Unless you want to compile softwares based on the old Qt 3, replacing ''qmake'' by ''qmake-qt4'' has no side effects. In any case, you can restore the initial state after installation is completed.

If ''qmake4'' or ''qmake-qt4'' refers to version 4.5.0, Qt is properly installed, you can return to the [[Installation:Linux#Lapack|installation of Geopsy softwares]].

Note that Geopsy package (3.5.0) is developed and tested with Qt 5.15.2 and Qt 6.5. Successful builds were reported with Qt 5.11. Error were encountered with Qt 5.9. If a sufficiently recent Qt is not available on your platform you can follow this tutorial to install binaries provided directly from Qt.

Downloading online installer

qt.io is a fancy commercial website but not really handy to get access to the open-source Qt package

  • Go to Qt
  • Click on "Download. Try. Buy" green button in the top right corner
  • Scroll down to "Download open source"
  • Scroll down to bottom of the page
  • Click on "Download the Qt Online Installer" green button
  • Select your platform and click on "Qt Online Installer for ..."

Great you have the file. Simple no?

Change permissions and run the installer

  • Change permission to be able to execute it (for Linux)
 $ chmod a+x qt-unified-linux-x64-4.0.0-online.run
  • And start the installer
 $ ./qt-unified-linux-x64-4.0.0-online.run
  • Under Windows, double-click on the .exe file
  • You have to create a Qt account (as simple as breathing, isn't it?), if you have already one enter your credentials.
  • Click on "Next"
  • Certify that you have read and approve the obligations of using Open Source Qt
  • Click on "Next"
  • You receive a great "Welcome", nothing to do
  • Click on "Next"
  • Make your choice if you want or not to send pseudonymous,... it is up to you
  • Click on "Next"
  • A very important step: select the destination path, choose it carefully. It is better to avoid moving or renaming it later on.
  • Select "Custom installation"
  • Click on "Next"
  • Select only these components:
 Qt
   Qt 5.15.2 (or higher)
 Developer and Designer Tools
   Qt Creator 9.0.1 (or higher)
   MinGW 8.1.0 64-bit (or higher)
  • Accept the license
  • Click on "Next"
  • Click on "Install"

Now the the real installation starts. It may last a little bit.

The final touch

Qt and the whole Qt Creator development environment is now installed.

 $ ls /path/you/chose/for/Qt
   5.14.2          dist  Examples             installer.dat       Licenses         MaintenanceTool.dat  network.xml  Tools
   components.xml  Docs  InstallationLog.txt  installerResources  MaintenanceTool  MaintenanceTool.ini  QtIcon.png

The interesting part of Qt is in folder 5.14.2 (or another version)

 $ ls /path/you/chose/for/Qt/5.14.2/gcc_64
    bin/          include/      mkspecs/      plugins/      translations/ 
    doc/          lib/          phrasebooks/  qml/ 

'qmake' building tool is in 'bin'. Add this path to your PATH

 export PATH=/path/you/chose/for/Qt/5.14.2/gcc_64/bin:$PATH

If you do not want to pollute your .bashrc, create a file "env" where you intend to build geopsypack:

 #!/bin/bash
 export PATH=/path/you/chose/for/Qt/5.14.2/gcc_64/bin:$PATH

Whenever you want to start building geopsypack, source this file.

 source ./env
