Urgent Help Needed to build Linux distribution

p3c0

I still have doubt if library path is set correctly because the system is referring to libraries in /usr/lib where as it should have been the new path.

jsulm

@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, put

echo $LD_LIBRARY_PATH

after export LD_LIBRARY_PATH and post its output.

Ram_Thakkar77

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

jsulm

@Ram_Thakkar77 Please put missing libs (not only links!) in the directory as I said before. For example:

libQt5Core.so.5
libQt5Core.so.5.7.1

p3c0

@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.

jsulm

@p3c0 I think his problem is that some libs are missing in the directory like QtCore (he has only link there).

Ram_Thakkar77

@jsulm, all errors are gone related to links and necessary files after adding to respective folder, but now getting new error and below is the screen shot of same:

jsulm

@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?

Ram_Thakkar77

@jsulm, no i didn't create any plug in directory in that folder and from where i will find that xcb plugin.

jsulm

@Ram_Thakkar77 Well, you have to. Qt plug-ins are in "plugins" subdirectory of you Qt installation.

Ram_Thakkar77

@jsulm, i pasted plugins folder from Qt installation path and here is the screenshot of same:

jsulm

@Ram_Thakkar77 No need to copy the whole plugin folder from Qt!
Create empty plugins subdirectory and put libqxcb.so from plugins/platforms of your Qt installation there.

Ram_Thakkar77

@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?

p3c0

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.
