- Compilation with Linux Debian/Mint/Ubuntu
- Install required tools:
- apt-get install build-essential g++ make libbz2-dev zlib1g-dev libproj-dev libnova-dev nettle-dev libpng16-dev libjpeg-dev libjasper-dev qtbase5-dev qt5-default
- Compile zyGrib:
- Download file zyGrib-xxxxx.tgz on this page, and run these commands in a terminal:
- tar xvzf zyGrib-xxxxx.tgz
- cd zyGrib-xxxxx
- make install
- Command to run zyGrib from a terminal:
- Compiled version for Ubuntu
configuration of repositories
High resolution Worldmaps :
The script gshhs_maps2_cities_deb_install allow
to download and install high resolution Worldmaps which are not
in the main package in /opt/zyGrib/maps/gshhs
and more cities in /opt/zyGrib/data/gis
Script and packages by Dominique Hausser.
- Windows version
QT dll's included
Just unarchive where you will, (for eg. Desktop, home repository, USB flash drive, memory stick).
It is of course also possible to compile sources under Windows, after having
(version included in Mingw compiler is perfect).
Do not modify the structure of repositories.
Run zyGrib.exe, it's all.
- Mac OS X version (Intel)
Ready to use complete build:
- Mac version (PPC)
zyGrib must be compiled for your computer.
- Install the Apple development tools
and the libraries needed by zyGrib
(ask the forum for more precise instructions)
- Install XCode
- Install MacPorts
- Open a terminal and enter:
- sudo port install qt4-mac qwt-60 proj libnova zlib bzip2
- Download and uncompress zyGrib for Linux (sources)
- In a terminal, from zyGrib directory:
High resolution world maps GSHHS
The main package comes with 3 Resolutions (≈25 km, ≈5 km and ≈1 km).
You can add higher resolution maps (≈200 m and ≈100 m).
Be careful with low speed connection (due to the size of the archive).
Unpack maps in <...>zyGrib/maps/gshhs.
You don't need them, but it is so much nicer ...
Linux, Windows : zyGrib_maps2.4.tgz (100.8 Mo)
Mac OS X (Intel/PPC) : zyGrib_maps2.4_mac.dmg (103.1 Mo)
Additional cities lists
Data extracted from the database GeoNames
To be copied in directory
* Files come with zyGrib.
Loading a lot of cities can slow the program start.
