[solved] error: undefined reference to '\_imp__is_InitCamera'*



  • Hi,

    I am trying to grab an image from an uEye ethernet camera.

    In the project .pro file, I've added INCLUDEPATH and LIBS to point to where the location of the uEye SDK is:

    INCLUDEPATH += "C:\Program Files\IDS\uEye\Develop\include"
    LIBS += -L"C:\Program Files\IDS\uEye\Develop\Lib" -uEye_api -uEye_tools
    

    In my code, I added:

    #include "uEye.h"
    
    HIDS hCam = 1;
    printf("Success-Code: %d\n",IS_SUCCESS);
    INT nRet = is_InitCamera(&hCam, NULL);
    

    When I tried to compile, Qt Creator complains that: mainwindow.cpp:27: error: undefined reference to '_imp__is_InitCamera'
    Strange that I was typing the line is_, the IDE auto-complete the syntax to is_InitCamera.

    What did I do wrong?

    Change
    LIBS += -L"C:\Program Files\IDS\uEye\Develop\Lib" -uEye_api -uEye_tools
    to
    LIBS += -L"C:\Program Files\IDS\uEye\Develop\Lib" -lEye_api -lEye_tools

    And you should avoid to use paths containing blanks: it often cause problems.



  • Thanks, that fixed it!
