error while using classifychars about train-ocr

[lichenguang302]

hi @jamesawyer
which system do you use? windows or linux?
how can you use the openalpr-utils-classifychars program?
i am a python developer, looks like it should be compiled with c++, then i can use this tool,
but i am not familiar with c++
can you give some advice?
thank you very much!
