Hi @adminSxs,

I'll try building on Windows 10 tonight.

Have you already installed Microsoft's vcpkg and run .\vcpkg install tesseract:x64-windows?

yes image

Ok, I'll try in Windows 10 tonight and see what needs to be done

Ok,thanks.

Sorry if I'm not very useful at this issue. I don't use Windows much.

There seem to be 2 errors.

cargo:warning=couldn't execute `llvm-config --prefix` (error: 系统找不到指定的文件。 (os error 2))
cargo:warning=set the LLVM_CONFIG_PATH environment variable to a valid `llvm-config` executable

--- stderr
thread 'main' panicked at 'Unable to find libclang: "couldn\'t find any valid shared libraries matching: [\'clang.dll\', \'libclang.dll\'], set the `LIBCLANG_PATH` environment variable to a path where one of these files can be found (invalid: [])"', D:\software\cargo\registry\src\github.com-1ecc6299db9ec823\bindgen-0.52.0\src/lib.rs:1895:13

It can't find llvm-config and it can't find clang. These are usually installed together.

Can I get you to try installing LLVM? https://releases.llvm.org/download.html https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.0/LLVM-10.0.0-win64.exe

If this works, I'll update the Readme to include this step.

i'm win10 os

I use centos:7 to build

How are you using Windows 10 and CentOS 7 at the same time to build leptess?

rucoder commented 3 years ago

On windows, LLVM doesn't provide llvm-config. You must set LIBCLANG_PATH environment variable to \bin folder For example, I'm using this In my launch.json

    "tasks": [
        {
            "type": "cargo",
            "command": "build",
            "problemMatcher": [
                "$rustc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "options": {
                "env": {

@ccouzens Hello, I don't mind if you forward windows build related issues to me in the future. I'm not monitoring this repo constantly so just mention my name in the message so I'll get a notification

ccouzens commented 3 years ago

Hi @rucoder - thank you- I'll do that in future :smile:

I may have resolved this -- or hit an error in the process of 'fixing' it -- will move that error to the leptonica-sys repo as that's the source..

@ccouzens I have solved the clang problem by installing llvm via the winget tool. it will then find the dll automatically. However, I am now a step further but I get linking errors. Both dynamically and statically. Do you have any idea how to fix this?

I am on windows 11.

For example, I used:

# To install the LLVM (clang)
winget install LLVM

# the vcpkg dependencies
.\vcpkg.exe install tesseract:x64-windows-static
.\vcpkg.exe install leptonica:x64-windows-static

# the linker initially fails, so updated this to be windows msvc
rustup default stable-x86_64-pc-windows-msvc

cargo config

[target.x86_64-pc-windows-msvc]
rustflags = ["-C", "target-feature=+crt-static"]

The only dependency I have is leptess cargo toml

[dependencies]
leptess = "0.14.0"

This is the error I get when building:

   Compiling rstool v0.1.0 (C:\Users\mario\source\repos\rs-tool\rstool)

There's a weird workaround in windows. Add openssl as your dependencies and on top of your main.rs add use openssl. somehow this works for me or. But this way, Clippy will complain. To shut them up. Re-Export openssl.

so this is my program. It compiles on windows:

main.rs

const IMAGE_PATH:&str = "test1.png";

mod ocr_wrapper;
use ocr_wrapper::ocr;

fn main() {
    let text = ocr(IMAGE_PATH).unwrap();
    println!("{}",text);
}

ocr_wrapper.rs

use leptess::LepTess;

pub use openssl; //this is necessary

pub fn ocr(image:&str)->Result<String, std::str::Utf8Error>{
    let mut ocr = LepTess::new(None, "eng").expect("Load OCR Fail");
    ocr.set_image(image).expect("Error Reading Image");

    ocr.get_utf8_text()

}

Cargo.toml

[dependencies]
leptess = "0.14.0"
openssl = "0.10.57"

i'm a novice on compile, maybe this crate can add openssl when use static link. i see the error is about openssl.
