“安装-y clang-9 libc++-9 dev libc++abi-9 dev”错误

Question

我安装了Mistuba2软件包(https://github.com/mitsuba-renderer/mitsuba2)，以便能够运行btf-呈现(https://github.com/elerac/btf-rendering/)。

然而，要安装三菱，就必须使用clang9和其他一些过时的软件包。在尝试安装这些包时，linux会给我一条我无法解决的错误消息，但我怀疑有必要降低系统的级别。

要执行的命令：

sudo apt安装-y clang-9 libc++-9 dev libc++abi-9-dev

并生成以下错误：

vitor-avancini@Nabucodonosor-desk:~$ sudo apt install -y clang-9 libc++-9-dev libc++abi-9-dev cmake ninja-build

如何解决这个问题？

Answer 1

clang安装说明已经过时；您应该运行以下命令：

sudo apt install -y clang libc++-dev libc++abi-dev cmake ninja-build

要构建三菱2，请遵循指示，但请使用

export CC=clang
export CXX=clang++

而不是直接引用clang-9和clang++-9。

您似乎已经在配置中添加了18.04存储库，如果是这样的话，您应该删除它们。
