SCLO: Clang 5 package
by Tim R 25 Jul '18

25 Jul '18

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-soft… 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

Mail has quit working
by TE Dukes 24 Jul '18

24 Jul '18

Hello, Mail has come to an abrupt stop. Running C7, postfix and dovecot. Using Roundcube as the client. Mail stopped working Saturday and I cannot figure was has happened. I have not touched this server except to upgrade packages. I believe Roundcube was updated maybe a week ago but know I was getting mail since then. Crond is no longer send mail. I checked /var/spool/mail as well as /Maildir in home directories. Zero byte files. Checked all logs and the only thing I could find was in /var/log/maillog : warning hostname localhost does not resolve to address 127.0.0.1 I corrected that by changing inet_interfaces to localhost from all in postfix.cf When I try to log in with Roundcube, it just times out. I'm stuck! TIA for any suggestions!!

FF60 does not allow download to ssh/davs
by johan.vermeulen7＠telenet.be 23 Jul '18

23 Jul '18

Hello All, this concerns fully updated Centos7 / Mate machines; I have people connect to ssh en davs locations. In /home/user/.gtk-bookmarks I put entries like ssh://192.168.1.8/data data-remote People can then click on the bookmark in the file manager and connect to it. Since FF60 people can no longer save files for instance from their mailbox to these "mounted" locations. Before, when choosing "save as", the mounted ssh location would appear in the download window. I guess this is not a bug but something one can disable/enable in about:config. Many thanks for any advise on this. greetings, J.

bad text under KDE and C7
by Michael Hennebry 23 Jul '18

23 Jul '18

I recently installed C7 from a C7+gnome CD. Gnome was awful enough that I promptly installed KDE. KDE is not doing so well either. Text in text editors invoked by "opening" a file is flakey at best. E.g. pieces disappear and duplicate. Terminals seem ok, including vim invoked from the terminal. Firefox text seems ok. The sidebar text in file-browser windows often has "black tape" over it, usually completely covering text. The file names are ok. Suggestions on how to dignose this? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

CentOS 7 + MATE : Folder contents not refreshed in file manager
by Nicolas Kovacs 21 Jul '18

21 Jul '18

Hi, I just migrated my workstation running CentOS 7 from KDE to MATE. It looks like I'm having the same problem with the Caja file manager than with Dolphin. Folder contents don't get refreshed automatically, and I have to hit F5. For example, when I download a file (say, a compressed archive) from the Internet, I have to hit F5 to see the file in Caja. And when I extract the archive, I have to hit F5 again. Anybody knows where this nagging problem comes from?

odd popups
by Fred Smith 21 Jul '18

21 Jul '18

Occasionally and without any action on my part, I get a popup saying I need to authenticate in order to read others' actions. I have no clue what this is for, so I always reject them. Anyone got a clue?
