Okay, I know I'm a bit off-topic here, but if you can help, that'd be
great. I don't understand this warning:
[shell]
$ arm-elf-gcc -g -c -Wall -o obj/test.o test.c
test.c: In function `main':
test.c:6: warning: implicit declaration of function `abs'
[/shell]
[test.c]
#include <stdlib.h>
int main(int argc, char *argv[])
{
int a = abs(-3);
return a;
}
[/test.c]
Thanks.
