You have to include <stdbool.h>
in your program. bool
is actually a macro defined in stdbool.h
header file.
error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before function_name

Here is the error:
msp430-gcc -mmcu=msp430g2553 -Os -c -o gpio_test.o gpio_test.c
In file included from msp430_lib.h:9:0,
from gpio_test.c:4:
gpio_api.h:20:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘gpio_init’
gpio_api.h:27:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘gpio_ioctl_pull_en’
gpio_api.h:35:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘gpio_write’
make: *** [gpio_test.o] Error 1
Here is the header file where the error is coming from(The line numbers don't match up because I stripped all the comments out of the file to shorten it):
/* gpio_api.h - General Purpose Input/Output API
*/
#ifndef MSP_GPIO_API_H
#define MSP_GPIO_API_H
#include <msp430g2553.h>
#define INPUT 0
#define OUTPUT 1
#define DOWN 0
#define UP 1
bool gpio_init(int port, int pin, int direction);
bool gpio_ioctl_pull_en(int port, int pin, int direction);
bool gpio_write(int port, int pin, int value);
int gpio_read (int port, int pin);
#endif
It seems simple enough, yet I can't figure out what my problem is.
