[opensuse] c - Segmentation fault on 11.4 - need help figuring out (strtod?)
by David C. Rankin 05 Nov '11

05 Nov '11

Guys, Helping my son with a simple little area program, I am running into a segmentation fault after program execution. It seems to be with the strtod conversion, but I can't figure out why. It compiles without issue and executes fine, but then I get a Segmentation Fault error after the program ends. The code is: #include <stdio.h> #include <stdlib.h> #include <math.h> int main (int argc, char *argv[]) { if (argc < 2) { fprintf(stderr, "\nERROR: Usage: %s radius list\n", argv[0]); fprintf(stderr, "\n example: %s 4 16 21 8 for area calculations\n\n", argv[0]); exit (1); } char *p; int i; double rad; double area; for (i=1;i<=argc;i++) { rad = strtod(argv[i],&p); area = M_PI*rad*rad; printf(" rad : %5.2f area : %10.4f\n", rad, area); } return 0; } It compiles without error on 11.4 (x86_64) with: gcc -Wall ztst.c -o ztst It seems to run fine: 13:22 alchemy:~/dev/prg/ccpp/src-c/misc> ./ztst 1 2 3 4 rad : 1.00 area : 3.1416 rad : 2.00 area : 12.5664 rad : 3.00 area : 28.2743 rad : 4.00 area : 50.2655 Segmentation fault So where is this segfault coming from? I have experimented and commented out of the strtod function and just hard coded values for rad (i.e.: rad = (double) i;) and it runs without a segfault. Am I doing something wrong with the strtod call? What say the experts? -- David C.

[opensuse] Weird network issue
by Rich Coe 05 Nov '11

05 Nov '11

I have a 12.1 system which has one network interface wlan0 with an ipaddr of 192.168.1.8 and a default route of 192.168.1.1. For some unknown reason, when I try to connect to at least one particular ipaddr, the os tries to arp 172.16.1.2. I have no idea where it's getting this addr. It doesn't matter how many times I bring up & down the interface, the os persists in looking up this invalid host and thus any attempt to connect fails with host unreachable. Any ideas how I can get rid of this invalid addr and where it's coming from? The only thing that works clearing it is rebooting, which is very annoying.

[opensuse] Skype and obsolete setsockopt
by C. van Nidek 04 Nov '11

04 Nov '11

A message which I see already very long in dmesg is as follows: process `skype' is using obsolete setsockopt SO_BSDCOMPAT Have no problem running Skype but I find this information troubling. Is there something to use a nonobsolete setsockopt (whatever that is)? -- Linux User 183145 using LXDE and KDE4 on a Pentium IV , powered by openSUSE 11.4 (i586) Kernel: 3.1.0-3-desktop LXDE WM & KDE Development Platform: 4.7.2 (4.7.2) -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Downloading "Scientific American"
by Stan Goodman 04 Nov '11

04 Nov '11

I have been downloading this publication for years, and have never encountered difficulty doing so before the current issue. Suddenly, my system can't hold a connection long enough to d/l more than a few bytes. The publisher assures me that all is well at his end, and any problem must be with the ISP. He may well be right, since for quite a while I have been experiencing disconnects with certain web sites, notably CNN.COM. I cannot imagine why such a problem should involve only certain sites, but think the problem is likely to occur with large downloads from other servers as well. The obvious solution would seem to be to use Kget to manage the operation. I have integrated Kget with Konqueror and attempted the download. At that point, the small Kget screen (this is not the Kget screen containing the source URL and the file name, but a reduces one asking, as far as I remember, only for what to do with the file) disappeared, and I see no Net activity in the router LEDs. In other words, I have no clue what, if anything, Kget is doing or how much, if any, it has downloaded. Nor do I see anything way to make a decision (e.g. start again, give up, keep at it,...). I know that it is running, because bash tells me so when I try to start it again. I'd like some advice on what to do when Kget seems not to be doing anything, not reporting its condition, and not offering any way to control it. Any comments on how to try to correct the dropout problem will be greatly appreaciated. -- Stan Goodman Qiryat Tiv'on Israel -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] RPMs for BURG bootloader.
by Valerio Mariani 04 Nov '11

04 Nov '11

If anyone is interested, I created some rpms for BURG, that I use on OpenSUSE 12.1 RC2. You can find them in one of my Build Service projects, if you are interested: https://build.opensuse.org/project/show?project=home%3Avalmar73%3Aburg The packages just install the binary files required to use BURG, they do not install or configure the bootloader. I created a short guide on the project main page. Please use the rpms only if you know what you are doing . *I take no responsibility for making your system unbootable* Feedback and suggestions are very welcome!

[opensuse] Basic learning tutorials query
by Linux Tyro 03 Nov '11

03 Nov '11

Hi, THE dvd installation would be completed in two-three days, but again I guess I should have waited, as newer version is coming soon. BUT its, okay for now. AAMOF, I would be required to read some basic tutorials regarding Linux (of course) which are applicable in openSUSE (I mean the principles of which). For this, is there any link on the openSUSE website(s) to get/learn that all...? But please, I don't need the one like 'Installation book' or guide of 11.4. AFAIK, these are readily available. But what I wanted to know like: how Linux (in fact, 'openSUSE' works), what is directory structure and how it is working, how various tasks are handles in Linux, etc...etc... but from the scratch level. -- THX -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Does it mean that packages are same? I mean there are packages on the servers of Linux. Redhat branch (openSUSE, fedora, etc...) uses .rpm to fetch them while Debian branch (debian, ubuntu, mint, etc...) use deb to fetch them, both uses the same packages but to fetch them they use different tools - 1) rpm and second 2) deb, is - Hide quoted text - it like this? -- THX -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
