Compile error on CentOS 4.6

05 Jun '08

I am installing SPLASH(http://www-flash.stanford.edu/SPLASH/) benchmark codes on CentOS 4.6. And there is compile error during make.. Here is the error messages. Does it come from the gcc library? Should I update the gcc or other library?

Hello all, I just been wasting time with an Asus mobo trying to get CentOS/RHEL up and running for my home lab using Xen Technologies and need an advice in order to have a fully working Box, got any suggestions? which chipsets are the best out of the box for Centos AMD platform (AMD based, nVidia based, Ati Based)? (this could be a plus) I already have the AMD Athlon 64 X2 4800+ Processor AM2 Socket, 6Gb RAM to use(maybe more), a IBM Netserver xSeries 205 Case and a 250gb SATA HD. thanks in advance. Cheers.

mod_rewrite issue
by Gary 04 Jun '08

04 Jun '08

I'm installing Drupal 6.2 in the document root of a CentOS 5 install using httpd-2.2.3-11.el5_1. I'm using a virtual host entry with the following rewrite rule to enable "clean" URLs: RewriteRule ^(.*)$ index.php?q=$1 [R,L,QSA] This works fine expect the user still sees the "ugly" URL in the address bar. However, if I remove the R, it breaks completely. Any clues? I can send more of my httpd.conf if you think it'll help. much thanks, Gary

"invest" applet in centos 5.1 seems to be inoperative
by Charles Campbell 04 Jun '08

04 Jun '08

Hello! I figured it'd be interesting to see a miniature graph of the Dow Jones on my panel bar. Unfortunately, it doesn't appear to do anything, and the preferences for it isn't helpful (it already has DJIA). So, any suggestions on how to get it to work? Regards, Charles Campbell

try using autofs. ----- Original Message ---- From: James Pearson <james-p(a)moving-picture.com> To: centos(a)centos.org Sent: Wednesday, June 4, 2008 19:42:18 Subject: [CentOS] Mounting cifs shares by non-root users on CentOS 4.6 I'm trying to set up mounting of a Windows share for non-root users via /etc/fstab on a CentOS 4.6 box - I've followed the instructions at: <http://wiki.centos.org/TipsAndTricks/WindowsShares> Using something like the /etc/fstab example given in the wiki page (with, of course, using a valid share, username and password for my set up): //winbox/getme /mnt/win cifs user,uid=500,rw,suid,username=sushi,password=yummy 0 0 When as a non-root user I do: % mount /mnt/win mount error 1 = Operation not permitted Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) Running mount as root works fine, but I can not get it to work for non-root users. Any ideas?

INN Python support in Centos 5.1
by David Hláčik 04 Jun '08

04 Jun '08

Hello . i want to ask several questions : 1) Is INN on Centos5.1 compiled with python auth hooks support? 2) If i want my messages on news server to keep forever (history) , should i change expire.ctl? What i need to set 3) Is there some configuration which i need to set to be able to use python auth hooks? Or can i simple proceed with adding them to readers.conf ( I allready tested my nnrpd_auth.py with nnrpd.py, which is working (nnrpd module is imported ). Thanks in advance!
