Hi, a new version of llvm toolset was released on RHEL including clang 5 several months ago: https://developers.redhat.com/blog/2018/05/03/announcing-ga-for-latest-software-collections-developer-toolset-compilers/ devtoolset 7.1 (gcc 7.3) was announced around the same time and has been in CentOS sclo repo for some time now, but still no sign of clang 5. Is this on anyone's to do list? llvm toolset contains a really convenient version of clang / clang-format, which I believe many developers are using daily for various tools. Clang 5 is required for C++17 support, so a prompt update would be highly appreciated. Sorry if this is not the correct mailing list. Best regards Tim
