如何在 Ubuntu 18.04 上安装 clang-14？

Question

你能帮我在 Ubuntu 18.04 上安装 clang-14 吗？我认为我需要一个有效的存储库，因为 apt-get install clang-14 不起作用。

$ cat /etc/issue

Answer 1

您可以按照 llvm 页面上的说明下载 clang 14：

wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh 14

Answer 2

clang-14不适用于您的版本...但从Ubuntu 22.04 起可用

因此，您可能需要考虑升级到 22.04。
