calling ls and other using execve

I'm trying to create a simple program that will allow to execute basic shell commands. Problem is execve just hangs everytime.

Heres the code:

    char* arglist[]={"ls","-l",NULL};
    char* env[]={NULL};
    int status;
    while (1)
    {
        if (fork() != 0)
        {
            waitpid(-1, &status, 0);
        }
        else
        {
            execve(arglist[0],arglist,env);
        }
    }
    return 0;
}

The first arguments should be a full path to the binary you execute:

char* arglist[]={"/bin/ls", "-l", NULL};
