Could not load the Qt platform plugin "xcb" in "" even though it was found #1000

Describe the bug Compile and install strawberry on an ubuntu derivative (Pop! OS)

Cannot start app - I get a QT error. Unfortunately I don't see anything in the QT debug that tells me something is wrong. I know basically nothing about QT but googling this issue yields results like this where there is a clear "cannot load" or "not found" diagnostic message.

Build Process Check out repo (commit 21f1fe52c00d9ebfd5734d475d31b33c912344b5)

mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME/usr .. && make -j 14 && make install

Following the instructions [on the "Compile Ubuntu" wiki age. I did also install libxkbcommon-dev as my initial cmake calls succeeded but included the following:

-- Could NOT find XKB (missing: XKB_LIBRARY XKB_INCLUDE_DIR) (Required is at least version "0.5.0")

This is what's wrong: could not connect to display :0 Are you running on the terminal without a X11 session? Are you trying to start strawberry as root?

justanotherbody commented 2 years ago

I'm running it in a konsole terminal within the KDE Plasma session (which I assume is X11 but ... maybe it's something else?)

I'm starting it as my user (miker)

EDIT: I would have sworn I tried running it through krunner and it failed but now that I try again it succeeds. Maybe the previous attempt was before I installed libxkbcommon-dev

Doh. Thank you for your time
