Unable to compile 3.04-rc1 under ubuntu 14.04

[grapemix]

The same issue is reported in https://code.google.com/p/tesseract-ocr/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&groupby=&sort=&id=1307

But the problem is still exists and the ticket is closed.

I got the error during compiling.

The error is:
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' ./.libs/libtesseract.so: undefined reference tol_CIDataDestroy'

tesseract -v
tesseract 3.03
leptonica-1.72

libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8

And here is the deb package I installed:
"autoconf",
"automake",
"libtool",
"libpng12-dev",
"libjpeg-turbo8-dev",
"g++",
"libtiff5-dev",
"libopencv-dev",
"libopencv-objdetect-dev",
"libopencv-highgui-dev",
"libopencv-legacy-dev",
"libopencv-contrib-dev",
"libopencv-videostab-dev",
"libopencv-superres-dev",
"libopencv-ocl-dev",
"libcv-dev",
"libhighgui-dev",
"libcvaux-dev",
"libtesseract-dev",
"git",
"cmake",
"build-essential",
"libleptonica-dev",
"liblog4cplus-dev",
"libcurl3-dev",
"python2.7-dev",
"tk8.5",
"tcl8.5",
"tk8.5-dev",
"tcl8.5-dev",
"imagemagick"

I basically follow the instruction in https://realpython.com/blog/python/setting-up-a-simple-ocr-server/

Please help. Thanks.

That error means that you are not linking against leptonica 1.72 library (but probably against some older version). It is not tesseract problem.

[grapemix]

Thanks for you quick response. My bad, I assume the lib will be ready after configure. Anyway, for the future reference, since we have to compile leptonica in ubuntu 14.04, we should use LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make instead of make.

Then the problem will be resolved.

Thanks.

Hi,
I am using tesseract-3.04.00 and for leptonica i tried both with 1.72 & 1.71.Still i get the below mentioned issue:-
./.libs/libtesseract.so: undefined reference to l_generateCIDataForPdf' ./.libs/libtesseract.so: undefined reference tol_CIDataDestroy'

Request help on this.

How did you resolve it?

Yes, how did you solve it @Sayanava ?

I removed previous 3.03 and re-install 3.04 from scratch. It works.
