chethan/llvm-3.0/lib/Support'
llvm[1]: Compiling APFloat.cpp for Release build

我按照这些步骤在我的机器上构建llvm.

1. 从llvm下载页面获取llvm源zip文件并解压缩到文件夹llvm-3.0
2. cd /home/chethan/llvm-3.0
3. ./配置
4. 制作-k

虽然在这种情况下,我只是给了'make',以便在第一次出错时停止.我在我的机器上安装了llvm-gcc 4.2.

今天早上我在家用机器上执行了相同的步骤,并成功构建了llvm-3.0!知道这里可能缺少什么吗？

配置CC=gcc CXX=g++.看起来配置脚本正在查找一个版本的clang,它实际上没有正确设置来编译C++代码.
