Devastating Deployment Issues

[xtlc]

I really am totally clueless after reading http://qt-project.org/doc/qt-5.0/qtd...t-windows.html and many similar articles and googeling the last 4 hours. I cant deploy my app. I wrote it in QT5.1.0 and I am completely confused... please help me.

- I am using Qt5.1.0
- MS Visual Studio 2012
- QExtSerialPort
- QCustomPlot

I tried the static and the shared library approach, but failed on both - usually in the first line of the tutorial. For example where it says:

Now run qmake to create a new makefile for the application, and do a clean build to create the dynamically linked executable:

nmake clean
qmake -config release
nmake

So I do: WIN+R, Enter -> CMD -> Enter
If I type "nmake clean" I get:Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. Alle Rechte vorbehalten.

c:\Users\rt\Desktop\GUI>nmake clean
Der Befehl "nmake" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.

Which means Command nmake cannot be found in english.

My program is called GUI and I can execute it just fine from inside the QT Creator. When I press STRG + R I see an folder being created in my programs directory, which is called build-GUI-Desktop_Qt_5_1_0_MSVC2012_64bit-Release - but I cant open the GUI.exe which is located there. It is only 383Kb big too. Which is awkwardly small I think, bc some of the to be included files are already bigger. I just want one big executable with all I need inside. I will update this thread if I try / find out more.

You will have to open a command shell that has the necessary paths set to include the path that contains nmake.

There is usually a link for that in the start menu folder of visual studio.

you mean the Visual Studio Developers CMD or however its named? I did try that. I got an error when I did "nmake clean" there.

Google for "visual studio command prompt"

The "first line of the tutorial" is part of the instructions for building your Qt project from a command line. If you have already built your project from an IDE then start here.

Perhaps you can tell us what you files and directories you deployed for your dynamically linked Qt application and what "Devastating Deployment Issue" you experienced etc.

When I use the VS CMD I get:

c:\Users\rt\Desktop\GUI>nmake GUI.pro

Microsoft (R) Program Maintenance Utility, Version 11.00.50727.1
Copyright (C) Microsoft Corporation. Alle Rechte vorbehalten.

GUI.pro(7) : fatal error U1036: Syntaxfehler: Zu viele Namen links von "="
Stop.

c:\Users\rt\Desktop\GUI

Which says sth like "Syntax error: Too many names left from "=" stop.".

Here is also my GUI.pro file:

The german words next to "error opening file" can be translated as "System can't find specified file".

I don't know why you did that. It certainly doesn't say to do that in the instructions. A PRO file is an input to qmake, qmake produces a Makefile which is the input to nmake.

In any case, as I said above, if your project builds in your IDE then you do not need to build it again from the command line.

Your Dependency Walker screen shot indicates that you made no progress following the Creating the Application Package. There are some difference with Qt5, so you should read the Qt5 version of the same document. You need to start by copying the missing Qt5 DLLs into a deployment folder along with your compiled program.

I will proceed with the *.dll thing But the other question I mentioned above: My GUI.exe I can find in the release folder is so tiny... 383kb. I think that is to small?

[xtlc]

depends2.jpgI managed to remove all the warnings. So what would be the next step? I read in ChrisW67's link I have to insert the msvcp90.dll
(because I use VS) too. Is that correct? Or is this just for a VS 2008 version? I use VS 2012.

If I know double click my GUI.exe I get:error.JPGTranslated word by word this says "The application could not be started correctly (0xc000007b). Click Ok, to close ...".

EDIT: I copied the *.dll's in the folder "release" which is created, when I press STRG+R in QT.
This is what the folder looks like right now:folder.jpg. I just wanna have one big exe that I can move from PC to PC.

You will need the Visual C++ 11 version of that file. I guess it is called msvcp110.dll but someone with the Microsoft tools would have to verify that.

If I know double click my GUI.exe I get: ... Translated word by word this says "The application could not be started correctly (0xc000007b). Click Ok, to close ...".

Have you created the "platforms" folder and copied "qwindows.dll" into it?
Have you copied the DLLs for the third-party libraries in to the folder or have you built their sources directly into your executable?

I just wanna have one big exe that I can move from PC to PC.

To get your "one big executable", that I assume you want to work without an installation step requires:

• building Qt itself (and its dependencies) from source for static linking,
• building your third-party libraries from source for static linking,
• building your application to statically link against the libraries above after modifying it to account for any plugins it needs, and
• complying with any license requirements when distributing the executable.

It is easier to create a folder with a dynamically linked executable that you either wrap into an installer (using NSIS, Innosetup or similar) or distribute as a zip file. In short, walk before you try to run.

I am not quite curtain of what you mean with "platforms" folder? Have you seen the 9720 screenshot?
