I am able to compile the ENGLISH version which is already in sample for tesseract but not able to add other language like ara.traineddata.

I am doing like

```
 Tesseract* tesseract = [[Tesseract alloc] initWithDataPath:@"tessdata" language:@"ara+eng"];

```

And it is recogninzing ENGLISH but for ara it is giving error

```
Error opening data file /Users/harshthakur/Library/Application Support/iPhone Simulator/7.0/Applications/3B0A1909-E1BA-45E9-99A0-FDEAB2CFF4E0/Documents/tessdata/ara.traineddata

```

Please make sure the TESSDATA\_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'ara'

any help will be greatly appreciated.
