Urgent Help Needed to build Linux distribution

@jsulm , i tried above mentioned solution but no luck yet. Below is the code which i used in .sh file and .pro file:
#!/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 "$@"my .pro file code

@Ram_Thakkar77 You don't need the rpath line at the end of your pro file if you use the script to start your app.
What is the problem now with this script? -

What is the problem now with this script?Thanks for prompt reply. Let me remove the rpath from .pro file and check. Will get back to you very soon.

@jsulm , i remove that last file from .pro file and build new executable, after running .sh file i m getting below error:
'/root/Desktop/QTEXETesting/QTBrowser.sh' /root/Desktop/QTEXETesting/QTBrowser: error while loading shared libraries: libQt5WebEngineWidgets.so.5: cannot open shared object file: No such file or directoryI already pasted all .so files in same folder where my .sh file.
any suggestion.
-
@Ram_Thakkar77 As a simple test, just copy all the Qt libraries onto the deployment machine, keep the executable in the same directory, set the library path and try executing the application directly without any script. If it doesn't work, check the output of
lddon the application binary. -

@Ram_Thakkar77 Is libQt5WebEngineWidgets.so.5 in the same directory as the script? Can you start your app manually from command line after entering the directory where it is? Do you get the same error then?
NOTE: after changing pro file you need to rerun qmake and rebuild completely!

I already built new one , checked with ldd command and pasted all dependency in same folder where my .sh file but still getting same error.
below is the link of screen shot of same :

@Ram_Thakkar77 It is clear from the screen-shot that you are not exporting the correct library path. Also
lddwould have already shown the error and you would have noticed it. -

Screenshot@Ram_Thakkar77 So, you put all libs in lib subdirectory?
Then you need to change the script: LD_LIBRARY_PATH must contain the directory where the libs are.LD_LIBRARY_PATH=$dirname/libAlso, why is Makefile there? It is only needed to build the software.

@jsulm Really very sorry by mistake uploaded wrong image and corrected that link. Please check it once again.
@Ram_Thakkar77 Copy symbolic links as well, like: libQt5WebEngineWidgets.so.5, which points to libQt5WebEngineWidgets.so.5.7.1. Your app links against libQt5WebEngineWidgets.so.5 not directly against libQt5WebEngineWidgets.so.5.7.1, so you need those links (as alternative you can rename the libs like: libQt5WebEngineWidgets.so.5 --> libQt5WebEngineWidgets.so.5.7.1).

@jsulm, you are the savior for me. I pasted all .so files in same directory. Now its not giving error which i was getting previously. I m getting some new error like:
/root/Desktop/QTEXETesting/QTBrowser: /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5: no version information available (required by /root/Desktop/QTEXETesting/libQt5WebEngineWidgets.so.5)and here is the link for screen shot of same : Screen Shot

@Ram_Thakkar77 You did not copy all needed libraries! For example libQt5Core.so.5.7.1 is missing: you only have the link libQt5Core.so.5. Please make sure you really have all libs and symbolic links there.

I still have doubt if library path is set correctly because the system is referring to libraries in
/usr/libwhere as it should have been the new path.@p3c0 You're right! I didn't notice this.
@Ram_Thakkar77 in the screen-shot you posted you can see that the system tries to load Qt libs from /usr/lib. Check your script, putecho $LD_LIBRARY_PATHafter export LD_LIBRARY_PATH and post its output.

@jsulm, here is the screen shot of
echo $LD_LIBRARY_PATHand its showing correct path.

Screen shot@Ram_Thakkar77 Can you do this simple test?
- From terminal navigate to the directory where the app binary and libraries are present
export LD_LIBRARY_PATH=/root/Desktop/QTEXETesting:$LD_LIBRARY_PATH- run binary as
./QTBrowser
Post the output if you get any errors.

@Ram_Thakkar77 Plug-ins are missing. From the link I posted before:
"When looking for plugins, the application searches in a plugins subdirectory inside the directory of the application executable"
Did you create "plugins" subdirectory" and put needed plugins (like xcb) there?
