It looks like unicharset_extractor.cpp is the only place that std::filesystem::path is used and that was introduced relatively recently: https://github.com/tesseract-ocr/tesseract/commit/8a26329623a017277364bc5670266c7e964c8a07?diff=split&w=1 so it probably wouldn't be hard to restore compatibility with older systems, but you're likely living on borrowed time.
If you want to try fixing this locally, you could replace path.extension() with string.compare() Tom -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
