Urgent Help Needed to build Linux distribution

@jsulm, i didnt found any libqxcb.so file in QT installation path. I found only libqxcb.so file and pasted in plugin folder but getting same error.

@jsulm sorry libqxcb.so i found but its giving me same error.

jsulm

@Ram_Thakkar77 Did you call the directory plugins or plugin? It should be plugins.

Ram_Thakkar77

@jsulm Its plugins.

jsulm

@Ram_Thakkar77 Keep in mind: libqxcb.so depends on other libraries. You can find out which libraries by calling:

ldd PATH_TO_LIBQXCB.SO

But don't pu all of them in your package, only those from Qt.
You will probably need libQt5XcbQpa.so.5 lib in your package as well.

Ram_Thakkar77

@jsulm Pasted above mentioned file but no luck. Getting same error.

Ram_Thakkar77

??.. Any suggestion??

jsulm

@Ram_Thakkar77 Did you put libQt5XcbQpa.so.5 and libQt5XcbQpa.so.5.7.1 in the directory where the script is?
Maybe somebody else has an idea?

Well everything looks fine to me. Perhaps OP should run through all the steps once again. Check xcb's dependencies. Also Not required but try setting QT_PLUGIN_PATH explicitly. That's all I can think for now.

Ram_Thakkar77

I already pasted libQt5XcbQpa.so.5 and libQt5XcbQpa.so.5.7.1 files in main directory as well as in plugins folder also. I also added QT_PLUGIN_PATH in .sh file and below is my .sh file code:

#!/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
export QT_PLUGIN_PATH=$dirname/plugins
$dirname/$appname "$@"

now the error is changed and here is the screen shot of error as well as my folder structure

@Ram_Thakkar77 According to the error QtWebEngineProcess is also required. Try copying it too. It is at location for eg.:
5.7/gcc_64/libexec/QtWebEngineProcess

Edit: Not sure of the first error.

Ram_Thakkar77

OMG, streching my hairs. After copying QtWebEngineProcess Now getting so many error:

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed.
Qt WebEngine ICU data not found at /opt/Qt5.7.1/5.7/gcc_64/resources. Trying parent directory...

Qt WebEngine ICU data not found at /root/Desktop/QTEXETesting. Trying fallback directory... The application MAY NOT work.

p3c0

@Ram_Thakkar77 Well I think you need to check this too.
http://doc.qt.io/qt-5/qtwebengine-deploying.html

Ram_Thakkar77

@p3c0, After reading above link i pasted all files mentioned in that pages to my directory but still getting same error. any other way around to solve this issue??

p3c0

@Ram_Thakkar77

Qt WebEngine ICU data not found at /root/Desktop/QTEXETesting. Trying fallback directory... The application MAY NOT work.

Did you deploy all the file as said here ?
http://doc.qt.io/qt-5/qtwebengine-deploying.html#deploying-resources

at path /root/Desktop/QTEXETesting

Ram_Thakkar77

I pasted all files in same path and here is the scree shot of same

@Ram_Thakkar77 Well it seems that the resources were found inside the application directory but there seems to be library incompatibility issues as seen the end.
Do you already have Qt installed at the default path on deployment machine ?
I'm too not sure which library is referring to older one. You just need to ldd to check if libraries from default path are referred.

Ram_Thakkar77

@p3c0, yes QT is installed on my machine but for testing purpose i just renamed QT folder. I just need to check that whether without QT folder its working or not??

p3c0

Try. You actually need to find out which new library is referring to default one.

Ram_Thakkar77

@p3c0, Actually i tried a lot but not managed to find out what is the actual cause. Its very urgent, i need to redistribute my qt made application to some one. So please help me out for this problem.

p3c0

@Ram_Thakkar77 Can you post output of ldd QtWebEngineProcess which is present in your application directory ?
