Answer 1

Take a look at this post: https://github.com/foniod/redbpf/issues/89

They install llvm-toolset-7-clang with the following commands:

sudo yum -y install http://mirror.centos.org/centos/7/extras/x86_64/Packages/centos-release-scl-rh-2-3.el7.centos.noarch.rpm
sudo yum -y install http://mirror.centos.org/centos/7/extras/x86_64/Packages/centos-release-scl-2-3.el7.centos.noarch.rpm
sudo yum -y install http://mirror.centos.org/centos/7/sclo/x86_64/rh/Packages/l/llvm-toolset-7-clang-4.0.1-1.el7.x86_64.rpm
sudo yum install -y llvm-toolset-7-clang

You can download the files from here:

centos-sclo-rh - REPO

I know that you can't use yum but I just wanetd to mention which Repo you can use.

I used a download only for it and it has a lot of dependencies:

devtoolset-7-binutils
devtoolset-7-gcc
devtoolset-7-gcc-c++
devtoolset-7-libstdc++-devel
devtoolset-7-runtime
llvm-toolset-7-clang-libs
llvm-toolset-7-compiler-rt
llvm-toolset-7-libomp
llvm-toolset-7-llvm-libs
llvm-toolset-7-runtime

The urls to download one package would be:

http://mirror.cj2.nl/centos/7.8.2003/sclo/x86_64/rh/
