[Mingw-cross-env-list] Generated .exe does not work

[Thomas Spitzer]

Finally I am able to buld my hello world application with MXE.
I can successfully build for 4 tagets:

- x86_64-w64-mingw32.static
- i686-w64-mingw32.static
- x86_64-w64-mingw32.shared
- i686-w64-mingw32.share

Unfortunately all 4 do not work on my 64 Bit Windows 7

i686-w64-mingw32.shared (see shot1.png)
after running windeployqt.exe: (see shot2.png)

i686-w64-mingw32.static (see shot3.png)
windeployqt.exe: generates error:

C:\Qt\Qt5.10.0\5.10.0\mingw53_32\bin>windeployqt.exe
C:\Users\thomas\Downloads\archive\archive\gui\src\qt_hallobuild\i686-w64-mingw32.static
C:\Users\thomas\Downloads\archive\archive\gui\src\qt_hallo\build\i686-w64-mingw32.static\qt_hallo.exe 32 bit, debug
executable
C:\Users\thomas\Downloads\archive\archive\gui\src\qt_hallo\build\i686-w64-mingw32.static\qt_hallo.exe does not seem to be a Qt
executable.

For the 64 Bit variant it's simmular.

There must be something essentional I've missed. Do you see it?

Hi,

seems you have a release build, so you need the Qt libraries without the
'd' suffix (Qt5Core.dll instead of Qt5Cored.dll). Might be windeployqt is
not able to handle that.
I prefer to use tools/copydlldeps.sh/py from mxe, it crawls through the
libraries and copies the necessary dll-s they link with.
Note that it does not copy the plugins you use, so you should copy those
manually, you will at least need the platform plugin for windows
(platforms/qwindows.dll).
You might also need to specify a qt.conf so that Qt knows where to find them

$ cat qt.conf
Prefix=.

Br,

Robert

Thanks, it works now!

As Robert said, use the correct dll files. The screenshot tells you
which is missing.

The static build contains everything so you do not need any external dll
files.

The program runs now, but the function "app.exec()" crashes with a
null pointer exception :-(
