So I have a docker with CentOS 7 which has installed bazel. I've installed devtoolset-8, llvm-toolset-7.0 and centos-release-scl. I've also installed bazel 0.29.1 and made.

export CC=clang
export CXX=clang++

I have an shell script which run basel. Befor bazel build command in top of the script I have

source /opt/rh/llvm-toolset-7.0/enable

which enables LLVM-7.0/Clang-7.0. But build failes with:

/opt/rh/llvm-toolset-7.0/root/usr/bin/clang: error while loading shared libraries: libLLVM-7.so: cannot open shared object file: No such file or directory

But this lib exists! It's in /opt/rh/llvm-toolset-7.0/root/usr/lib64/

May someone pls help with this ?
