Debug: Program received signal SIGSEGV, Segmentation fault
« on: July 26, 2008, 10:47:56 am »
Hi,  :(

I get same strange problem with a my program so try to use debug and back-running go to try debug in samples of SFML.

I get error:
Quote
Program received signal SIGSEGV, Segmentation fault

in any programs when go to use debug function of CodeBlocks.

I see that problems begin when start to use graph with
Code: [Select]
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Pong");
Probably is only a case.. I'm not an expert din debug/codeblocks so..

someone can help me please?
I just spent a lot of time for this.

I work on windows with: SFML1.3 / Code::Blocks / Mingw / gdb.exe.

I don't get any problem with simply programs that don't use library:
Code: [Select]
for ( i=1; i<=3; i=i+1 ) { printf("i=%d ",i); }

I can't found documentation about this online.. only a similar problem:
http://forums.comodo.com/bug_reports/conflict_with_gdb_debugger-t21329.0.html;msg147164


Now I make an simple code: new project with this code:
Code: [Select]
#include <SFML/Graphics.hpp>
int main() {
    sf::RenderWindow AppGr;
    return EXIT_SUCCESS;
}
and
Code: [Select]

#include <SFML/Window.hpp>
int main() {
    sf::Window App(sf::VideoMode(640, 480, 32), "SFML Window");
    return EXIT_SUCCESS;
}


This 2 simple codes have the same problem:
starting debug with initialize variable as sf::RenderWindow or sf::Window
generate SigSegV
if I remove variable init line debug can run property

Now I try other library and found that I haven't any problem
with Sockets sample in debug mode. Any debug function go right.


Thanks for any suggestion.

If possible you might try downloading and installing SFML from scratch. There's no reason that I know of that code should be segfaulting. I'm using the exact same code on the exact same platform (Windows/MingW/Code::Blocks) without any problems, so my best guess is a corrupt library. :?

Hi Puck.

All SFML programs run well on my PC.
Only when try to use GDB debugger(breakpoints) I get SigSegV.
Do you use that?

Thanks
