libvlc_new (0, NULL); segmentation fault

Question

I have a problem when I use this line :

   vlcInstance = libvlc_new(0, NULL);

vlcInstance is declare in my header:

  libvlc_media_player_t *vlcPlayer;

I am using Qt 5.0.1 and I have this error:

The inferior stopped because it received a signal from the Operating System.

Signal name : SIGSEGV Signal meaning : Segmentation fault

Can anyone help me?

I am using Qt Creator 2.7.2 with QT 5.1.0 on 64-bit Kubuntu 13.04. I'm also using vlc-2.2.0-git.

I created a new QT project.

I added this to the new project file (change your vlc paths as needed):

INCLUDEPATH += /home/linux/vlc/install/include
LIBS += -L"/home/linux/vlc/install/lib" -lvlc

bare-bones main.cpp (including your code that apparently segfaults):

#include <QtDebug>

#include "vlc/libvlc.h"
#include "vlc/libvlc_media.h"
#include "vlc/libvlc_media_player.h"

int main(int argc, char *argv[]) {
    qDebug() << "Starting...";

    libvlc_instance_t* p_instance = libvlc_new(0, NULL);
    qDebug() << "p_instance" << p_instance;

    if (p_instance) {
        libvlc_media_player_t *p_media_player = libvlc_media_player_new(p_instance);
        qDebug() << "p_media_player" << p_media_player;

        if (p_media_player) {
            libvlc_media_player_release(p_media_player);
        }

        libvlc_free(p_instance);
    }

    qDebug() << "Exit normally";
}

This runs just fine for me, no segfault:

Starting... 
p_instance 0x19140f0 
p_media_player 0x19da6d8 
Exit normally
