C++ API DataStage 0xc000007b

Question

Does anybody may give someone advice for me how realise DataStage connection?
API Link: https://www.ibm.com/docs/en/iis/11.3?topic=interfaces-infosphere-datastage-development-kit
I try include the api but when I run the program I get error: 0xc000007b
Where I made a mistake?
Thanks for anwer!

main.cpp

#include <iostream>
#include "dsapi.h"

int main() {
    DSSetServerParams("domain", "username", "password", "server");
    char* result = DSGetProjectList();
    if(result != NULL)
    {
        printf(result);
    }
    else
    {
        printf(DSGetLastError());
    }
    return 0;
}

Looks like that wow64.dll have not x32 analog. It is correct?
How have working plase this library?

Probably your app is 32-bit, but you're attempting to load a 64-bit module/DLL, or vice-versa (app is 64-bit, and you're attempting to load a 32-bit module/DLL). — PaulMcKenzie, Jul 06 '21 at 16:36
And how did you check this? If you have DLL's that have the same name, but found by the Windows DLL search algorithm, Windows will attempt to load the DLL, regardless of the type of application you will be running. If you're running a 32-bit app, but Windows finds a 64-bit DLL that matches that name, Windows will attempt to load it, and thus get the error. Same thing with 64-bit app and 32-bit DLL. [See this answer](https://stackoverflow.com/questions/28299246/0xc000007b-error). — PaulMcKenzie, Jul 07 '21 at 07:14
Also, showing us your source code for the main program does not help in the issue. Your 32-bit program and 64-bit program will look exactly the same in terms of source code. The problem is a runtime issue, not a compiling issue. So is your program 32-bit or 64-bit? You haven't mentioned that at all. — PaulMcKenzie, Jul 07 '21 at 07:17
@PaulMcKenzie I used dumpbin.exe /headers to dll and saw x86 header. In my CmakeLists.txt seted flags -m32 for libs and executable. I will try run the program at stantion with x32 windows tomorow. But I not shure that it will fix problem. Do you have other variants? — Wolfgang, Jul 07 '21 at 14:26
Windows OS doesn't care what dumpbin has. Again, if a DLL's name matches what Windows finds at runtime, Windows will try to load that DLL. Windows doesn't skip over the DLL if it doesn't match the bit-ness of the application. That's what causes `0xc000007b` errors. [Here is a description of the DLL Search Order](https://learn.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-order). — PaulMcKenzie, Jul 07 '21 at 14:39
@PaulMcKenzie, How I can checking dll bits class? Do I have to start program on the 32-bit OS for resolve ? — Wolfgang, Jul 07 '21 at 16:26
See the linked answer. You need to use a utility that shows what DLL is being loaded and where. — PaulMcKenzie, Jul 07 '21 at 16:27
[Process Monitor](https://learn.microsoft.com/en-us/sysinternals/downloads/procmon). Again, see the linked answer. I have never used the tool, but the answer that has 15 upvotes used it to diagnose the error. — PaulMcKenzie, Jul 07 '21 at 16:46
@PaulMcKenzie Hello. Can you comment Exit Status: -1073741701 ? How can I identify bad dll? — Wolfgang, Jul 08 '21 at 06:46
Your `C++` code seems legitimate. I can see that you are making a decision to go with the x86 (32-bit) development as thoroughly described in the `CMakeList.txt`. You might not be safe from a lurking x64 DLL here or there. Referencing any incompatible 64-bit DLL reference will raise the `0xc000007b` . I suggest that you rewrite `CMakeLists.txt` to accommodate 64-bit references for troubleshooting now. — Bilal Qandeel, Jul 12 '21 at 23:45

You might want to add the following two lines to ensure compiling your code as 32-bit:

set(CMAKE_C_FLAGS -m32)
set(CMAKE_CXX_FLAGS -m32)

The legends say that if you would use Eclipse IDE does that automatically where CLion does not necessarily do.

Thanks! I fix it with x86 Visual Studio Console and flag -A Win32, maybe it is work too. – Wolfgang Jul 13 '21 at 06:27
