Salve ragazzi, stò cercando di configurare correttamente Java Cup su Eclipse.
Ho installato il pacchetto di cup dal sito ufficiale, successivamente da eclipse ho fatto file new project Java Cup project e l'IDE mi ha generato un progetto in java cup.
Ho riscontrato già qui diversi problemi:
l'ide mi ha creato una classe java Driver.java dove all'interno c'è un Main, nel Main però è dichiarato ed usato un oggetto di tipo Parser, tale oggetto NON viene trovato all'interno del progetto(in sostanza mi dice importalo e mi da diverse scelte...ma nessuna utile)
Chiedendo un po in giro mi dicono che per prima cosa devo provare a compilare il file build.xml, quando però provo a compilare tale file mi vengono generati 100 errori di compilazione
Buildfile: C:\Users\Giordano Giammaria\Desktop\Compilatori\Esercizio4\build.xml
generate:
