cntraining fails when opening normproto file on windows. #611

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Run cntraining on windows

What is the expected output? What do you see instead?
cntraining fails, no normproto file is created

What version of the product are you using? On what operating system?
3.02

Please provide any additional information below.

in cntraining.cpp the function WriteNormProtos accepts a directory. In 
WriteNormProtos a check is done to see if directory is not null, if it is not 
then the contents of directory is prepended to the filename followed by a slash 
then the filename. On Windows at least, the directory is passed as a null 
string, so directory itself is not null but points to a null. This then means 
that a filename of "/normproto" is tried to be opened, which will fail. A check 
should be added to make sure that directory is not only not null, but also does 
not point to a null string.

There is also the issue that the language should be prepended to normproto as 
well, as combine_tessdata now seems to look for a file called 
"<lang>.normproto" not just "normproto"

under version 3.02, cntraining will generate normproto also generate 
traineddata - never failed so far - it is my personal experience. [OS=winXp]
will you please upload either  text file  or tif/box file for testing and 
feedback to you.

I saw a fix had gone in about a week ago that fixes this issue, so I'd say this 
can be closed. 

In fact here it is : http://code.google.com/p/tesseract-ocr/source/detail?r=674

I have the same problem. Tesseract crashes when reading .tr file on cntraining 
command. I made the 2 changes and it doesn't help. I use version 3.01 on win7.
