QtWebEngine Linux deployment problem
-
I have a program on Qt using QtWebEngine, which I compiled on Ubuntu. I need to run this program on other computers with Ubuntu.
I tried to run my program on the VM and on a real computer. I got the same result. The program does not start, but the console displays the following:Qt WebEngine ICU data not found at /home/username/Qt/Qt5.9.2/5.9.2/gcc_64/resources. Trying parent directory...

#! /bin/sh LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"lib" export LD_LIBRARY_PATH exec ./appnameqt.conf:
[Paths] Prefix=.The location of the files in the "appname" folder:
appname appname.sh qt.confThis folder also contains all the files and folders copied from the path /home/username/Qt/Qt5.9.2/5.9.2/gcc_64/ (I did this in order to understand that all the necessary files are exactly here).
/home/username/Qt/Qt5.9.2/5.9.2/gcc_64/ - this is the path by which I installed Qt in the system on which I compiled the program.What's wrong, why are there so many errors? I have all the files here, so I'm confused.
Thanks!

Hi,
You should give a shot to linuxdeployqt. It simplifies deployment of Qt based application.

Unfortunately linuxdeployqt does not fix this issue, tried the latest, still got:
FATAL:zygote_host_impl_linux.cc(182)] Check failed: ReceiveFixedMessage(fds[0], kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid).
I have the ICU data and libraries in the right location, e.g.
resources/icudtl.dat
resources/qtwebengine*.paktranslations/qtwebengine_locales/*.pak
Any ideas?
