How do I compile a .exe file which I can run on any windows computer?

SGaist

And that's your job to copy it over to the folder of your application. windeployqt can't guess where the .dlls are stored. It knows where the Qt dlls are because it's known at installation time, however there's no standard path to look for to get the .dlls. They are not used at all at linking time so it's impossible to know where to look for them.

I can now launch my .exe after running windeployqt and copying SDL2.dll to the same directory. However, I would still like to get this down to 1 file.

As @SGaist mentioned earlier, the only way to get this down to 1 file is to use static linking. You need to build a statically-linked version of Qt yourself, and then set your project to use the static libraries of Qt and SDL.

StevenD

Right, but how do I build a statically-linked version of Qt? I seem to be missing folders or files from the various tutorials I have found.

Right, but how do I build a statically-linked version of Qt?

In summary:

Obtain the Qt source code
Add the -static option when configuring Qt
Build Qt

Instructions to configure and build are at http://doc.qt.io/qt-5/build-sources.html

An example set of commands is:

> configure.bat -prefix "C:/Qt/MyStaticBuild" -opensource -confirm-license -nomake examples -nomake tests -static
> make
> make install

Remember, using static linking means that your application cannot be closed-source.

I seem to be missing folders or files from the various tutorials I have found.

Which tutorials, and which folders/files?

StevenD

Thanks for the help. I have successfully downloaded the source code, and now have the files that I needed. However, I am having some issues. Mingw is not working.

mingw32-make: *** Error -1
.   Stop.
mingw32-make: *** Waiting for unfinished jobs....

...and then it hangs forever.

mingw32-make: *** Error -1

There should be more info near this line that describes what the problem is. What was it doing just before the error?

Anyway, run mingw32-make again and see if it continues from where it last stopped. (It will first scan the files that have already been processed)

I tried to build Qt with PowerShell a few months ago, but it failed. I didn't investigate why, but I suspect it's some kind of incompatibility between PowerShell and the old Batch files.

cmd.exe worked for me; see if that helps you.

StevenD

cmd gives me almost identical output:

SGaist

I'd first cleanup to ensure there's no remaining from your old build tentative.

Also, consider doing out of source builds, that will simplify things if you want to build Qt for several architectures or make different static/shared builds.

StevenD

What should I clean up? Attempting to run mingw32-make clean results in mingw32-make: *** No rule to make target 'clean'. Stop.

In addition, I do not see any additional files I should delete.

SGaist

Because you are calling configure repeatedly with different options, so you should cleanup between invocation.

StevenD

I know I should clean, but what and how do I clean?

jsulm

@StevenD You should start with fresh Qt source tree and do out of source build as @SGaist suggested.
Out of source means:

c:\qt_source
mkdir c:\qt_build
cd c:\qt_build
..\qt_source\configure.exe...
make

So, basically you call configure and make from outside of the Qt source code directory.
In general you should read http://doc.qt.io/qt-5/build-sources.html

StevenD

Right, I now have a different problem:

C:\qt_build>..\Qt-3.0.1\5.9.2\Src\configure -opensource -confirm-license -nomake examples -nomake tests -static
+ cd qtbase
+ C:\Qt-3.0.1\5.9.2\Src\qtbase\configure.bat -top-level -opensource -confirm-license -nomake examples -nomake tests -static
Host platform 'win32-g++' is invalid. Aborting.

SGaist

From a clean source ?
What command prompt are you using ?

StevenD

I've tried using cmd and PowerShell, in that order. Both give the same ouput.

This may be a problem with Windows. I've recently started having... issues with it that are not related to Qt. Random applications suddenly can't run on my pc... I had this pop up with Qt Creator, Cygwin, and some other things.

SGaist

IIRC Windows latest updates may broke things in surprising ways.
