Hi guyz
my task is to write program which should work on AIX system, which draws a line on image(graphics).I wrote it in turbo c 3.0 under windows XP(i dont have AIX).Then i installed freebsd on another system.I copied myprogram.exe to that system and tried to run.Then i came to know that
1) Exe files are not identified in Unix
2) One OS made exe file doesnt run in other OS for eg i made myprogram.exe in windows which wont run in unix

So i selected gcc in my freebsd system and compiled myprogram.c which gives lot of errors.Conio and graphics.h doesnt work in gcc.for conio we can use curser.h but for grahpics.h i dont know.so how to overcome this problem.finally i should give my client a exe file which runs on AIX.any help.Thanks in advance
