Qt installation is missing libxcb

[JoeCFD]

@JonB "error while loading shared libraries: libxcb-icccm.so" clearly shows what is missing.

install libxcb-icccm4.

@JoeCFD LOL, I didn't look at the error message :)
[You should restore your post. I think you were correct :) ]

[JoeCFD]

@JonB I restored it after I made sure I have this one in my computer.

[mzimmers]

@JoeCFD I tried that command, and I get the same "package not found" error.

I'm looking at the list on the page that @JonB referenced. I don't want one of the -dev packages, though, do I?

EDIT:

This page returned a long list, too, but might the first entry be the one I want?

@mzimmers -dev has include files which you do not need. You need them only when your app uses these libs directly. Therefore, install libxcb-icccm4 is good enough.

run command:
locate libxcb-icccm.so

to see if it is installed and where it is located.

@JoeCFD said in Qt installation is missing libxcb:

OK, that's what I thought...thanks. Though I will need to build my own Qt libraries from source (this is ultimately for an embedded system), so I guess eventually I will need one of those.

run command:
locate libxcb-icccm.so

to see if it is installed and where it is located.

That command returned nothing (which I expected).

I imagine that one of the packages returned in the search above is what I want; I just don't know which one.

@mzimmers
is your OS Ubuntu?
If yes, run
sudo synaptic
click find icon and type libxcb-icccm4
you will be able to see it. Then select it and install. You can see if it is installed or not.

@JoeCFD handy stuff to know...thanks.

So, after I installed libxcb_icccm4, I got a similar error for _image, then for _keysyms. I can go through these one at a time, but...is there a "superset" package that will save me the work?

[JoeCFD]

@mzimmers Maybe it is better to install them one after another. Otherwise, you may install a lot of things which are not needed.

For anyone who may happen to need this information, here are the xcb libraries I needed for Qt 6.5.2:

• libxcb-icccm4
• libxcb-image
• libxcb-keysyms
• libxcb-render_util
• libxcb-xinerama
• libxcb-xkb
  plus:
• libxkbcommon-X11

I ran into problems installing these with apt (it couldn't find the first one), but the Synaptic application @JoeCFD mentioned worked fine.

sudo apt install synaptic

Thanks to everyone for the help.
