ocr-layout directory

[Bill]

Hi,
In my adventure with OCRopus I stumbled upon the contents of the ocr-
layout directory. I wanted to try out some page segmentation algorithm
implementations present there (besides RAST). I wanted to compile the
ocr-pageseg-wcuts.cc file, but got a lot of errors of missing var
types (probably because of wrong headers included)...
My question is - are the files located in the ocr-layout directory
meant to be there only for test purposes? Or is there a way to include
them in your own project...

Thanks in advance for your help,
Sending kind regards,

Bill

Ok, I've managed to narrow down the problem...
After issuing the following command in the ocr-layout directory:

g++ -o ocr-pageseg-wcuts ocr-pageseg-wcuts.cc -g
-I/usr/local/include/ocropus -I/usr/local/include/colib -I/usr/local/
include/iulib
-lpng -ljpeg -ltiff -locropus -liulib

I get the following error:

/usr/lib/gcc/i486-linux-gnu/4.3.3/../../../../lib/crt1.o: In function
`_start':
/build/buildd/glibc-2.9/csu/../sysdeps/i386/elf/start.S:115: undefined
reference to `main'
collect2: ld returned 1 exit status

Now this is something new, as it does not apply to OCRopus, but IMHO
to gcc...
Has anyone a clue?

Thanks in advance for your help,

Regards,
Bill
