I'm a newbie to this, so I hope I don't sound too silly.
I'm trying to write a program in C that will let me turn on/off the data
lines on the printer port so I can drive external transistors/relays.
I've done this using Qbasic, but I can't get it to work in C. My
application must run it as an executable under Linux.
I've tried both the built-in compilers in SuSE linux (cc & gcc), and they
give me an error with the following code:
#define DATA 0x0378
#define STATUS DATA+1
#define CONTROL DATA+2
val1 = 0x81; /* 1000 0001 */
"undefined reference to 'outportb'"
I assume this is because there is no function called "outportb()". This was
a "standard" function back in my days of Borland Turbo C...
Can anyone help?
