Re: clang and Scientific Linux
--047d7bd9006e956b96051cfc958d Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable I have installed Scientific Linux. I would like to use clang. I see that clang is not part of the yum repository. I downloaded the latest Fedora zip from clang.llvm.org and installed clang in /usr/local When I go to run clang I get an error that GLIBCXX 3.4.20 is not available. I have found in libstdc++ =E2=80=8BGLIBCXX =E2=80=8B 3.4 to 3.4.19, but not GLIBCXX 3.4.20 =E2=80=8B.=E2=80=8B My version of gcc installed is 4.8.3 9.3l7 =E2=80=8B. I have looked for solutions on the web and many are partial or requiring complete source build of clang. I might be able to use a previous version or so of clang to that version that wants to use GLIBCXX 3.4.19 or less, but since clang was not installed via yum, I'm not certain how to download grade it properly. Are there any recommendations from this list on how to (uninstall/re-install) install clang on Scientific Linux? I understand that Scientific Linux is a variant of Fedora. Many of the tasks recommended for Fedora apply to Scientific Linux, but I'm still lost as my administration skills are being tasked. Thanks for the help and education.

The '--enablerepo' option should not be necessary. Also, EPEL cannot be considered a production reliable repository. Too many packages appear and disappear without warning to not make a local replica of old contents.
Re: clang and Scientific Linux
Nico, Connie - Thank you for the pointers to EPEL. I will continue with a source build of clang, but I will review the packages available at EPEL.
