make training problem #17

Hello! I'm trying to run the makefile with the test set provided in the directory without success. I created the .box filesm but the script end with this error when i run Make training:

combine_tessdata -u /home/tulipan1637/Documents/Emiliano/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.traineddata /home/tulipan1637/Documents/Emiliano/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo. Failed to read /home/tulipan1637/Documents/Emiliano/OCR/OCRtraining/ocrd-train/usr/share/tessdata Makefile:97: recipe for target 'data/unicharset' failed make: *** [data/unicharset] Error 1

I know it's a problem with my PATH but I don't really understand it. In that folder there are the .traineddata files.

In the OCR group i got this reply:

_You have some problems with your path configuration, check the error message:

Failed to read /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata

the path does not make sense. And also the command line:

combine_tessdata -u /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.traineddata  /home/tulip/Documents/Em/OCR/OCRtraining/ocrd-train/usr/share/tessdata /foo.

you probably also have a "blank" after "/usr/share/tessdata".

Bye

But I still don't understand why this happens, what do I have to modify in the Makefile to make it work?

Thank you!

It's a bug in the Makefile, there's a trailing space in the TESSDATA assignment. I'll fix it but I'm wondering why this hasn't happened to us. What platform are you on?
