libqxcb.so doesnt find Qt libraries

[adutzu89]

So I managed to link my application to the correct libraries using qt.conf, but when I try to run it crashes because it cannot load the plugin, the plugin is found becaue I copied all plugins and it shows me the list as available.
When using

ldd libqxcb.so

ldd libqxcb.so

To copy to clipboard, switch view to plain text mode 

, it shows it's missing the Qt5 libraries but when using ldd against my executable it shows them as found.

Any ideeas why?

[adutzu89]

Can someone please explain to me how qt.conf works? I don't seem to understand the documentation page: http://doc.qt.io/qt-5/qt-conf.html, since the application still cannot find the libraries.

I want to use the deployed libraries stored in "libs" directory which is in <executable-directory>/libs.
I have added qt.conf to the resource system. Do I have to add it to a specific directory?(":/qt/etc/qt.conf", I don't understand what's with this path in doc page).

This is what my qt.conf has in it:
<RCC/>
[Paths]
Libraries = libs

I haven't used qt.conf myself, but yes, that's what the documentation says.
If you want to stored it in the resource system, it needs to be found under prefix "/qt/etc"

This is what my qt.conf has in it:
<RCC/>
[Paths]
Libraries = libs

Is that a mistype or does it really contain that XML-like tag at the beginning?

s that a mistype or does it really contain that XML-like tag at the beginning?

Made the file with the New Resource File option from QtCreator so I left it untouched, without it doesn't make any difference.

So, I tried the following variations for the directory tree:
<main-directory>/Executable
<main-directory>/lib
<main-directory>/platforms
<main-directory>/qml
<main-directory>/libexec
<main-directory>/qt.conf

<main-directory>/Executable
<main-directory>/platforms
<main-directory>/qml
<main-directory>/libexec
<main-directory>/qt.conf
<main-directory>/<all-required-libraries>

<main-directory>/Executable
<main-directory>/lib
<main-directory>/platforms
<main-directory>/qml
<main-directory>/libexec
<main-directory>/qt/etc/qt.conf

<main-directory>/Executable
<main-directory>/lib
<main-directory>/platforms
<main-directory>/qml
<main-directory>/libexec
<main-directory>/qt/etc/qt.conf
<main-directory>/qt.conf

The result is the same: libraries aren't found.

Which doesn't make sense, qt.conf is an INI file.

So, I tried the following variations for the directory tree:

You mean in the file system?

And with a correctly formatted qt.conf?

[adutzu89]

You mean in the file system?

<main-directory> is the directory containing the executable files and those paths are relative to that directory not to system root .

And with a correctly formatted qt.conf?

This what qt.conf contains:
[Paths]
Libraries = libs

[anda_skoa]

That looks all correct as far as I can tell.

What you could try instead is a different approach, i.e. with a start script that sets the LD_LIBRARY_PATH environment variable to include the directory where your Qt libs are.

[adutzu89]

Trying your option with LD_LIBRARY_PATH but it says

could not find or load Qt platform plugin "xcb"

[anda_skoa]

Does ldd on the plugin show the libraries as resolved now, when you run from an environment with the LD_LIBRARY_PATH set?

I have managed to advance another step after thet qt.conf failure I tried putting the libqxcb.so file inside plugins directory instead of platforms and forgot to change it back .
After changing back to platforms and using LD_LIBRARY_PATH I get the following issue:

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

This issue is existent both in Xubuntu 16.04.1 Virtualbox guest and on a laptop with Ubuntu 14.04.5.

Sounds like your Qt was built without OpenGL support.

Cheers,

Used the online installer, didn't built Qt myself.

[anda_skoa]

Hmm. Other OpenGL applications work on the target system?

It seems the cause of the QXcbIntegration issue was the fact that I wasn't loading the xcbintegrations plugin (didn't deployed it previously), neither I have read that I actually need to load other plugins except platforms(tough seems logical), I will give it another test deployment this evening after work.
It's strange tough, I remember putting it at one time and still didn't worked but probably I was missing something else(maybe the library dependency of the plugin at the time was not copied at the time the plugin was).

I'm facing another issue:
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
QQmlComponent: Component is not ready
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter

[adutzu89]

I was not deploying the Qml QtWebEngine module, just QtWebView that's why I got :

Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
QQmlComponent: Component is not ready
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter
QObject::connect: invalid null parameter

On a side note, my main laptop where I do the development loads the qt.conf but when I deploy the application on the guest virtualbox guest machine(which has an Xubuntu 16.04.1) the qt.conf file isn't loaded until I do a export of LD_LIBRARY_PATH with the path to my libraries.
