Go build fails on windows 10 (undefined reference)
Fentonz opened this issue · 2 comments
Summary
I cant get gosseract to work on Windows10. I managed to build tesseract and leptonica with VS 2019, but I had issues with pathing in many header files. I solved that by adding absolute path to those header files like this:
But now it seems like I have an "undefined reference" issue when calling "go build". I have no idea what to do...
Reproducibility
Build tesseract and leptonica with VS 2019 on windows 10. Add absolute paths to headers. Go build an example file with gosseract package.
Reproducibility Frequency
- 100% i guess, cant get it working :)
Environment
Gosseract version: main (2762ecf)
OS: Windows 10 64-bit
Tesseract and leptonica compiler: Visual Studio 2019 (CMake)
