Segmentation fault

Xav12358

Hello,
As I run my application I get that segmentation fault on a deployement execution:

[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.
0x00007fffef4e6b8c in ?? () from /usr/lib/x86_64-linux-gnu/libQtTest.so.4

First I don't understand why on my computer it works properly and on deployement execution I get that error?
Then I use Qt5 why libQtTest.so.4 is used?

I am really stuck, can someone help me?

@Xav12358 How do you deploy your app to another computer?
You need to deploy all needed Qt libraries and plug-ins together with your application.
Check this: http://doc.qt.io/qt-5/linux-deployment.html

Just to add more info
In fact that problem appends when I try to add a compiled cuda library.
I compile a cuda library which contains few functions and I generate a libMyLibraryCuda.so.

Now I want to use it in QtCreator Project. As soon as I use an object from the libMyLivrarycuda.so there is a segmentation fault.

Here is the compilation library part:

[/code]

And the main file:

[code]#include <QApplication>

#include "cuda/Resizer.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    gpu::Resizer *p = new gpu::Resizer(640,480,gpu::Resizer::DownSampling,gpu::Resizer::Gray,2); // ligne error

    return a.exec();
}

[/code]

When I comment th ligne "gpu::Resizer *p ..." the program works but when I use this line there is a segmentation fault.
But When I remove all Qt Object and I put the line gpu::Resizer *p, it works.

Why when I add Qt SDK on the project there are problems?

I am really stuck.```

I try to compile the project on my other computer in qtcreator. The compilation works fine but the execution give me the same error:

 There are much more library and it inclued also Qt library :

    ```
libQtOpenGL.so.4 => /usr/lib/x86_64-linux-gnu/libQtOpenGL.so.4 (0x00007f78a2f65000)
    libQtGui.so.4 => /usr/lib/x86_64-linux-gnu/libQtGui.so.4 (0x00007f78a2271000)

    libQtCore.so.4 => /usr/lib/x86_64-linux-gnu/libQtCore.so.4 (0x00007f78a1b57000)

Why?? It is only a library compilation without Qt :(

Can you share the exact stack trace you get when the crash happens ?
