Application crash when it run with Qt creator but works after "deploy"


  • Hi,
    I have a problem with several applications using hidapi on Windows. Last week, it worked but for a couple of day, it crash.

    • I have no error during building.
    • if I copy .exe files on folder with useful dll, I can run the application without problem.
    • I have reinstall Qt without success.
    • It works on another PC (on windows 8). My computer is under Windows 10 (I had the same problem on Windows 7 yesterday, before updating my Windows version).
    • When I comment the line calling function of the library, it works

    I don't know where to look.

    main.cpp :

    #include <QGuiApplication>
#include <QQmlApplicationEngine>
#include "hidapi.h"

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;

    struct hid_device_info *devs=NULL;
    devs = hid_enumerate(0x0, 0x0); //If I comment this line, it works 
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    return app.exec();
}

    .pro

    TEMPLATE = app

QT += qml quick
CONFIG += c++11

SOURCES += main.cpp

RESOURCES += qml.qrc

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Default rules for deployment.
include(deployment.pri)

LIBS += -L$$PWD/ -lhidapi

INCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/

    folder Qt project :

    Hi,

    When starting the application from Qt Creator, hidapi.dll won't be found. One solution is to go in the Run section of the Project Panel. There edit the PATH environment variable and add the path to test/.

    0

  • Thank you to help me.
    If I add path to test as bellow, it still not working.

    C:\Qt\5.2.1\mingw48_32\bin;C:\Qt\Tools\mingw48_32\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Qt\5.2.1\mingw48_32\bin;C:\Users\MyName\Documents\test

    And I don't understand why hidapi isn't found. I have on the .pro :

    INCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/

    and I also add hidapi.dll on folder "build-test-Desktop_Qt_5_2_1_MinGW_32bit/release" next to .exe

    If you copy that dll in the build folder, does it still fail to start ?

    0

  • Yes, if I copy .dll next to .exe, it still not working

    Just to be sure we are on the same line:

    1. You build your application
    2. You copy the DLL in the build folder
    3. You call run from Qt Creator
    4. Crash ?
    0

  • Yes.
    On the other side, if I copy .exe on folder with hidapi.dll and other dll of Qt (as I deploy). I can execute the application without crash.

    Strange… Does hidapi.dll have any dependency ?

    0

  • no, I don't think.
    And when I copy .dll on "deploy folder" I don't added anything except hidapi.dll and Qt dll

    0

  • I found the problem. The difference between "deploy" folder and project folder is : msvcr120d.dll. If I add this dll on project folder, it works.
    Thank you for your help

    @helenebro
    actually the msvc runtime binaries should also be available system wide (e.g. contained in the PATH), so something went wrong during installation. Or do you have altered the environment variables in the QtCreator project settings?

  • I don't know if it's a installation problem but I don't found msvrc120d.dll on C:/Windows/System32 or on C:/Windows/SysWOW64.

  • Hi, msvcr120dl.dll usually you will only obtain by installing Microsoft Visual Studio 2013. Because it's the debug flavor of the normal msvcr120.dll, and that dll is much more easy to find.
    Try building your app in Release mode, then you might get rid of your dependency on msvcr120d.dll.

  • If I build my app in Release mode I have the problem if msvcr120d.dll on my folder. I think it's because library hidapi is build with visual studio.
