Qt Static Build Is Very Big

Thank @mrjj very much.
If I made my project on Qt and I would make it static build And .Exe will be a maximum of 15 megabytes, UPX will bring it down 15 -
min(15 * 50 / 100, 15 * 70 / 100), This is a lot for me.
I would be happy with only about 500 kilobytes :(.
Let's take the name of everyone skype installer. Where can it be written?
Excuse me to get my problems out of Qt. I did not want a flood this topic.

@Taz742 From the beginning of this thread it has been unclear to me what you actually want to do. For example, if you want to have a simple Windows-only application with a graphical user interface which does only one simple thing and whose size goes under 5MB, Qt isn't a good solution for you. See https://blog.qt.io/blog/2017/05/31/qt-lite-qt-5-9-lts/ for size comparison and you can see that under 5MB is so-and so with the Lite system, but under 1MB is unrealistic. The very small applications you see on Windows use some lighweight libraries or maybe only Microsoft's own Windows APIs. The reason they are small is because Windows has many libraries installed by default, not because Qt is bloated. If just under 5MB is acceptable, you can try e.g. wxWidgets, see https://wiki.wxwidgets.org/Reducing_Executable_Size. If you have a command line application without windows and widgets you shouldn't be using Qt in this case at all.

I have no idea what this shows.
Normally upx compress it to 1/3 of size.

@Taz742 About the Qt Lite I would say that it's too much hassle for just one small Windows application (with the caveat that I haven't actually tried it). Without the commercial licence you have to manually edit hundreds of things and then compile Qt. With a commercial licence comes a GUI configuration tool.

In order to get what I needed to write the WIN API application in Dev C ++.
He did not request other and other platforms .dll and other files. (Only .exe).

Only this code can only be achieved with the following picture:

Now I can not create http file downloader.

@Taz742 "Now I can not create http file downloader" - why not? You don't have http networking features available? Use for example libcurl, it was already mentioned. But this has nothing to do with Qt so you will get better help somewhere else.

Taz742

@Eeli-K
Because libcurl can not be installed for Dev.
When I used to use the visual studio and transferred my project to visual studios that I had written on Dev. He asked .dll another computer to connect to the program.

Did you try to build libcurl with your compiler?

Taz742

@jsulm
I tried but I could not

@Taz742 That's offtopic but you need to link c++ redistributable statically also to have dependancy free application when compiling with MSVC. https://stackoverflow.com/questions/37398/how-do-i-make-a-fully-statically-linked-exe-with-visual-studio-express-2005
