Cannot get any query output from executable "/opt/Qt/6.2.2/gcc_64/bin/qmake"

@Jorge_Adan centOS7 could be the issue. You may try to build it from Qt source. Or upgrade centOS to the latest.

I installed again and ignored the error that I posted earlier.
After installing6.2.2again, upon trying to run QtCreator, I receive the following error:[devuser@localhost ~]$ ./Qt/Tools/QtCreator/bin/qtcreator ./Qt/Tools/QtCreator/bin/qtcreator: error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directoryI do have that library...

@Jorge_Adan You might not set /home/devuser/Qt/6.2.2/gcc_64/lib to LD_LIBRARY_PATH

@JoeCFD Yes, I've tried that. I receive the same error.
@Jorge_Adan You might add it to the wrong spot. Can you please tell how you added it? Also show the full list of your home dir by command ls -al.
Normally you do not install third party in /home/devuser/. Instead, install them under somewhere like /opt/thirdParties which is user name independent.First thing, try this on your terminmal:
export LD_LIBRARY_PATH=/home/devuser/Qt/6.2.2/gcc_64/lib:$LD_LIBRARY_PATH
./Qt/Tools/QtCreator/bin/qtcreatoryou also need to add /Qt/Tools/QtCreator/bin and /home/devuser/Qt/6.2.2/gcc_64/bin to PATH
Check your gcc version by
gcc --version
I believe it is 4.8.5 which can not support Qt 6. Qt 6 needs C++17 -

export PATH=$HOME/Qt/Tools/QtCreator/bin/:$PATH:.:
then your installed one will be in front of /usr/bin/qtcreatoryou need to do the same thing for LD_LIBRARY_PATH. There is order problem here. PATH settings decide which one will be looked for or executed first. It is important to know this since you have different Qt installations.

@Jorge_Adan said in Cannot get any query output from executable "/opt/Qt/6.2.2/gcc_64/bin/qmake":
[devuser@localhost ~]$ gcc --version

gcc 10.1.0 may be good enough for Qt 6. Good luck! -

@JoeCFD Yes, I already had my PATH setup like that.

@Jorge_Adan show ldd /home/devuser/Qt/Tools/QtCreator/bin/qtcreator
qtcreator uses relative path for qt libs. -
@JoeCFD Yes, I already had my PATH setup like that.

See the discussion now going on in https://forum.qt.io/topic/132610/qtcreator-6-0-can-t-start, I think it's same as yours?
