I installed in the virtual machine ubuntu1804x64, compile mupdf are normal, qt using the command line to install 5.9.8
Sudo apt - get the install qt5 - default qtcreator, period of mistakes
Strangely, I use the official after the installation package to install qt5.14.2, then it turned regular after he compiled using 5.14 again, very strange, my actual target environment is domestic system of the Arm architecture, there is no official QT installation package, can only command line installation, anyone who can help me solve the problem? 300 is not enough in the
