Required minimum Qt 5.7 shared libraries (.so) for Linux deployment

lindevs

I read this http://doc.qt.io/qt-5/linux-deployment.html article about Qt deployment for Linux. I've seen if I want to deploy my application for Linux I need include the following files:

myapp
myapp.sh
platforms\libqxcb.so
libQt5Core.so.5
libQt5Gui.so.5
libQt5Widgets.so.5

But If I include these Qt .so files my application isn't run. So I need to know what Qt 5.7 shared libraries (.so) I need to include for minimal application, for example:

#include <QtWidgets/QApplication>
#include <QtWidgets/QMainWindow>

int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	
	QMainWindow window;
	window.show();
	window.setWindowTitle("Hello world");

	return app.exec();
}

I create myapp.sh based on article:

#!/bin/sh
appname=`basename $0 | sed s,\.sh$,,`

dirname=`dirname $0`
tmp="${dirname#?}"

if [ "${dirname%$tmp}" != "/" ]; then
dirname=$PWD/$dirname
fi
LD_LIBRARY_PATH=$dirname
export LD_LIBRARY_PATH
$dirname/$appname "$@"

I need full list Qt 5.7 shared libraries what I need include for this minimal application deployment. My application works well on a development environment.

hi and welcome

Cant you use ldd on the .exe to see which "so" it needs?

My fav site for deployment is
http://www.tripleboot.org/?p=536

I added missing libraries. I used ldd

libicudata.so.56
libicui18n.so.56
libicuuc.so.56

Now when I run myapp.sh I get error:

This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: xcb.

Why I get this error if I included:

platforms\libqxcb.so

hi
do ldd on the libqxcb.so also

I think that I found missing .so files. Thanks.

@lindevs
which was it ?

@lindevs said:

libqxcb.so

libqxcb.so depends on these .so files:

libQt5XcbQpa.so.5
libQt5DBus.so.5

So in my case project structure looks:

myapp
myapp.sh
platforms\libqxcb.so
libQt5Core.so.5
libQt5Gui.so.5
libQt5Widgets.so.5
libicudata.so.56
libicui18n.so.56
libicuuc.so.56
libQt5XcbQpa.so.5
libQt5DBus.so.5
