The compiler of Netbeans reads:
gcc -c -g -Wall -I/usr/openwin/include graphics.c
graphics.c:13:22: fatal error: X11/Xlib.h: No such file or directory
#include < X11/Xlib.h>
compilation terminated.
make.exe": * [graphics.o] Error 1"
Although there are questions asked about X11/Xlib.h on the site I found none which applies for Windows (as the existing solutions all just seem to work on Mac os). I am really new to programming, so any enlightenment is welcomed!
openwin? how old is the source you're trying to build? (and as BadZen says, it's not going to work on windows without some extra software) - John3136
