Unable to build standalone executable on Windows 7, Qt5.3.1

[SGaist]

Indeed, depending on which anti-virus you have on your computer, it may interfere with the creation of executable files.

Woo hoo! Turning off my antivirus and running as administrator did it.

[SGaist]

You shouldn't need to run it as admin. Standard user should be enough to build and run.

Continuing with the directions here: https://qt-project.org/wiki/Build_Standalone_Qt_Application_for_Windows

It's unclear where I place the static build. At the highest level of my application? I also get stopped again by the following error in my process. Note that my PATH variable does NOT have a path to qmake, so I put in the full path to be more explicit about everything. I may end up needed an absolute path to mt.exe as well:

@

Open VS2013 x64 Native Tools Command Prompt

cd \Users\blu083\Desktop\MyQtProject\MyProjectApp
C:\Qt\5.3\msvc2013_64\bin\qmake MyApp.pro
nmake release
error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MT_StaticRelease' in MainWindow.obj
cd release
mt.exe -manifest MyApp.exe.manifest -outputresource: MyApp.exe;1

Simple, you don't move a build

Did you cleanup your project before running qmake ?

[blu083]

Yes. But I still don't understand how are my built libraries found. Will these now conflict with files under @C:\Qt@ directory? Can I delete the qt5build directory from my desktop?

I am now getting problems where I cannot build a release via QtCreator:
@
MSVCRT.lib(MSVCR120.dll):-1: error: LNK2005: memmove already defined in LIBCMT.lib(memcpy.obj)
MSVCRT.lib(MSVCR120.dll):-1: error: LNK2005: free already defined in LIBCMT.lib(free.obj)
MSVCRT.lib(MSVCR120.dll):-1: error: LNK2005: malloc already defined in LIBCMT.lib(malloc.obj)

...
LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
@

This problem only seems to exist on the PC on which I did a static build. A new PC, that I just downloaded Qt5.3 onto does NOT get these errors.

[SGaist]

Did you by any chance modify Qt's sources to link against Visual Studio's static run time ?

[blu083]

I followed the directions as closely as I could. My steps are explicitly documented in this thread. I, I don't know what to do anymore. I think I'm going to build chrome apps.

[SGaist]

That part doesn't show anywhere in the thread, that's why I'm asking this. If you didn't touch Qt's sources then you should be linking to the dynamic c++ runtime (which is a good thing).

So the question is, are you setting the MT flag anywhere in your project ? If so then please remove it.

[blu083]

I've searched the overarching .pro and the two sub project .pro files (one I never touch and is an HIDAPI project). None of them make any reference to an MT flag (I'm still searching around for what that flag is and how it could've been set). Here are the contents of my .pro files:

Did you also compile your dependencies yourself ?
