Creating a static linked exe - what did I miss?

Hi,

1. The usual way to build and install Qt is to use an out of source build and call nmake/mingw32-make install when done.
2. Don't know, not enough details
3. You are using a static build of Qt and I assume you are using a QWidget so you have three modules linked: core, gui and widgets.
   Static builds do not make smaller applications executable. It pulls in every bit of code need from all the dependencies of said executable.

I see. I've tried changing the build command to build to another folder with the prefix thing, but it did not compile. Is something missing?

• configure.bat -prefix C:\Qt\5.9.3\static -debug-and-release -opensource -static -static-runtime -nomake examples -nomake tests -no-icu -optimize-size -confirm-license
• C:\Qt\Jom\jom.exe

You called configure in the same folder without cleaning first ?

I used C:\Qt\Jom\jom.exe distclean first, is that still the correct command?

Edit: I forgot to switch to the new "static" folder before running the build command. It compiled fine this time.

That took care of the installed build warning, but the one about a missing qmlscene remains.

Is this a problem if I'm not using any qml? I assume it can be ignored.

-optimize-size also reduced the size of the exe to 13MB, which can be further reduced to 5MB with UPX. This seems fine for now considering it's with a static runtime and everything.

That still didn't solve the problem with the debug build though. It will instantly show this error:

Not a major problem as I can just debug it with the default, non-static version, but still curious what could cause it? I have no idea what kind of log files Qt writes that might be relevant here.

[SGaist]

No it's not, it's only used for QML.

Did you check the backtrace ?

It breaks here:

I just noticed that this testapp_plugin_import.cpp loads a whole bunch of stuff that I don't use.

Could this be a reason for the exe file being huge?
I tried disabling them in the .pro file using QTPLUGIN -= qgif, but it changed nothing (this file still looks the same after rebuild).

Did you re-run qmake before building ?

Yes, I even deleted the entire build folder to make sure. It re-writes the plugin imports exactly the same.
Manually editing this file to remove the unnecessary plugins shrinks the exe by 1MB (or 300KB after packing), so it doesn't change all that much
