For one reason or another, I am messing around with the exit() function in c++. I am getting all kinds of strange errors from my mac running lion (64 bit). I am compiling using g++ -o -g -Wall
.
Exhibit A:
#include <iostream>
int main(int arc, char *argv[]){
exit(1);
}
The Terminal output looks like this
$ g++ -o -g -Wall test main.cpp
ld: in test, can't link with a main executable for architecture x86_64
collect2: ld returned 1 exit status
but $ g++ -o test main.cpp
compiles fine.
using #include<stdio.h>
or #include<stdlib.h>
result in the same compilation error.
I am just wondering if anyone might be able to see immediately what is going on here?
test
is the name of the binary to produce, your first argument list should be:
> g++ -g -Wall -o test main.cpp
^^^^^^^ -o has test for an argument
-o is meant to be followed immediately by the name of the output file. It is probably trying to use your old binary 'test' as a source file, incorrectly.
Try this:
g++ -o test -g -Wall main.cpp
