== Note on compiling HTK ==

Before compiling with "make all", please make the following changes in the code, for being able to handle longer context feature names.
The files we have changed are: HTKLib/HShell.h, HTKLib/HUtil.c, HTKTools/HHEd.c and if neccessary  hts_engine/hts_engine.cpp.

- '''in HTKLib/HShell.h'''  [[BR]]
{{{
  line 120:  #define MAXSTRLEN 256    /* max length of a string */ 
  changed to:
             #define MAXSTRLEN 2048   /* max length of a string */ 
}}}

- '''in HTKLib/HUtil.c''' [[BR]]
{{{
  line 1422:  char hname[256];
  changed to:
              char hname[MAXSTRLEN];
}}}

- '''in HTKTools/HHEd.c'''
{{{
  line 329:  CreateHeap(&hmmHeap,"Model Heap",MSTAK,1,1.0,40000,400000);
  changed to:

  line 8103:  CreateHeap(&questHeap,"Question Heap",MSTAK,1,1.0,8000,16000);
  changed to:
              CreateHeap(&questHeap,"Question Heap",MSTAK,1,1.0,8000,200000);

  line 8104:  CreateHeap(&tmpHeap,"Temporary Heap",MSTAK,1,1.0,40000,400000);
  changed to:
              CreateHeap(&tmpHeap,"Temporary Heap",MSTAK,1,1.0,40000,1600000);
}}}
[[BR]]

We have made another small change in the hts_engine/hts_engine.cpp for being able to use phoneme names like r=, (if you will not use the hts_engine you do not need to change this).

-  '''in /hts_engine/hts_engine.cpp'''
{{{
  line 359:  if (!isalnum(buf[0])) break;
  changed to:
             if (!isgraph(buf[0])) break;
}}}

After these changes you can continue as normal with "make all" and "make install".[[BR]]
