问题现象
In Ubuntu 22.04 there is currently an open bug QtChooser doesnt support qt6.
So even if Qt6 has been installed using sudo apt install qt6-base-dev, qtchooser -l does not list a qt6 option and qmake outputs qmake: could not find a Qt installation of ''.
Assuming Qt6 is installed and qmake6 can be called, I believe there are two options:
解决方案
系统解决方案 1. Select Qt6 system-wide
- Generate
qt6.conf
based on the path toqmake6
bash
qtchooser -install qt6 $(which qmake6)
- Move/copy
qt6.conf
to system-wide dir
bash
# sudo mv ~/.config/qtchooser/qt6.conf /usr/share/qtchooser/qt6.conf
sudo cp ~/.config/qtchooser/qt6.conf /usr/share/qtchooser/qt6.conf
- Set Qt6 as default option
bash
sudo mkdir -p /usr/lib/$(uname -p)-linux-gnu/qt-default/qtchooser
sudo ln -sf /usr/share/qtchooser/qt6.conf /usr/lib/$(uname -p)-linux-gnu/qt-default/qtchooser/default.conf
当前用户解决方案 2. Select Qt6 for current user only
- Generate
qt6.conf
based on path toqmake6
bash
qtchooser -install qt6 $(which qmake6)
-
Select Qt6 as default (place in ~/.bashrc for persistence):
export QT_SELECT=qt6
