  <p>It throws different errors with different thrax versions. I read a solution in this forum.</p>

  <p>It says openfst must be 'built' with <code>./configure --enable-far=true</code> . i uninstalled openfst and installed it using <code>./configure --enable-far=true</code> and also with <code>./configure --enable-far</code>. The error still persists. </p>
