Trying to build Tesseract-ocr for Linux arm64 Ubuntu 16.04 on Nvidia Jetson TX2 development board

[Kyle Clinton]

Hello,

I have been trying to build from source the 4.0.0 rc2 and the release code bases for Linux arm64.  I have been trying to use it in conjunction with the javacpp project which has shell scripts for building both the Leptonica and Tesseract projects.  I received a bit of help when I submitted a bug because the make file was throwing an error and I was told that I had to run the autogen.sh script to fix the one issue where it was trying to compile in something that was no longer part of the project. 

I am now getting an error that seems to be that Tesseract is not able to find something that SHOULD be in the liblept.so

In this attempt I was back to trying rc2 but I had the same error on 4.0.0 release.

I am using leptonica-1.76.0 which seemed to build correctly after I update tiff package to tiff-4.0.10 because of an odd config.guess issue.

Has anyone else been able to make this build correctly for the Jetson TX2 even if it was not part of the javacpp build process?

I am guessing there is something wrong with my version of leptonica from the error but I am not sure what the next step is in tracking down and ultimately fixing my issue.

Many Thanks!

Kyle

seems like you build leptonica with jbg (jbig?) library but this library is not used for linking with tesseract...

Please provide all steps how you build leptonica and tesseract. 

Make use you use the latest code (leptonica and tesseract) - there are several fixes included...
