Compile for OSX

Compile the following linux code for Mac OSX. /* * HP TC1100 Touchscreen Enable * Copyright (c) 2004 Hewlett-Packard Co. * * Compile with `cc -O2 -o tc1100ts tc1100ts.c', * and run as root with `./tc1100ts'. * * This standalone program enables the Serial Port 1 * (SP1) of the NS LPC Super I/O, where the Wacom * Digitizer is connected to on the HP TC1100 Tablet PC. * * The serial device is mapped to 0x3e8 IRQ0-4 to match * the default /dev/ttyS2 port and IRQ mapping on Linux. * * To proof that the Wacom Digitizer is enabled by this * standalone, do the following: * - Change to superuser mode, i.e. root * - setserial /dev/ttyS2 * it should return: * /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 * - ./tc1100ts * - setserial /dev/ttyS2 autoconfig * - setserial /dev/ttyS2 * now returns: * /dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 4 * */ #include <stdio.h> #include <unistd.h> #include <sys/io.h> #include <stdlib.h> const int cfgindex = 0x4e; const int cfgdata = 0x4f; #define wsio(i,d) {outb(i,cfgindex); outb(d,cfgdata);} int main() { /* Get access to the ports */ if (iopl(3)) {perror("iopl"); exit(1);} // See the SuperIO Specificatio for details of each register wsio(0x07,0x03); // Select Logical Device - Serial Port 1 wsio(0x30,0x00); // De-activate Logical Device wsio(0x60,0x03); // I/O Port Base [15-08] wsio(0x61,0xe8); // I/O Port Base [07-00] wsio(0x70,0x14); // Enables Wake-up on IRQ4 wsio(0x71,0x03); // Level IRQ Req, Hi priority wsio(0x74,0x04); // DMA Channel Select 0 - no DMA wsio(0x75,0x04); // DMA Channel Select 1 - no DMA wsio(0x30,0x01); // Activate Logical Device /* We don't need the ports anymore */ if (iopl(0)) {perror("iopl"); exit(1);} exit(0); } /* end of tc1100ts.c */
