Qt Application Calling Dll from Fortran - windows

Question

Here's the problem I got for Qt Application(Qt4\Qt5) calling Dlls from Fortran(CVF\IVF).
Qt4+Dll(CVF)+WinXp
It works fine in my PC both in QtCreator and as solo.
not working in other's (xp or win7/8)
the error is "dll not loaded" ( .isLoaded() false message)
then my PC's dead, got new one and immigrated to Qt5 with IVF.
But still the problem:
Qt5+Dll(IVF with complier_platform win32)+Win8
It works fine in my PC both in QtCreator and as solo
not working in other's (xp or win7/8)
the error is "dll not loaded" ( .isLoaded() false message)
Well, after trying them from various PCs:
I suppose it's not the platform problem(32bit or 64)
I am sure the dll path is correct when calling
Qt calling codes are
if(stlDll.load()){
myfun fun1 = (myfun)stlDll.resolve("STLDLL");
if ( fun1 ){
fun1(fileName_For90);
}
}
else
QMessageBox::information(NULL, "File Missing",tr("dll not loaded, the Directory is ")+dllPath, QMessageBox::Ok);
the error is always "dll not loaded", however that's the very right dllPath where I can find the dll with eyeballs but the Qt Applicaiton can not.
Fortran dll compiling codes are :
!DEC$ ATTRIBUTES DLLEXPORT,ALIAS::stlDLL

Answer 1

Typically DLL's compiled with Intel Fortran are dynamically linked to the Intel Fortran (and underlying Microsoft C++) runtime DLL's. Are your Fortran DLL's compiled and linked that way?
If so, you need to have the Intel Fortran runtime DLL's (and the underlying Microsoft C++ runtime DLL's) installed on the target machine.
You can get installation packages for the Intel Fortran runtime DLL's from the Intel website in the same manner that you acquire downloads of the compiler (or see here). You can get installation packages for the Microsoft C++ runtime libraries by searching the Microsoft website (they are Visual Studio version and service pack specific). Alternatively, merge modules and installation exe's for the runtimes may have been installed on your machine as part of the Intel Fortran and Visual Studio installations.
