Hi Kamil,

thank you for reporting the issue and the patch! I'll clone the bug for RHEL 8 and investigate if the issue is there too. (plus I'll fix it in Fedora too, for future RHEL releases).

Comment 2 Zdenek Dohnal 2019-01-03 09:45:15 UTC

would you mind attaching repo files, which needs to be enabled to install clang? Default repos in rhel7 image do not have clang.

Comment 3 Kamil Dudka 2019-01-03 10:28:14 UTC
clang can be installed from EPEL-7, for example:

# yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
# yum install clang
