Multiple Qt profile directories

Question

Is there any way to change the Qt 5 profile directory in Linux (with both installed versions Qt: for desktop and android)? The second version tries to overwrite the config files with a permission denied message. I wish to have two different configs for both versions.

Answer 1

I think that you need to use qtchooser. I have highlighted the relevant information in the description taken from man page of qtchooser, below:

DESCRIPTION

Qt is a cross-platform C++ application framework. Qt's primary feature is its rich set of widgets that provide standard GUI functionality.

The Qt Chooser provides a wrapper to switch between versions of Qt development binaries when multiple versions like 4 and 5 are installed or local Qt builds are to be used.

It is commonly used via a symlink from an executable_name like qmake.

The answer to the question Qt5 installation and path configuration should help you.

Replace Default Qt version paths in /usr/lib/x86_64-linux-gnu/qtchooser/default.conf:

/opt/Qt5/bin
/opt/Qt5/lib

Check:

qtchooser -print-env

Reference: man qtchooser
