Gantt dijagram i CentOS

Kako napraviti Gantt dijagram na CentOS6 mašini.
Prvo, šta je GanttProject :
GanttProject is an open source task and project management tool that can display Gantt charts and PERT. Home page : GanttProject homepage
Napomena : na početnoj strani je dobar video tutorijal osnovnih funkcija.
Šta sve može :
Create tasks and milestones. Aside from the start date and duration, every task may have priority, cost, and user-defined custom fields.
Organize tasks in a work breakdown structure. Hierarchical tree where progress, dates or costs of lower level tasks is summarized on the higher levels.
Draw dependency constraints between tasks, like “start X when Y finishes”.
Create baselines to be able to compare current project state with previous plans.
Na žalost GanttProject nema direktnu instalaciju za CentOS (ima za Ubuntu, grrrr).
Instalacija :
Hard prerequisite is having Java Runtime Environment installed.
Soft prerequisite is ability to run java executable from console.
Ovo se proverava sa :
$ java -version
java version “1.7.0_79”
OpenJDK Runtime Environment (rhel-2.5.5.3.el6_6-x86_64 u79-b14)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
*******
Spustiti ZIP arhivu.
OBAVEZNO raditi u GUI okruženju!
# unzip ganttproject-2.7-r1891.zip
Ući u novonapravljeni folder (obavezno pročitati readme!!!).
# ./ganttproject
Ovo otvara prozor za GanttProject u GUI okruženju.
Dobar GanttProject zip install.
Pokretanje aplikacije :
Pokretanje iz GUI-a zahteva da se dođe do fajla, i on u svojim “Properties” mora imati obeleženu stavku “Permissions/Execute”.
Pokretanje iz komandne linije bi trebalo raditi kao nalog sa kojim se koristi GUI (u mom slučaju “velda”) :
$ ./ganttproject
A ako hoćete (kao ja) da imate link na desktop-u ka programnu, to se radi ovako :
# ln -s /home/velda/Gantt/ganttproject-2.7-r1891/ganttproject /home/velda/Desktop/
I onda, kada se klikne na fajl, potrebno je odabrati opciju “Run”.
