I am using semaphore.h I declared a variable of type sem_t. I am able to use the variable without even calling sem_init or sem_open, and it is working properly.if the variable is automatically assigned some value? Also would I run into any trouble doing so?
View 1 RepliesI have a struct (small instance so not using code brackets )
struct random {
int a;
int b;
}example;
What i am trying is
example={0,0};
and it gives an error how to initialize all the entries within a struct to zero? In the above example i have used integers but what if they are some other data structure for example another structure?
Following is the way I saw a variable initialized in C
Code:

I have initialized variables in past but above initialization I could not understand what is it?
I'm making script for automated compiling of one program which would output builds optimized for many architectures. For clearancy, I do each build in it's own catalogue and list of builds with their respective catalogues would be stored as array. I'm using this guide as reference. It describes making array as naming a variable with additional brackets denoting it's position in array.
In my code, it looks exactly like this:
Code:
mtune[1]="build/mtune/athlon"
mtune[2]="build/mtune/athlon-4"
mtune[3]="build/mtune/athlon-mp"
[code]....
But upon invoking $mtune or any $mtune[x] variable, output is blank, like the variable(s) were never initialized. What am I doing wrong?

The code below defines an array of structures in a class. I would like this to be a Static array and then initialize the array in a initialization method. I understand that initialization lists are the way to go but due to the size and complexity of the array I plan on using (the example below is a simple snippet that illustrates the problem) I would like to use the initialization method. However, I cant even get this thing to compile. The error says the reference to the ArrayOfStructs in the initialization routine is undefined.

I made 2 files which are different from the program above one is temp1.h and another is temp2.c to understand how extern is used. So here is temp1.h
Code:
#include<stdlib.h>
typedef struct node * bond;
extern int jk;
and temp2.c is
Code:
#include<stdio.h>
#include<temp1.h>
struct node {
int data;
[code]...
I had declared jk in temp1.h as an extern int so why can I not initialize it in temp2.c?
Kernel 2.6.21.5, slackware 12.0 as 2.17 [I am speaking here about 80x86 processors, with their segment registers SS, DS, CS, ES.] In a source file for as, I wrote
Code:
.section _STACK
.rept 4096
.word 0
.endr
Now, in the .text section, I want to initialize SS, the stack segment, to point to the _STACK section. In other assemblers, there was a special section for the stack, and the linker cared about initializing SS. Here I use a common section for the stack. For a segment such as DS, I could write
mov ax,_DATA
mov ds,ax
But I don't think mov ax,_STACK would do with as/ls.how do I initialize SS?

I have downloaded mplayer svn slackbuild script for slackware 12.2 and converted into tgz package and installed it on my slackware 12.2 system. I was using it with slackware 12.2 early and it worked fine. i formated my hard disk to give slackware 13 a try. and later when i installed slackware 12.2 and installed mplayer it is not opening i mean not initializing when i click mplayer icon from the multemedia menu or if i click a videofile and tell it to open with mplayer both ways its not working i tried reinstalling mplayer
but still not working.
I need some help. I'm not exactly new to linux but I'm not an expert either. I decided to try and play around with GRUB and see if I could get the GRUB gui and themes working. Apparently I did something and now, when I start up my computer, all I get is code...
I know little to nothing about grub. I will welcome any and all help or advice with this. Let me know if you need any other information and I will try to post it. Also, I have no idea whether I am running legacy or 2. It originally told me I was running legacy and I attempted to upgrade to 2 but I have no idea if it actually upgraded.
I am having a very serious problem! GRUB won't allow me to start up windows 7. Each time I select it from the prompt, I am given a blank screen with only the cursor blinking and mocking me. Ubuntu works perfectly fine, but when I try to mount the windows 7 volume, it tells me that it is unable to mount the location because of an input/output error. I havnt done anything to make me believe I have caused this abd I am in complete shock that this has even happened. Both operating systems were running completely fine and then suddenly, windows won't boot up.

If I log out of the user account and log into root, all of the sudden i can open the icon in both root AND the user account. It also shows up in /media/.

As in the Subject, after the machine boots up and I'm logged in, there is no sound using local software (video or audio, such as VLC) or web-based (as in Pandora, ....., etc).
So I have to bring up Yast -> Hardware -> Sound, then Delete the current driver, then select "Add" to re-add it ... it detects the hardware fine, and sets up the sound driver, and I then get sound. However, when I shut down the machine and eventually fire the machine back up, no sound.
Driver: snd_intel8x0
Controller: CK804 AC'97 (onboard nVidia chipset)
I ran dmesg and saw nothing out of the ordinary. All appropriate files/entries exist in /etc/modprobe.d/
What can I do so that the driver is loaded at each startup?
I had a response out in alt.os.linux.suse who said the problem went away when they switched to GNOME ... so is this possibly a KDE issue? (I haven't tried restarting and running GNOME versuse KDE).

View 1 Replies View RelatedI finally upgraded from my old Passive Nvidia 6600GT video card to a passive ATI 5750. Using Fedora Core 12, 2.6.32.16-141.fc12.i686, On boot the native driver worked but the card got hot as it was not de-clocking into idle mode like it does under windows 7.
So I reluctantly installed the closed source ATI driver from RPM Fusion
I also added nomodeset to the kernel start-up
Previously I was using the native standard built in Nvidia driver.
The new ATI driver seems to be running with correct entry in Xorg.conf and now it runs very cool at idle just like under windows :-
However the control center will not start...There was a problem initializing Catalyst Control Center Linux edition.
Also some commands using aticonfig return this error...
These libs are on the system in /usr/lib/catalyst
I am also getting video tearing in movies with mplayer and VLC. I have tried the options...
Which added a vsync entry in xorg.conf, but No luck...I think I need to get catalyst control center (amdcccle) running which I has a sync on refresh option radio box that may solve my video issue.
I can live with these errors but the video / movie tearing is a show stopper.
I am getting headache over this trying to find a solution to these issues. ATI and Linux still do not mix well
