[SOLVED] QT Deploy : This application failed to start because it could not find or load the Qt platform plugin "xcb" in "".

DendyGema

i'm using Ubuntu 14.04.10 with QT 5.6
i have been create my .deb with dpkg-deb --build MyApp
when i install it on another ubuntu 14.04.10 but without QT
i cannot execute my application ..

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

my library on /usr/lib/x86_64-linux-gnu/qt5
my libqxcb.so on /usr/lib/x86_64-linux-gnu/qt5/platforms and /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms

Hi, try putting the .so files that the plugin libqxcb.so needs together with it in the same platforms directory, they are:

libQt5XcbQpa.so.5
libQt5DBus.so.5

Also see same discussion here

DendyGema

like this ..??

Aborted (core dumped)

i add on my .pro

unix:QMAKE_RPATHDIR = /usr/lib/x86_64-linux-gnu/qt5
unix:QMAKE_LFLAGS += -Wl,-rpath /usr/lib/x86_64-linux-gnu/qt5

and on my main.cpp

QApplication::setLibraryPaths(QStringList("/usr/lib/x86_64-linux-gnu/qt5"));

this is my myapp.sh

 #!/bin/sh
 appname=`basename $0 | sed s,\.sh$,,`
 
 dirname=`dirname $0`
 tmp="${dirname#?}"
 
 if [ "${dirname%$tmp}" != "/" ]; then
 dirname=$PWD/$dirname
 fi
 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/qt5:${LD_LIBRARY_PATH}
 export LD_LIBRARY_PATH
 $dirname/$appname "$@"

help me please TT_TT

hskoglund

Hi, it should work if you get the RPATH set ok, I think you need to add a comma and quote it, like this:
unix:QMAKE_LFLAGS += -Wl,-rpath,"/usr/lib/x86_64-linux-gnu/qt5"

(Same for your QMAKE_RPATHDIR)

Also what you can do, you can tell Qt where your libqxcb.so is, by using the command line switch -platformpluginpath when launching your app:

./myapp.sh -platformpluginpath /usr/lib/x86_64-linux-gnu/qt5/platforms

Edit: forgot to say: for the above -platformpluginpath switch to work, you need to throw away the quotes in your myapp.sh file, like this:

$dirname/$appname $@

or you can just edit the file:

$dirname/$appname -platformpluginpath /usr/lib/x86_64-linux-gnu/qt5/platforms "$@"

this problem is SOLVED ,, but maybe anybody can give me a suggestion ^_^

this is my myApp.dbp

this is my myapp.sh

 #!/bin/sh
 appname=`basename $0 | sed s,\.sh$,,`
 
 dirname=`dirname $0`
 tmp="${dirname#?}"
 
 if [ "${dirname%$tmp}" != "/" ]; then
 dirname=$PWD/$dirname
 fi
 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:${LD_LIBRARY_PATH}
 export LD_LIBRARY_PATH
 $dirname/$appname "$@"

this is my qt.conf

[Paths]
Prefix=/usr/lib/x86_64-linux-gnu
Libraries=/usr/lib/x86_64-linux-gnu

i add some code on my myapp.pro and main.cpp

[myapp.pro]
CONFIG += release
unix:QMAKE_RPATHDIR = "/usr/lib/x86_64-linux-gnu"
unix:QMAKE_LFLAGS += "-Wl,-rpath /usr/lib/x86_64-linux-gnu"

[main.cpp]
QApplication::setLibraryPaths(QStringList("/usr/lib/x86_64-linux-gnu"));

Thanks all ..
