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

@Jorge_Adan
Start by runningldd ./Qt/Tools/QtCreator/bin/qtcreator. Look through the output forlibQt6Core.so.6. Assuming from what you say that is does not say "file not found", look through all its dependencies and see whether one of them is not found. That can lead to the error message reporting it onlibQt6Core.so.6when in fact the issue is another file.I also note your output shows different versions of
libQt6Core.so.6.2.xin different places. I don't know whether the different versions is problematic. You can runlddon those too.@JonB Here is my output, using ldd:

You will have to await others to comment on your two lines in green. Maybe they are the issue, I don't know.
I am still a little unsure on whether thelibQt6Core.so.6 => not foundmessages are that that it cannot find that actual file or dependencies for it. You might like to look through the output paged intomore/lessinstead ofgrepping to understand just what it is telling you. -
@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...

@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 -

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":

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. -

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?
