title: Error when generating a spell file in Vim: E484: Can't open file/tmp/tr.utf-8.spl
body: <p>I try to generate Turkish spell file for Vim from a word list with the following command:</p>
  
  <pre><code>mksp /tmp tr_TR.words
  </code></pre>
  
  <p><code>tr_TR.words</code> resides in <code>C:\Program Files\Vim\vim72</code></p>
  
  <p>Vim starts reading the word file but the process is interrupted before completion. Vim gives the following error message:</p>
  
  <pre><code>Compressed 5110514 of 6389213 nodes; 1278699 (20%) remaining
  Writing spell file /tmp/tr.utf-8.spl ...
  E484: Can't open file/tmp/tr.utf-8.spl
  </code></pre>
  
  <p>I use Gvim 7.2 on Win 7. The word list file <code>tr_TR.words</code> contains lines of words such as:</p>
  
  <pre><code>aba
  abaca
  abacası
  abacı
  </code></pre>
  
  <p>I couldn't find the cause of this error on internet. Do you have any suggestions?</p>
