apache+php 64 calling elf32 exe
by Riccardo Ghiglianovich 17 Oct '05

17 Oct '05

Hi all, I am new here; I have found that if I call an ELF32 Executable program from a php page loaded by a 64 bit PHP module then I obtain a shared library error, even if the program does not require the library. practical example: compile this ====== pro.c #include <stdio.h> main() { printf("Hello world\n"); } ------ cc -o pro -m32 pro.c then call it from a php page: ========= r.phtml <?php $s = "/tmp/pro 2>/tmp/er 1>&2"; echo "$s : "; $rrr=exec($s); echo `cat /tmp/er`; echo "<hr>"; // just to test that it works... $s = "ls -al /tmp 2>/tmp/er 1>&2"; echo "$s : "; $rrr=exec($s); echo `cat /tmp/er`; ?> ---- http://localhost/r,phtml issuee? Error?Bug? my fault??? Hints? I cannot recompile at 64 all my programs ... Thanks, regards, Ric

SK8N SUSE 9.3 problems
by Marcin Zalewski 12 Sep '05

12 Sep '05

Hello, I am trying to install SUSE 9.3 on Asus SK8N motherboard running Opteron. I use the built-in Promise SATA controller with two disks in IDE mode. I was able to perfectly run SuSE 9.1 on this system for a long, long time. Now, with SuSE 9.3 I am not even able to get through the installation. It seems that the disk access causes the installation to hang sooner or later. When files are being copied the installation just freezes. It seems that this problem is not specific to SUSE. Any other distro with 2.6 kernel that I tried freezes in the same way as SUSE. Does anyone have a success story installing SUSE 9.3 on a similar setup? And also, is there some way that I can save kernel messages during installation? Thanks, Marcin Zalewski

xine on AMD64
by Alex 10 Aug '05

10 Aug '05

Hi I'm using SuSE professional 9.3 on a AMD64. To be able to watch DVD's, I compiled Xine from sources with the needed packages. Compiling xine-lib and xine-ui doesn't make any problems, but after launching xine, I have the foolowing error message: Cannot open display "*". Segmentation fault. After I changed the DISPLAY Variable to 127.0.0.1 and exported it, the first error message doesn't appear, but I get the segfault again. The interesting thing is that DVD's could be read in kaffeine without problems, so I think the problem is in xine-ui. Has anybody a hint?? Thanx Al

Howto build 32bit apps on amd64 suse 9.3?
by Fred van Zwieten 18 Jul '05

18 Jul '05

Hi all, I am trying to compile syncekonnector-0.2.1 on a suse 9.3 amd64 platform. It depends on synce and synce-devel packages with are both (to my knowledge 32bit packages. configure complains about de synce libraries not being compatible in config.log. So, I instructed configure to use 32bit compile (-m32). Now, it complains it can't find libXext, but I know it's there (devel packages are both in 64bit and 32bit present). I'm not a devel guy, who to get out of this mess?

Puzzling wild variation of execution time
by Sheo Shanker Prasad 01 Jul '05

01 Jul '05

I will greatly appreciate help in understanding the puzzling wild variation in the execution time of small test/benchmark program, as explained below. (1) The nature of the benchmark/test program: A floating point arithmetic intensive atmospheric chemistry modeling task. It used to take, in a consistent manner, around 2m 37s on my machine when it was running under SuSe 9.1 Pro. When I run the benchmark program, I shut-off all other programs. Thus, during its run, it is the only active program. THe rest are belonging to root are sleeping. There is no other user. (2) The machine: Dual Opteron 250 with 4 GB of PC3200 (DDR) memory in 4 dimms that fill two dimms on cpu0 and two dimms on cpu1 installed in Tyan Thunder K8 system board that has American MegaTrend AMIBIOS V2-04. It now runs under SuSE 9.3 Pro and the Linux version 2.6.11.4-21.7-smp (geeko@buildhost) (gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)) #1 SMP Thu Jun 2 14:23:14 UTC 2005 (3) Background of the problem: After only 4 months of the delivery of the machine by the vendor, the mother board failed. The machine was sent to the vendor. He then replaced the mother board with a new one and installed SuSE 9.3 Pro to bring the machine up-to-date with the Linux version 2.6.11.4-21.7-smp (geeko@buildhost) (gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)) #1 SMP Thu Jun 2 14:23:14 UTC 2005 (4) The problem: After the repair and upgrade to 9.3 Pro, the execution times of the same test/benchmark program varies widely between run to run. It is never consistent. It varies from 2m 37s to more than 6m. A pattern is seen in the variation. Usually, the longest execution time is when the machine is started after remaining shut-off for a few hours. The shortest execution time is obtained after the machine has been constantly on for abot 7 to 10 hours. (5) My puzzle: While a computer is well known to be reproducible, the wild variation by a factor of almost 3 in the execution is very disturbing. What could be the cause? Does it mean that some vital component involved in execution of the numerical modeling (RAM memory or the memory on the CPUs) are loose or erratic and may be about to go bad? I am just puzzled. Any clue from you all will be really very very much appreciated. -- Best regards. Sheo (Sheo S.

RE: [suse-amd64] Puzzling wild variation of execution time
by Black, Alain 30 Jun '05

It sounds more like why when benchmarks are run, they are run 3 or more times with the first run being thrown out. This is due to the initial loading of data (reading files off of disk into cache) that must be done. The next run will not have as much disk I/O and if the test is small enough, could actually be reading straight from memory, which is significantly faster than disk. After a reboot, or being powered off, the cache is clear, so all data needs to be read into memory again. -Alain. -----Original Message----- From: fabrice piccini [mailto:fpiccini@nerim.net] Sent: Thursday, June 30, 2005 12:15 PM To: suse-amd64(a)suse.com Subject: Re: [suse-amd64] Puzzling wild variation of execution time Sheo Shanker Prasad wrote: > I will greatly appreciate help in understanding the puzzling wild variation in > the execution time of small test/benchmark program, as explained below. > > (1) The nature of the benchmark/test program: > > A floating point arithmetic intensive atmospheric chemistry modeling task.

Ah, I've just reread your post. You said the longest time is after the machine is started after a long shut-off... What occurs if, after a long period of uptime you reboot the machine and immediately run your algorithm ? - If you get the same good results (2'37") then you certainly have a hardware problem (thermal stabilization problem on some component ?) - If you get bad results (longest time) then it's certainly a software related problem (bios/kernel/compiler) sorry not to be able to help you more...that was only to start the discussion...now it's time for true experts. cheers, fabrice -- Check the List-Unsubscribe header to unsubscribe For additional commands, email: suse-amd64-help(a)suse.com

nvidia and no 3D after driver upgrade
by Dima 29 Jun '05

29 Jun '05

Hi, after upgrading nvidia driver from v.1.0-7174 to 1.0-7667 3D stopped working. glxgears run at 15 fps and none of GL screensavers start. I cabn see that "nvidia" module is loaded, "glxinfo" says that direct rendering enabled and correctly identifies the video card and the driver. Also , sax2 says that 3D enabled. Originally, nvidia driver was installed through YOU. The upgrade was done first running "nvidia-installer --uninstall" and after that running Nvidia's installer (NVIDIA-Linux-x86_64-1.0-7667-pkg2.run) since YOU did not fetch any new drivers. Looking at the nvidia-installer log I have not spotted errors, it says that "installed succesfully". What could be the problem? Any advise will be appreciated. Dima. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Ugly fonts in 32 bit apps in Suse 9.2 Pro
by Suleyman Karabuk 28 Jun '05

28 Jun '05

Hi, I installed Suse 9.2 Pro 64 bit version and as expected the fonts looked horrible. Then I followed the usual drill: (1) installed freetype2 srpms, enabled bytecode interpreter, rebuild the rpm and reinstalled it, (2) installed Microsoft true type fonts via Yast online update. Everything went fine, I have gorgeous fonts that rival even MS Windows which I see at some people's PCs. However, when I call a 32bit application eg Eclipse, Thunderbird 32bit etc ugliness comes back. But only with the 32 bit applications. The 64 bits applics are always fine. I looked into the freetype2 srpm searching for a clue as to how to uptade 32bit freetype2 libs with bytecode enabled to no success. As a last resort I downloaded freetype2 sources, enabled bytecode and compiled it on a 32bit machine. Then I copied the directory and installed the binaries on my 64 bit Suse thereby updating the 32bit freetype2 libs under /usr/lib. However, this was not successful. But to my surprise it did not screw up anything either. Any suggestions would be greatly appreciated. ____________________________________________________ Yahoo! Sports Rekindle the Rivalries.

RE: [suse-amd64] wmv files and MPlayer/Xine
by Black, Alain 27 Jun '05

Have you installed the w32codecs? I don't recall if wmv is part of them or not, try either xine's home page or packman.links2linux.org for the windows 32 codecs. -----Original Message----- From: Constantine 'Gus' Fantanas [mailto:fantanas@innocent.com] Sent: Friday, June 24, 2005 4:57 PM To: suse-amd64(a)suse.com Subject: [suse-amd64] wmv files and MPlayer/Xine Hi all. Can MPlayer and/or Xine play wmv files in SuSE 9.3? When I try to play a wmv file with MPlayer, I hear only audio and get the following errors: -----------------SNIP---------------- Requested video codec family [wmv9dmo] (vfm=dmo) not available. Enable it at compilation. Requested video codec family [wmvdmo] (vfm=dmo) not available. Enable it at compilation. Cannot find codec matching selected -vo and video format 0x33564D57. Read DOCS/HTML/en/codecs.html! ----------------SNIP------------------ The reason I decided to post this question was that I did read 'DOCS/HTML/en/codecs.html', but I did not see anything about wmv files. I perused MPlayer's codecs URL, but I did not see anything there either. I tried different '-vo ' (video output) options, but to no avail (which is understandable if the problem is the codec). Trying to play the same file with kaffeine (xine-based), I get similar behavior: the audio plays fine, but no video. What did I do wrong? I have an nVidia GeForce 440 To Go 64M card (on a Compaq Presario R3000Z-series AMD64-based laptop, which I bought specifically because it had an nVidia card and was 64-bit) . I compiled MPlayer from source because I could not get the rpms from the apt-get repositories to work right. (Other files, like MPEG, play fine, so I am definitely missing a codec.) If I run './configure --help', I do not see anything referring to the missing codec(s) --or did I miss the obvious? TIA for any help.
