28kb? You're only seeing the tip of the iceberg. I just built Qt Hello World myself. It's about sixty megabytes in size.

    jart@debian:~/scratch/qtproject$ qmake -project
    jart@debian:~/scratch/qtproject$ make
    jart@debian:~/scratch/qtproject$ ldd ./qtproject | grep -Po '(?<==> )[^ ]*' | xargs ls -alH | awk '{x += $5} END {print x / (1024 * 1024.)}'
    59.5916
That's bigger than I expected to be honest.



Aren't you also listing all the non Qt libs here ? X11, libinput, pulse audio, dbus, gstreamer, OpenSSL... e.g. here on linux for a static build of Qt (which links against both X11 and wayland platform plug-ins, and uses an embedded libpng, harfbuzz, freetype, etc...) a QWidget hello world comes out at 14 megabytes.


Id say its fair game if building hello world links those gstreamer and openssl.

why ? it entirely depends on how your linux distro chose to build Qt, not on Qt itself.


Because application can't run without those libraries. It's like comparing Java application without taking JVM into account.


> It's like comparing Java application without taking JVM into account.

no, it's not. The "equivalent" of the JVM would be the libQt5{Core,Gui,Widgets...}.so ; but here we are talking about the operating-system-provided libraries, so it is like comparing with a Java application, with the JVM, and also for instance all the MS Windows system libraries, or all the macOS frameworks like CoreFoundation, etc etc.


OK, so in this context the app is X MB. If all distros link those libs with libre cote and ui, for all intents and purposes, it takes X MB. If some dont, then lets discuss it (but if you can link to gstreamer and openssl to build a hello world, the issue is not entirely on the distro shoulders)
