Yes, font_properties is missing but this is not an excuse for a crash.

Do I have to repeat that this gives a CRASH ! .... on Windows it will open the 
Close/Debug dialog and block  the process. This is something unacceptable, 
especially for automation.

Unacceptable is not following instruction ;-).

There is reason why there is assert [1]. If you do not like it - read that 
article there are an instructions how to avoid it. But than do not post issues, 
that tesseract produced wrong output, not working language data etc...

If you do not like CRASH you should call to Microsoft or compiler developers 
(because on linux there will be crash too).

did you create the font_properties file ?
if yes
so the solution is 
you have to rename your eng. counter.exp0.tr in to <font>.tr
and it work for me (i do have 1 tr file in my folder such as 
handwritten.pich.01.tr)

ex.
handwritten.pich.01.tr -> pich.tr

and the font_properties file is 
pich 1 0 0 0 0

in your case , you have 2 tr files right ?
and i didn't know how to combine it too - -''

best regard

Someone resolved this problem? I met this error too, and I used the full name, 
error msg is as below:

Reading test.kkk.001.tr ...
test.kkk.001 has no defined properties.
!"Missing font_properties entry is a fatal error!":Error:Assert failed:in file 
..\training\mftraining.cpp, line 281

And I had read the source code, but can't get that well, maybe this section 
code can not work as the normal way:

    if (font_dot != NULL && exp_dot != NULL && font_dot != exp_dot) {
      short_name = new_dup(font_dot + 1);
      short_name[exp_dot - font_dot - 1] = '\0';
    }

Could somebody help ?

thanks very much!

I'm facing this problem too. Anybody resolve it? This is holding up a project 
of mine. I've basically been trying to use mftrainig with the sample arial file 
they have posted in the downloads.

Is the font_properties  file supposed to have a single line in it? The 
documentation would suggest multiple, perhaps one line per tr file? Or is it 
per character entry in the tr file? What is it exactly?

Well if you do not post your files - nobody will help you.
If you do not follow instruction than it is your problem ;-)
