Hi.  I was just testing alpr on a Raspberry Pi 2, and got this error:

% alpr -c eu webcam
Error opening data file /usr/share/openalpr/runtime_data/ocr/leu.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your 
"tessdata" directory.
Failed loading language 'leu'
Tesseract couldn't load any languages!
^C
% ls /usr/share/openalpr/runtime_data/ocr/
tessdata
% ls /usr/share/openalpr/runtime_data/ocr/tessdata/
lau.traineddata  lgb.traineddata  lkr2.traineddata  lus.traineddata
leu.traineddata  lkr.traineddata  lsg.traineddata
%

Is the hardcoded path to leu.traineddata wrong in the binary?

The problem seem to be similar to the one reported in
<URL: https://github.com/openalpr/openalpr/issues/641 >.

I was able to work around it by adding symlinks:

root@rpi2-buster:/usr/share/openalpr/runtime_data/ocr# ls
tessdata
root@rpi2-buster:/usr/share/openalpr/runtime_data/ocr# ln -s tessdata/* .
root@rpi2-buster:/usr/share/openalpr/runtime_data/ocr#
