c++ using tesseract api built with visual studio 2019 on windows 10 crashes on windows server 2012 #3048

Im am using the tesseract api (version 4) in a c++ program and build it using visual studio 2019 on windows 10. The executable runs fine on other windows 10 machines, but on windows server 2012 it crashes. The c++ runtime is correctly installed, other c++ programs work fine.

If your Windows server is an older machine which does not support AVX, this might be a duplicate of issue #3044.

jonaumann commented 4 years ago

yes, might be the same issue as #3044. How can I fix this? Can I just swap the tesseract dlls with the ones from the UB Mannheim binary build for windows? In the related issue it was said that this version does not have the problem?

I'm afraid that won't work, because UB Mannheim uses the GNU compiler, so the generated DLL is not compatible with MS Visual Studio code. The right solution would require fixing cmake builds and do a fresh build with the MS compiler.

jonaumann commented 4 years ago

Ok. How do I change the build? I was using vcpkg tool to install tesseract dlls. How can I proceed?

@jonaumann, please try the latest Tesseract code and report your result. Hopefully it has fixed this problem.

jonaumann commented 4 years ago

I don't have the expierence to build tesseract from scratch on windows. But thanks for your efforts! Hopefully Microsoft in the future will offer version 5 for vcpkg. In the meanwhile I use the tesseract.exe from UB Mannheim that works on windows server 2012.
