Linker error on macOS #62

yosefahab commented 6 months ago

I'm having an issue including leptess (also tesseract) into a project. As soon as i include anything i get a linker error complaining about not finding the leptonica, tesseract libraries:

...
= note: ld: warning: search path '"/opt/homebrew/Cellar/leptonica/1.84.1/lib"' not found
        ld: warning: search path '/opt/homebrew/Cellar/libarchive/3.7.2/lib' not found
        ld: warning: search path '"/opt/homebrew/Cellar/tesseract/5.3.4_1/lib"' not found
        ld: library 'lept' not found
        clang: error: linker command failed with exit code 1 (use -v to see invocation)

target: macOS Sonoma v14.4.1 with clang 15.0.0. leptess = "0.14.0"

could it be related to clang version being updated? (similar to https://github.com/ccouzens/tesseract-sys/issues/6) I did clone this repo independently and it worked without any issues though.

Hi, sorry you're having an issue building.

To help debug, can you run:

pkg-config --libs lept
ls /opt/homebrew/Cellar/leptonica/1.84.1/lib

On my work Mac I see

-L/opt/homebrew/Cellar/leptonica/1.84.1/lib -lleptonica

and

cmake
libleptonica.6.dylib
libleptonica.a
libleptonica.dylib
pkgconfig

could it be related to clang version being updated? (similar to https://github.com/ccouzens/tesseract-sys/issues/6)

I don't think it's that precise issue, as that was worked around with this.

I did clone this repo independently and it worked without any issues though.

Is the issue only when leptess is used as a dependency? But you can run cargo test on this repository?

Thanks, Chris

Hello! np we can figure it out hopefully. I'm getting the exact same output as yours.

as for

Is the issue only when leptess is used as a dependency? But you can run cargo test on this repository?

To rephrase, I am unable to compile my project nor run my unit tests. i CAN however clone the leptess repository and run its test cases successfully.

Its important to mention that this is actually a new and sudden thing, however im not sure what would cause this (a version upgrade or something completely unrelated to this project)
