Urgent Help Needed to build Linux distribution

[p3c0]

@Ram_Thakkar77 Can you do ldd on QtWebEngineProcess inside the script because that is where you export library paths and that is where we can find what QtWebEngineProcess uses.

[p3c0]

@Ram_Thakkar77 Are you sure this was after exporting new LD_LIBRARY_PATH because QtWebEngineProcess is using Qt libraries installed at default path and not your deployed libraries.

[Ram_Thakkar77]

@p3c0 I m really very for silly mistake here is my .sh file code and output which i got from terminal:

QtBrowser.sh 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

echo 'Start ldd of QtWebEngineProcess'
ldd $dirname/QtWebEngineProcess
echo 'Finished ldd of QtWebEngineProcess'

$dirname/$appname "$@"

[p3c0]

@Ram_Thakkar77 Sorry Im too out of options. May be some else can be of help from here.
I would suggest you to ask this question on the Qt mailing list.

[Ram_Thakkar77]

@p3c0 , Do me one favor. According my requirement can you suggest me how to make a qt application in fresh system?

Below are few points according my requirement:

1. Want to build linux executable using qtwebengine to play some html5 webgl content.
2. using same project if i can manage to play .mp4 video file then its huge advantage for me.
3. Need to distribute my qt app.

If require i will also take one fresh system and will install Qt on that system. So suggest me right direction for same.

[p3c0]

@Ram_Thakkar77 Actually no new suggestions as compared to older posts in this thread.
As said earlier you need to follow these 2 carefully:
http://doc.qt.io/qt-5/linux-deployment.html
http://doc.qt.io/qt-5/qtwebengine-deploying.html

If require i will also take one fresh system and will install Qt on that system.

That is a very good idea. Also please make sure you don't have any version of Qt already installed.

[Ram_Thakkar77]

@p3c0 I m using qt-opensource-linux-x64-5.7.1 version so is it okay or have to take another version?? Is there any sample application which i can try??

[p3c0]

@Ram_Thakkar77 Yes its fine.
You can try this example:
http://doc.qt.io/qt-5/qtwebengine-webenginewidgets-simplebrowser-example.html

[Ram_Thakkar77]

@p3c0 and @jsulm

Thanks a lot both of you for your throughout support. Unfortunately i didn't manage to short it out my problem. In future i will try again with QT. For time being i implemented work around solution with Google chrome and my client is also agreed with same. I liked QT very much but i think building linux executable is very tedious process compare to windows. So its my suggestion to QT teams that there must be a way to make it simple.

Thanks one again both of you.

[p3c0]

@Ram_Thakkar77 Don't give up just. Try asking it on the mailing list as said earlier.
I personally have never deployed any Linux application which included WebEngine so I might have fell short there. I have done other deployments which didn't use WebEngine and those worked according to the official Qt Linux deployment documents.
I'm sure you will get a solution on the mailing list.
Also there is an unofficial linux deployment tool named linuxdeployqt. Like androiddeployqt and windeployqt it should also fetch all the application dependencies and package them. Worth trying I guess.

[ambershark]

@Ram_Thakkar77 It sounds like you just don't understand linux properly. It isn't that it is harder than windows (and in a lot of cases it's actually easier), it's just that you don't understand how the program is run and how ld finds your libraries.

There's a term in windows called dll hell which I'm sure you've heard. You are basically just running into a similar situation in Linux but have no idea how it works or how to solve it.

I recommend you stick with it as once you figure it out it's quite easy. The info p3c0 and jsulm gave should have helped you get your distribution ready, but you kept missing libraries and not setting your custom LD path properly. If you do this correctly it is not only quite easy but can all be easily automated in a small bash script.

I definitely wouldn't blame Qt for this as you have a "distributing linux binary" problem, not a Qt one. That would have happened to you no matter what development toolkit you used. It has nothing to do with Qt at all.
