qtcreator under WSL ubuntu throws an error

iwrwrc

i ve installed qtcreator using sudo apt install qtcreator

after installation

i run qtcreator command, and i have the output:

qtcreator: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

what can be the problem?

jsulm

@iwrwrc How was it installed in WSL?

iwrwrc

did first

sudo apt-get install qt5-default
sudo apt-get install build-essential
sudo apt-get install libfontconfig1
sudo apt-get install mesa-common-dev
sudo apt-get install libglu1-mesa-dev -y

and then

sudo apt install qtcreator

i didn't make the Set file association with pro files section as mentioned here https://wiki.qt.io/Install_Qt_5_on_Ubuntu tho

because, i could not found the .local folder...
.. is there a way to troubleshoot the problem?

libQt5Core.so.5 shared library is not found.
You can search manually for it to see whether it is somewhere.

iwrwrc

yes it's here. ive found it using apt-file

libqt5core5a: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
libqt5core5a: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.12
libqt5core5a: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.12.8

nsight-systems: /usr/lib/nsight-systems/Host-x86_64/libQt5Core.so.5

@iwrwrc Looks good. Try

ldd qtcreator

What does it output?

iwrwrc

@jsulm said in qtcreator under WSL ubuntu throws an error:

@iwrwrc Try to create a symbolic link /lib/x86_64-linux-gnu/libQt5Core.so.5 pointing to /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
For some reason libQt5Core.so.5 is in /usr/lib/x86_64-linux-gnu and other Qt stuff in /lib/x86_64-linux-gnu

iwrwrc

@iwrwrc said in qtcreator under WSL ubuntu throws an error:

it starts pointing to itself

SGaist

Hi,

How did you create the symbolic link exactly ?

iwrwrc

i did

ln -s /lib/x86_64-linux-gnu/libQt5Core.so.5  /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

had an output saying file does not exist. so i forced it using

ls -sf /lib/x86_64-linux-gnu/libQt5Core.so.5  /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

after this. every time i have a warning of too many levels of symbolic links.

My problem is now resolved using just this command

sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

jsulm

@iwrwrc It's (ln -s target link_name):

ln -s /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 /lib/x86_64-linux-gnu/libQt5Core.so.5

See "man ln".

@iwrwrc
Please take the time to read the manual page on a command if you don't know how to use it or it gives an error you don't understand, rather than just continuing blindly....

My problem is now resolved using just this command

sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

Wot?? We don't execute some command to alter a supplied file in a system area because we have some issue...! Restore this file immediately!

iwrwrc

Yes, thanks.I see that i confused between target and link name

iwrwrc

Ok, i'll try restore the file. and see if i can resolve the issue

iwrwrc

@JonB I have resotred it now.

and

ls -l /lib/x86_64-linux-gnu/libQt5Core.so.5
