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...

Thanks! -
Hi and welcome to devnet,
Not a direct answer but did you consider using the linuxdeployqt project for that ?
Hope it helps

Thanks!I found the code for QtWebEngine (https://github.com/qt/qtwebengine/blob/5.11/src/core/web_engine_library_info.cpp). Here I found a function icuDataPath() that returns the path to the ICU date, or outputs an error. This function completely matches the output sequence with what is output from me, except for the part in which is
QLibraryInfo::location (QLibraryInfo::DataPath) % QLatin1String ("/resources");The fact is that I output my QLibraryInfo::location (QLibraryInfo::DataPath) before the program was crashed and it is
/home/new_username/Downloads/appname/lib
, that is, that way, I went and put the resource folder, but since I have a conclusion
/home/new_username/Downloads/appname/lib/libexec
it should be assumed that my QtWebEngine for some reason takes the meaningQLibratyInfo::location (QLibraryInfo::LibraryExecutablesPath) % QLatin1String ("/resources");which corresponds to this path. I think that this is a bug in the QtWebEngine code.
If I move the resources folder to
/home/new_username/Downloads/appname/lib/libexec
, then some of the errors are lost. I think this solution is a solution for a part of the problem.Now the application displays only the following at run:

Thanks!@MazyCrazy Is you issue fixed? I am facing a very similar issue. It works on certain version of Linux but have the same error as what you have on other Linux.
