Tesseract 4.00.00alpha compilation

Question

I installed tesseract 4.00.00alpha and leptonica in ubuntu 16.04 x86. When i am using the following command,

tesseract -v

The output is

tesseract 4.00.00alpha
 leptonica-1.74
  libjpeg 8d (libjpeg-turbo 1.4.2) : libpng 1.2.54 : libtiff 4.0.6 : zlib 1.2.8

 Found AVX
 Found SSE

Which is desired.

But while i am trying to compile my following code,

#include<baseapi.h>
#include<allheaders.h>
int main(){
tesseract::TessBaseAPI *first=new tesseract::TessBaseAPI();
printf("Tesseract version %s\n",first->Version());
printf("leptonica version %s\n",getLeptonicaVersion());
return 0;
}

with the command,

g++ sample.cpp -o sample.out -I/usr/local/include/leptonica -I/usr/local/include/tesseract -llept -ltesseract

The output is,

Tesseract version 3.04.01
leptonica version leptonica-1.74

Why the previous tesseract version is being shown? Is there any problem with the library files of tesseract and leptonica? Thank you!

Can you share how did you solve the problem? – thewaywewere Mar 25 '17 at 18:05 — thewaywewere, Mar 25 '17 at 18:05

The problem was while installing leptonica 1.74, i used a command,

sudo apt-get install libleptonica-dev

and while building tesseract 4.00.00 from source, i used a command,

sudo apt-get install libtesseract-dev

These above two commands are creating the problem. Actually we dont need install libleptionica-dev and libtesseract-dev since you are building tesseract from source.

I uninstalled both packages and reran my code.

sudo apt-get remove libleptonica-dev libletesseract-dev

It then worked successfully.

Thanks for your sharing – thewaywewere Mar 28 '17 at 11:02 — thewaywewere, Mar 28 '17 at 11:02
