HO scaricato NEt beans 6.9.1 completo , ma al momento di utilizzare c/c++ ho notato mancassero i compilatori , come d a guida ho installato cygwin e si è aggiornato e installato perfettamente e anche netbeans la riconoscoiuto e impostato con compilatore c gcc e c++ g++
ho scritto un semplicissimo programma
ma
codice:
#include <stdio.h> 
#include <stdlib.h> 
int main() { 
printf("ciao"); 
scanf("\n"); 
return 0; 
}
ma dopo aver cliccato run le scritte sono le seguenti:

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
