A Common Error

One of the most common errors that people make is the use of a series of spaces where a tab should be used. The correct form is as follows…


[ tab ] <ACTION>



  • In many cases cutting and pasting will produce some errors…
    • It will usually reproduce this tab as several spaces.
    • It may also break lines of text across several lines, depending on the editor, thus giving many unexpected errors.
      • Ex: a long line of comments may break to the next line, and the make utility will no longer ignore this line, as it should.


  • Many FTP programs will automatically replace this tab with spaces as well. So, if you want to FTP a makefile to your GL account you will probably need to correct this problem once the file is in your directory.
