My program is to find the values of variables using matrices and in matrices using GAUSS ELIMINATION method. It gives segmentation fault then I input the values of coefficients of the variables.

I am using Ubuntu 9.04 linux 2.6.28-11-generic. When I write a program that gives the "Segmentation fault" error, or when I send this signal (SIGSEGV) to a program, the "Segmentation fault" is shown and no core dumped. When I look for "core" file in the current directory, I can't find it, too.

After re-installing my gnome desktop environment, my skype stopped working. I tried to re-install it. I found out it re-installs without any error but it doesn't launch and gives me "segmentation fault" error on terminal. I purged skype, deleted the .skype folder and installed it again with no luck. when I try to re-install skype via software center it says: "Sorry, 'skype' is not available for this type of computer (amd64)." what should I do to have the skype working on my system again?

So I've wanting to try out the new development branch of compiz (0.9). I made some slackbuilds a while back and installed all of the necessary packages for the compiz window manager. However when ever I tried to launch the program using "compiz --replace ccp &" I would get a segmentation fault. I forgot about it but today I decided to give it another go and after a few hours I decided to try and see what would happen if I just built compiz-core from source with out using a slackbuild, and sure enough it now works. I have hacked the script trying different combinations to try and make it work but no matter what I try unless I install from scratch (directly into the tree) it will not work. If anyone has any ideas on how to fix this so I can make an actual slack package please let me know. Also I used the main developers forum post as a referencem you can view his instructions here [URL]..

View 3 Replies View RelatedWhen I compile my C program on SUSE, I receive a segmentation fault error. To my knowledge, this occurs when a program tries to recall memory but is not allowed to. So I'm using GDB for the first time to solve this problem. After a series of commands, I reach this point:
Code:

Getting Segmentation fault
I have this basic program that is supposed to scan a string for a delimiter and output which segment of the string the user wants, like awk '{print $2}'. The problem is, I always get a segmentation fault when I run the code and I can't figure out what triggered it.
Here is my code:
Code:
int main(void) {
char *string = "my name is joe";
char dlimit = ' ', *good;
int index = 2, round = 0;
int i, place = 0, t;
[code]....
It keeps track of how many times the delimiter was found with round, and the position of the last found delimiter with place. index is to specify which segment of the string the user wants. One more thing, is it necessary to manually allocate memory with malloc() or calloc() when you can just initialize a variable and it be fine? Like:
Code:
int z = malloc(sizeof(int));
when you can:
int z;

The game is quite old (2002!) and I'm trying to mod the old version of it (1.02a), the jk2ded server linux binary.The game engine loads my mod's .so file which I compiled using:
Code:
gcc -shared -static -g -fPIC g_syscalls.c common.c main.c -o out/jk2mpgamei386.so
So whilst launching the server for the first time, it loads the .so file using dlopen() without problems and the output is:
Code:
Loading dll file jk2mpgame.
Sys_LoadDll(/web/web11/jk2/base/jk2mpgamei386.so)...
Sys_LoadDll(jk2mpgame) found **vmMain** at 0xb2ed9413
Sys_LoadDll(jk2mpgame) succeeded!
[ NT's Fix ] GAME_INIT
and then it works correctly until I try to change the map the server is on currently.When a map changes on the server,the .so file has to be unloaded.After unloading with dlclose() without errors, when the new map is launched the engine tries to reload the .so into the memory with dlopen() but fails:
Code:
map_restart 0
