未满足的依赖项 libc++

Question

我应该如何在我的 lubuntu 机器上正确安装 clang 的 c++ 库（使用 STL）？我想使用 clang 及其 c++ 库，因为它为即将到来的 c++14 标准提供了更好的支持。

尝试安装 libc++ 时：

sudo apt-get install libc++

我得到：

我在三星 Series 9 Ultrabook 上运行 lubuntu 14.04。我不明白这些冲突，尤其是那些与 CUDA 相关的冲突，它应该只适用于带有 NVidia GPU 的系统。

请让我知道我需要提供哪些其他信息。

编辑：

经过一番尝试，我安装了 libc++-dev 包：

sudo apt-get install libc++-dev

这安装了 clang 现在找到和使用的头文件。这并没有回答为什么 apt-get 试图安装显然不存在的 libc++ 以及为什么它会发生冲突（所有东西都是 CUDA！）的原始问题。

没有名为libc++. 它是libc++1。

所以运行命令：

sudo apt-get install libc++1 multiarch-support libc6 libc++-dev libc++-helpers libc++-test libc++abi-dev libc++abi-test libc++abi1
