I've been thinking to adding the ability to update some code I've been working on from the internet. So basically writing some C/C++ code that on startup of the software looks across the next to a server to update itself. However I have no idea how to do this, can anyone point to to linux tutorials or examples which show how to do this?

View 2 Replies View RelatedAre the programs written on schedulers ,thread library , process management, memory management, et al called systems programs ? How are they different from the programs that implement functions like open() , printf() , scanf() , read() .. they have a prefix sys_open, sys_close, sys_read etc , right ? Is there any difference of hierarchy between the programs that implement system calls and system level programs like that implement thread library, process management , memory managemnt etc..

After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.
Even this code will fail to link:
Code:
#include <gtk/gtk.h>
int main(int argc, char** argv) {
gkt_init(&argc, &argv);
gtk_main(); }
(Compiled with the standard commands to compile Gtk+ stuff)
I always get the following output:
Code:
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time'
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time'

View 4 Replies View RelatedI am working on a project with a lot of vector math and I'd like to find a way to speed it up.eading about SSE, but I've found no explanation on how to actually use it in code (was looking for some kind of hello-world example, complete with compilation instructions).Does the gcc compiler automatically make use of SSE, if you add the -sse(2,3) option on the command line? Or are their specific functions/libraries you need to call?
View 12 Replies View RelatedIs there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.

View 3 Replies View RelatedI've been converting some C code to assembly for my homework; it was going well but I'm having trouble with a for loop for hours. I could not understand where is the problem and decided to ask. I'm posting the part where I'm having trouble of my C-code and assembly-code; every other part of codes act same and the variable values are same. I'm waiting this two codes to act same, but they don't.
Code:
mov ebx, [result]
mov eax, [i]

Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system.
