Leptonica and Tesseract have to be built by the cross-compiler to be able to build on windows, otherwise, those libraries will not be linked correctly and the package will fail to build properly. |
|
ah... |
How to do on macos，please？ |

he i got undefined: gosseract.NewClientcompilerUndeclaredImportedName client := gosseract.NewClient() my device is windows 11 can help ? |
have the same issue |

Undefined package used when attempting to compile for windows:
I have built a tiny wrapper for Gosseract for my own personal use, but when attempting to compile for windows (on mac) I get an error. There is never an issue and the system works perfectly when compiling for macOS but I get an error without fail when compiling for windows.

main.go.txt
)
The text was updated successfully, but these errors were encountered:
