Procedure entry point not found

  • I just finished a program in Qt Creator 3.0.0 based on version 5.2 (MSVC 2010, 32 bit) and I was pretty upset that Qt Creator didn't set static stand alone exes so I could make my program have an installer.

    I clicked the exe of my program and It said I needed about 10 dll's. After I made a new folder, put all the dlls inside, it said, "The Procedure entry point InterlockedCompareExchange@12 could not be located at the dynamic link library c:/test/program.exe." when i tried to click my program.exe to run it.

    I am new to Qt and I am looking for an easy to understand answer to how to make my program run and what that error message is. Thanks.

    I am using the MinGW compiler. Please reply

    You can't mix MSVC Qt libraries with MinGW ones (that is, you need to use MinGW Qt when you compile with MinGW).

    Please consult the official "deployment guide": (see the "Shared" section).

  • Morgan Peters,

    as sierdzio said, if you compiled your program with GCC/MinGW, then you will need to ship the GCC/MinGW-based Qt DLL's along with your program. And if you compiled your program with MSVC, then you'll need to ship the MSVC-based Qt DLL's along with your program.

    And if you want a fully self-contained EXE file that does not depend on any external Qt DLL's, then you'll have to compile Qt yourself - as static library.


    BTW: I suggest you use "Dependency Walker": to find out on which DLL's your program depends exactly.
