What happens if you try to run the sample code at
https://github.com/bytedeco/javacpp-presets/tree/master/tesseract#sample-usage ?

[pigzee]

i run the sample code ,but the error is same with above.
remve os.classifier from pom.xml, only left

    <groupId>org.bytedeco.javacpp-presets</groupId>

[pigzee]

can javacpp-presets run in centos?

[saudet]

CentOS 6 or 7, yes, 5, no

[pigzee]

i solved the problem.
first, copy leptonica-1.73-1.2-linux-x86_64.jar and tesseract-3.04.01-1.2-linux-x86_64.jar to lib of your project in linux.
second, install gclib2.14 and gcc-4.8.0 in your linux, if your version is low.
it is ok.

but i don't know why that two jars can't build into package.

[saudet]

So, issues with the Maven plugin for Intellij. Make sure to let JetBrains know about that. I'm pretty sure It has nothing to do with glibc or gcc, or they would show up as errors in the exceptions above.

[pigzee]

thanks !

Adding that I encountered the same issue. Built & ran on mac in eclipse IDE fine. Same error on linux. It looks like the build on mac and execute on linux only included the jars for mac for lept & tess. Grabbing the cpp bin.zip and replacing the mac jars with the linux ones solve the problem.

To the earlier point, I also installed gcc but I don't think this had any effect here. Though likely would have if I had built it on linux originally instead of building on mac and copying to a linux box.
