如何在同一台电脑(ubuntu)上同时安装多个版本的llvm libc++？

Question

我试过了显而易见的：

apt-get install -y clang++-7 libc++abi-7-dev libc++-7-dev
apt-get install -y clang++-8 libc++-8-dev libc++abi-8-dev
apt-get install -y clang++-9 libc++-9-dev libc++abi-9-dev
apt-get install -y clang++-10 libc++-10-dev libc++abi-10-dev

多个版本的clang++没有问题。但每个版本的libc++似乎都会卸载以前的版本。

当我尝试的时候：

apt-get install libc++abi-7-dev libc++-7-dev  libc++abi-8-dev libc++-8-dev libc++-9-dev libc++abi-9-dev libc++-10-dev libc++abi-10-dev

我得到了

The following packages have unmet dependencies:
 libc++-10-dev : Conflicts: libc++-x.y-dev
 libc++-7-dev : Depends: libc++1-7 (= 1:7.0.1-12) but it is not going to be installed

                Conflicts: libc++-x.y-dev

                Conflicts: libc++-x.y-dev

现在我正在Ubuntu 20.04上尝试这个，但我在以前版本的ubuntu上也尝试过类似的方法，基本上也遇到了同样的问题。

使用docker或虚拟机似乎是解决此问题的唯一实际解决方案。

您可以使用ubuntu:20.04基础镜像创建不同版本的构建镜像。要构建映像，请将不同的Dockefile创建为

Dockerfile.vX (用不同的版本号替换X)

FROM ubuntu:20.04

RUN apt-get install -y clang++-X libc++abi-X-dev libc++-X-dev

CMD ['/bin/bash']

然后构建版本X docker build -f Dockerfile.vX -t lewisP/lvvm:X .的映像

并作为containers docker run -it lewisP/lvvm:X运行它
