Best way to avoid this problems, effecient use of printf's and yes GDB would
have solved your prblem then.

Instead of printf("oops") go with perror(3) will prints cause of the error of the function
like this.
if ( ( fd = open (opcode, O_RDONLY ) ) == -1 )
perror("open Failed:");
this will print the error message prefixed with your message "open Failed"
man perror for manual.
