Cannot link gosseract v2.2.1 on masOS: ld: library 'lept' not found

I have installed tesseract 5.3.4 and leptonica 1.84.1 from homebrew. When I'm trying to run even the simplest code:

package main

import (
    "github.com/otiai10/gosseract"
)

func main() {

    client := gosseract.NewClient()
    _ = client

}

I get the following error:

/opt/homebrew/Cellar/go/1.22.1/libexec/pkg/tool/darwin_arm64/link:

running c++ failed: exit status 1

ld: warning: ignoring duplicate libraries: '-llept', '-ltesseract'

ld: library 'lept' not found

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've searched through all cmake files related to tesseract and leptonica and couldn't find linker options like -llept. Also leptonica brings shared libraries like libleptonica.6.dylib not liblept.6.dylib, but even making corresponding symlinks doesn't help.

Is there any something else I'm missing which is required to make gosseract work on masOS Sonoma with go1.22?

Solution

Changing the github.com/otiai10/gosseract/client.go from:

// #if __FreeBSD__ >= 10
// #cgo LDFLAGS: -L/usr/local/lib -llept -ltesseract
// #else
// #cgo CXXFLAGS: -std=c++0x
// #cgo LDFLAGS: -llept
// #endif
// #include <stdlib.h>
// #include <stdbool.h>
// #include "tessbridge.h"

to:

// #if __FreeBSD__ >= 10
// #cgo LDFLAGS: -L/usr/local/lib -lleptonica -ltesseract
// #else
// #cgo CXXFLAGS: -std=c++0x
// #cgo LDFLAGS: -lleptonica
// #endif
// #include <stdlib.h>
// #include <stdbool.h>
// #include "tessbridge.h"

Did the trick. The problem here is if you choose to do so as well, you'll have to vendor this module in your application and support your version yourself.

As I mentioned in my question, I installed tesseract and leptonica using homebrew. It doesn't touch anything in /usr/local. I made a symlink /usr/local/lib -> /opt/homebrew/lib in order not to edit gosseract itself further, so this may be not a very good solution.

UPDATE:

In github.com/otiai10/gosseract/v2 (latest version as of 2024-03-06 is 2.4.1) has the -llept issue sort of fixed, however it is still necessary to synmlink /usr/local/lib to /opt/homebrew/lib
