Yep, I catch this bug. Qt 5.12 + mingw73_64 The problem is - you are trying to call tesseract::Dict::GlobalDawgCache() which is not exported from dll. I’m realy messed, why even MSVC didn’t catch this bug, maybe due to it is a static function and somehow linker could get the definition, also I don’t remember that this bug was appearing a year ago even with MinGW. So, just add TESS_API to the Dict: src\dict\dict.h

   class TESS_API Dict {

Probably other objects may need to be checked for missing TESTS_API.
