Unable to load library 'tesseract': libtesseract.so: cannot open shared object file: No such file or directory
I've had tesseract and Tess4J running on my MBP for a while now. Today I started to migrate my app to the server and started installing everything on the server. Prior to running Tess4J in tomcat I tried to run a simple java program to make sure everything is fine and dandy. It's not...
- I'm on a centOS 64bit server
- I've installed tesseract and its working fine - tesseract myimage.jpg mytext produces data
However, running my simple class that useses Tess4j produces this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'tesseract': libtesseract.so: cannot open shared object file: No such file or directory
What I've done so far
- I've ran sudo ldconfig after installing tesseract
- I've search for libtesseract.so and its found in /usr/local/lib/libtesseract.so
Folder on server contains these files:
myimge.png ghost4j-0.3.1.jar jai_imageio.jar jna.jar maslab.jar pngj.jar tess4j.jar TesseractExample.class TesseractExample.java
tesseract -v produces:
tesseract -v tesseract 3.02.02 leptonica-1.69 libjpeg 6b : libpng 1.2.49 : libtiff 3.9.4 : zlib 1.2.3
How can I make Tess4J aware that libtesseract.so does exist?enter code here
I had this problem too.
Did you run the following after installing tesseract:
That fixed it for me.
You must set LD_LIBRARY_PATH environment variable to the path where libtesseract.so is.
Maybe it is a 32 bit library .so installed.
It is necessary to define the variable jna.platform.library.path. For instance:
