=======================

WINDOWS INSTALL :

- Unzip previsat-4.0.8.1-exe-win32-64.zip and run the install setup.

NOTE : some browsers may detect PreviSat as a malware because the archive contains an executable file.

-----------------------

LINUX INSTALL (DEBIAN-LIKE DISTRIBUTIONS) :
- In the same directory of the PreviSat Debian archive, enter the following commands :
    sudo add-apt-repository ppa:rock-core/qt4
    sudo apt install -f ./previsat-4.0.8.1-bin-amd64-Linux.deb

-----------------------

MacOS X INSTALL :
- Open previsat-4.0.8.1-bin-x86_64-MacOS.dmg and drag-and-drop PreviSat on the Applications shortcut.


=======================

COMPILATION OF PREVISAT SOURCE CODE :

- Unpack the source package (for example tar -xfz previsat-4.0.8.1-src.tar.gz)
- PreviSat is developed with Qt 4.8.7 but its source code is also compatible with Qt 4.8.6 and certainly until Qt 5.5
- Specify the zlib directory (version 1.2.11 in preference) in PreviSat.pro (download zlib at http://zlib.net/ if you don't have it on your system)
- Compile the source code with Qt Creator (or run the following commands : make clean; qmake -config release; make). When compiled in release mode with GCC, there are no warnings (or very little) about PreviSat source code itself
- By default, PreviSat is in French language. To have it in English language, run lrelease in order to generate the compiled language file PreviSat_en.qm. To have PreviSat in other language, you have to specify the PreviSat_xx.ts in PreviSat.pro, launch lupdate and complete the PreviSat_xx.ts with linguist, and finally run lrelease to generate PreviSat_xx.qm

-----------------------

INSTALLATION OF PREVISAT AFTER COMPILATION :

To run PreviSat after the compilation, you need :
- Qt libraries
- zlib library (version 1.2.11 in preference)
- If you have generated it, a compiled translation file (must be in the same directory of executable)
- several directories specific to PreviSat :
    * doc  : contains user manual in pdf format (this directory must be in the same directory of the binary file PreviSat)

    * data : contains files necessary to PreviSat. This directory must be in your Data directories :
             -> LINUX PLATFORMS  :
                      <> Common Data directory : /usr/share/Astropedia/PreviSat/data for "stars" and "sound" sub-directories (and their own files; aos-default.wav and los-default files for "sound" sub-directory)
                      <> User Data directory : $HOME/.local/share/Astropedia/PreviSat/data for other sub-directories and their own files

             -> WINDOWS PLATFORM : C:\Users\<user>\AppData\Local\Astropedia\PreviSat\data (for Windows 7 and over)
             -> MacOS X PLATFORM : in the same directory of executable

    * tle  : contains TLE files (in the User Data directory for Windows and Linux; in the same directory of executable for Mac OS X)
