compile error under ubuntu 14.04

[Shree Devi Kumar]

​Srirangaji tried to build the current git source on ubuntu 14.04 and it is getting an error. 

I downloaded the same version and am able to compile clean on windows8 under msys2.

----------------------------

Here is the difference in the make.log where the errors occur:

On Ubuntu 14.04

mv -f .deps/tesseract-tesseractmain.Tpo .deps/tesseract-tesseractmain.Po

/bin/bash ../libtool  --tag=CXX   --mode=link g++  -std=c++11   -o tesseract tesseract-tesseractmain.o libtesseract.la   -lrt -llept -lpthread 

libtool: link: g++ -std=c++11 -o .libs/tesseract tesseract-tesseractmain.o  ./.libs/libtesseract.so -lrt -llept -lpthread

./.libs/libtesseract.so: undefined reference to `l_generateCIDataForPdf'

Any suggestions on how to fix this?

Thanks,

This error comes from Leptonica 1.70. Tesseract now requires Leptonica 1.71.

Leptonica 1.71 can be installed manually (but not so easily) and will ship with 

Ubuntu for their 14.10 release scheduled for October 23 of this year.

Thanks, Jeff.

Zdenko also indicated in a private email that Sriranga Ji may have another (older) version of leptonica. 

He does have Leptonica 1.71 as compiled by him recently as well as reported by tesseract version that he compiled in May. 

dell14-04@dell1404-OptiPlex-330:~$ tesseract -v
tesseract 3.03
 leptonica-1.71
  libjpeg 8d : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8

​I will ask him to check regarding this.

Shree​
