Re: [CentOS] GCC 4.9 in CentOS 7 ??
Hello guys.. or you dig it up by hand and use environment-modules In our cluster I prepaired my self to do it step by step, because we need the binary as rpm (because of dependency) to pull it onto the cluster nodes, but this takes a lot of time.

[CentOS] install of audacity kills audio
# uname -r 3.10.0-514.6.1.el7.x86_64 # cat /etc/centos-release CentOS Linux release 7.3.1611 (Core) Prior to the below the sound/audio on my system worked just fine. Then a yum of install of audacity with dependencies: ... Downloading packages: (1/6): vamp-plugin-sdk-2.5-4.el7.x86_64.rpm| 172 kB 00:03 (2/6): wxGTK-2.8.12-20.el7.x86_64.rpm | 2.9 MB 00:00 (3/6): audacity-2.1.1-1.el7.x86_64.rpm | 4.3 MB 00:08 (4/6): portaudio-19-16.el7.x86_64.rpm | 88 kB 00:09 (5/6): libid3tag-0.15.1b-17.el7.x86_64.rpm | 48 kB 00:09 (6/6): wxBase-2.8.12-20.el7.x86_64.rpm | 588 kB 00:10 ... Now nothing which is supposed to output is working; e.g., something as simple as "play file.wav" hangs at the start and outputs no sound at all. Two minutes prior to the install the exact same command worked. Same story with other apps using sound. I "erased" (rpm -e ...) all of the installed packages listed above. That didn''t fix the problem. My guess is that the install loaded one or more bogus kernel modules, it would be nice if lsmod showed WHEN the modules were loaded, but it doesn't.

[CentOS] Delaying services starting at boot
Back to the challenge of a server with no RTC. Chrony advances the clock some 14B sec a bit after bootup. So sometimes services like httpd start with a bad time of Dec 31, 1969. Is there some way to delay services starting until Chrony has done its job to bring the clock up? I think it matters to some extent, as /var/log/http/error.log is filled this time with messages about http starting with that 1969 date. Other times, on boot, I don't see these messages, and thus guess that Chrony set the time before httpd started. thanks ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 6, 8, mplayer, "vector smash protection is enabled"
This *just* started happening. Video works, but if I try to play streaming audio, I get nothing. In .xsession-errors, I see that message, along with others Object::connect: No such slot TaskManager::GroupManager::taskDestroyed(QObject*) ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused ###!!! [Parent][MessageChannel::Call] Error: (msgtype=0xAA0001,name=PPluginInstance::Msg___delete__) Channel error: cannot send/recv Based on a brief google, it *appears* as though vector smash protection is protecting me from playing music. Note that mplayer does play videos with no audio (i.e., from our surveillance cameras in our secure rooms). Can I turn it off, or is there something else blocking me? Let me note that flash-plugin works to play music... except, as I noted last week, it crashes every 15-20 minutes, so I was going to mplayer from the command line mark ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Even not knowing python, it's fairly obvious - it says you need Python
version 3.4 or greater for numpy 1.12.0, you've installed Python 3.3
Generally, I don't use pip for installing numpy - it's such a common
requirement for other packages that it's in the repositories. Try
something like
yum install python33-numpy
P.
Using "yum install python33-numpy " could be a solution for numpy but this just
forward the problem to the next package I have to install with pip. I do not
understand why a python 3.3 environment try to install incompatibles packages.
I tryed to install python34 with yum but it does not seem to work with scl
environment (yum install python34-setuptools python34)
