tesseract build fails after building leptonica from source #555

Open kaisark opened 3 years ago

kaisark commented 3 years ago

I built leptonica from source and everything built successfully. However, when I built tesseract, tesseract build process complains about a linker error (`LeptMsgSeverity' can not be used when making a shared object; recompile with -fPIC).

Is this a tesseract issue or leptonica issue?

Also, I did not see leptonica or tesseract library packages for Ubuntu20. When might these packages (e.g. libtesseract-dev, libleptonica-dev) become available?

Thanks.

Thank you for the report.

This is not a leptonica issue. It might be a tesseract build issue, but I haven't seen it reported before. Please file the issue with tesseract if you haven't done already.

It looks like there was a similar issue already logged under tesseract-ocr: https://github.com/tesseract-ocr/tesseract/issues/2828

Is the issue related to any missing leptonica development headers??? Are there separate build steps for building leptonica with development headers from source (Ubuntu18 package: libleptonica-dev -> "libleptonica-dev is already the newest version (1.75.3-3) )?

stweil commented 3 years ago

Please use the existing packages for Leptonica and Tesseract. You don't have to compile it yourself.

stweil commented 3 years ago

Also, I did not see leptonica or tesseract library packages for Ubuntu20. When might these packages (e.g. libtesseract-dev, libleptonica-dev) become available?

They are available.

Look here: https://packages.ubuntu.com/search?suite=all&arch=any&searchon=names&keywords=libleptonica-dev. Or here: https://packages.ubuntu.com/focal/liblept5

kaisark commented 3 years ago

The packages are available on ubuntu18 and ubuntu20, but were missing from Windows Subsystem for Linux (WSL) - Ubuntu20.

Its probably just a package manager configuration issue.
