QTCreator 6.0 can't start

cyniu88

I took another computer (Windows 10) and installed ubuntu WSL but qtcreator does not start for the same reason :(

show ldd /mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/bin/qtcreator
on my machine qt creator uses relative path to find qt libs which come with it.

True. All qt libs are linked properly, but libQt6Core.so.6. I will take a look at it later.
ls -al /mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib/Qt/lib
to check if the libs are soft-linked properly.

libEGL.so.1 is not there as well.
https://forums.opensuse.org/showthread.php/518010-how-can-I-install-usr-lib64-libEGL-so

libxkbcommon.so.0 is missing as well.

Please make sure there is no invalid symlink named libQt6Core.so.6 somewhere in your LD_LIBRARY_PATH.

cyniu88

in my case it's look like:

cyniu@cyniu-PC:/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/bin$ ./qtcreator.sh

print LD_LIBRARY_PATH inside qtcreator.sh

/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib:/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib/qtcreator:/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib/Qt/lib:/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib/Qt/lib


print env after export LD_LIBRARY_PATH

./qtcreator: error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directory
cyniu@cyniu-PC:/mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/bin$

as you can see I just added some printouts inside the qtcreathor.sh script

I think it looks good, right?

@Christian-Ehrlicher said in QTCreator 6.0 can't start:

libQt6Core.so.6

locate libQt6Core.so.6 to check if there are duplicate libQt6Core

@JoeCFD said in QTCreator 6.0 can't start:

I don't understand,

what am I supposed to do?

JoeCFD

@cyniu88 locate is a command.
locate libQt6Core.so.6

You may need to reinstall qt creator. Link with relative path is broken. If you reinstall it and it has the same problem, it might be a Qt build problem. I will try it out at home to see I have the same problem.

cyniu88

locate libQt6Core.so.6

return nothing

I reinstalled QT many times, still the result is the same.
I took another PC (Windows 10 WSL Ubuntu 20) but qtcreator does not start for the same reason :(

on PC with DEBIAN qtcreatro 6.0 worsk well

JoeCFD

@cyniu88 Then try to use 6.0 one. Qt creator is stand alone. I will let you know if I have the same problem tomorrow.

find / -name libQt6Core.so.6

@Christian-Ehrlicher said in QTCreator 6.0 can't start:

...will be ghostly silent ;-) I think the OP should try

find / -name libQt6Core.so.6 -ls     ## or `-print` instead of `-ls` in the unlikely case your Linux doesn't accept it

cyniu88

comand "find" found only one place

There has been an on-going topic, unresolved so far, at https://forum.qt.io/topic/132524/cannot-get-any-query-output-from-executable-opt-qt-6-2-2-gcc_64-bin-qmake. It is to do with Qt Creator reporting unable to find libQt6Core.so.6 under Qt6. I have a feeling that topic and this are somehow the same issue? Maybe @Christian-Ehrlicher has a view?

I was confused there, and still am in this topic here, as to where exactly libQt6Core.so.6 => not found comes from. There are two possible ways get message

"error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directory

Either it actually cannot find a libQt6Core.so.6 file, or it can find the file but fails to load because of missing/incorrect dependencies. The error message then reports that case as "no such file" on the libQt6Core.so.6 it was trying to load.

Use ldd on existing libQt6Core.so.6 file(s) to determine whether they are loadable. Bear that in mind if you think the file should not be reporting "not found".

I do this a few posts above

@cyniu88
Yes, I see. I don't have access to Qt. If it's not huge output, can you post ls -l /mnt/f/LINUX-UBUNTU/QT/Tools/QtCreator/lib/Qt/bin, which is where qtcreator is.
