Compilation problem for tesseract 4.00.00

[Kazi Moinul Hossain]

Hi everyone,

I have installed leptonica 1.74.1 and then tesseract 4.00.00.

After that, i have created a C++ program stated below which ultimately will show the leptonica and tesseract version installed in the system.

#include<baseapi.h>
#include<allheaders.h>
#include <sys/time.h>

int main() {

tesseract::TessBaseAPI *myOCR = new tesseract::TessBaseAPI();
printf("Tesseract-ocr version: %s\n",myOCR->Version());
printf("Leptonica version: %s\n",getLeptonicaVersion());
return 0;
}

While compiling my code using following command

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

i am encountering following error,

//usr/local/lib/libtesseract.so: undefined reference to ‘pixReadFromMultipageTiff ‘

//usr/local/lib/libtesseract.so: undefined reference to ‘pixReadMemFromMultipageTiff ‘

collect2: error: Id returned 1 exit status

Again to mention, my tesseract version is 4.00.00 and leptonica version is 1.74.1.

Can anyone please help me to figure it out?

Thanks,

Kazi Moinul Hossain

It seems that your (leptonica?) installation is corrupted. Your example works for me (for 4.00 and 3.05):

zdeno@level2:~/test> g++ sample.cpp -o sample -llept -ltesseract
zdeno@level2:~/test> ./sample  
Tesseract-ocr version: 4.00.00alpha
Leptonica version: leptonica-1.74

You did not mention from where you installed leptonica and tesseract.

what info do you see when you type

tesseract -v

[Kazi Moinul Hossain]

Not every commands though, but i understood the what i did with the commands. Is there any flaw in my commands?

Zdenko

[ShreeDevi Kumar]

I use the following batch files in the folders where I have cloned tesseract and leptonica.

1. leptonica

#!/bin/bash

git pull origin

./autobuild

#./configure --disable-dependency-tracking 

./configure

make

sudo make install

sudo ldconfig

cd prog

make

cd ..

2. tesseract

#!/bin/bash

./autogen.sh

./configure 

LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make

sudo make install

sudo ldconfig

make training

sudo make training-install

[ShreeDevi Kumar]

Your problem could be that you have some old version of leptonica installed on your system. Uninstall and remove all old versions and then try.

Also you have not responded to zdenko's suggestion to provide output of 

ldd tesseract

or

ldd /usr/local/bin/tesseract

(use the location of tesseract, which you can find by

which tesseract)

[Kazi Moinul Hossain]

Thanks a lot shree! Is there anything more you did in the "src" and "prog" directory under leptonica folder like "make allheaders", "make xtractprotos"?

[ShreeDevi Kumar]

No.​

[Kazi Moinul Hossain]

I am reinstalling leptonica and tesseract and I will let inform afterwards.

[Kazi Moinul Hossain]

how can i uninstall old leptonica fully? I am attempting with "sudo apt-get autoremove leptonica" and it is showing "unable to locate package"

I uninstalled all the previous leptonica and tesseract, installed all the new stuffs. When i am typing tesseract -v, it is showing properly the leptonica and tesseract version. 

But When i am typing, tesseract sample.tif sample, it is showing "Illegeal instruction (core dumped)".

Ultimately, i became unable to compile the C++ program as mentioned here before.After compilation command, it is showing, "fatal error: baseapi.h: No such file or directory"

What could be the soultion? Please help

IMO there is only one solution if you want to start programming - take some course and learn something about your OS and programming - if you are not able to handle error  like "fatal error: baseapi.h: No such file or directory" by yourself, you are in troubles.

If are serious about programming you should also learn how to debug program e.g. find where (and maybe why) there is " illegal instruction(core dumped)".

Unless your tesseract installation is not working properly (at least with images in test folder) do not even think about trying your compile own program. There could be several reason for it, but you do not provide details, so it is no possibility to guide you.

Hi,
After long effort, i installed leptonica 1.74 and tesseract 4.00alpha. But here goes another problem.
When i am typing, "tesseract -v", i am getting the actual versions.

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

but when i am compiling 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.c -o smpl.out -I/usr/local/include/leptonica -I/usr/local/include/tesseract -llept -ltesseract

i am getting the following output.

Tesseract version 3.04.01
leptonica version leptonica-1.74

Can anybody please help me to help me figure out this?

[Kazi Moinul Hossain]

The code is

[Kazi Moinul Hossain]

Finally, i solved it. Now after compilation, i am getting the correct version of leptonica and tesseract.

Tesseract version 4.00.00alpha
leptonica version leptonica-1.74

I uninstalled libleptonica-dev and libtesseract-dev and again compiled. It ran with correct output.

Thanks everyone in this group :)
