My linker is crapping out on me, any idea?
#include <fstream>
#include <iostream>
int main(){
        std::ifstream("in");
        std::cout << "test" << std::endl;
        return 0;
}

gcc test.cpp

I love you!

It works, I'm so silly, except
/usr/local/bin/g++ and /usr/local/bin/gcc are both symlinks to
/usr/bin/colorgcc

So what gives? :)

I have a FAT partition mounted to my Programming/ folder and when I copy the executable there I can't run it. All the permissions are set.
But it says---> bash: ./a.out: Permission denied

Does Linux not have the ability to run programs from a separate partition?

Programs will get the path passed to them, so they can tell what filename you used to run them and thus produce the correct functionality. Quite a few Linux programs do this.

I'm not entirely sure about executing code but in my experience FAT does not store permissions with files unless it's set up to do so (which is a hack). You'll probably need to change some permissions in /etc/fstab to allow access to users less privileged than root.
