CloudLinux 7.8 error installing postgresql 11 Requires: llvm-toolset-7-clang >= 4.0.1

Question

I've got a CloudLinux 7.8 (based on CentOS 7) machine and I'm trying to install postgresql11-devel onto the system and it fails due to 'llvm-toolset-7-clang >= 4.0.1'.

Here is the full error

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I've tried installing the latest llvm-toolset-6.0 but it cannot find it.

Update

Tried just installing the libpqxx-devel package but get the same error

Update

Unfortunately this machine has CPanel on it, which could be getting in the way.

Adding the centos SCL doesn't work, but maybe there is something similar for cloudlinux, but I don't know what it is.

Answer 1

Like Rishitha Minol said, but specific to CentOS:

yum install centos-release-scl-rh

then update or install as needed.
