# Building 1D/2D Barcode Reader with C++ and CMake
This repository contains examples demonstrating how to utilize the **Dynamsoft Barcode Reader SDK** to build barcode and QR code detection applications with C++ and CMake on **Windows**, **Linux**, **macOS**, and **Raspberry Pi OS**.

## Prerequisites
- Obtain a [30-day free trial license](https://www.dynamsoft.com/customer/license/trialLicense/?product=dcv&package=cross-platform) for Dynamsoft Barcode Reader.

    ```cpp
    CLicenseManager::InitLicense("LICENSE-KEY", szErrorMsg, 256);
    ```

- OpenCV Installation
    1. Download [OpenCV](https://opencv.org/releases/)
    2. Configure the environment variable `OpenCV_DIR` to the path of the OpenCV installation directory.
    3. Add the following lines to the `CMakeLists.txt` file:
    
        ```cmake
        # Find OpenCV, you may need to set OpenCV_DIR variable
        # to the absolute path to the directory containing OpenCVConfig.cmake file
        # via the command line or GUI
        find_package(OpenCV REQUIRED)
        ```

## Supported Platforms
- Windows x64
- Linux x64/ARM64
- macOS x64 (Intel/Apple Silicon)

## How to Build a CMake Project

**Windows**

1. Create a **build** folder:
    
    ```bash
    mkdir build
    cd build
    ```

2. Configure and build the project:
    
    ```bash
    # x86
    cmake -DCMAKE_GENERATOR_PLATFORM=x86 ..

    # x64
    cmake -DCMAKE_GENERATOR_PLATFORM=x64 ..
    
    cmake --build . --config release
    ```

    For `MinGW`:
    
    ```bash
    cmake -G "MinGW Makefiles" ..
    ```

**Linux and Raspberry Pi OS**

1. Install **CMake**:
    
    ```bash
    sudo apt-get install cmake
    ```

2. Create a **build** folder:
    
    ```bash
    mkdir build
    cd build
    ```

3. Configure and build the project:
    ```bash
    cmake ..
    cmake --build . --config release 
    ```

**macOS**
 
1. Install **CMake**:
    
    ```bash
    brew install cmake
    ```

2. Create a **build** folder:

    ```bash
    mkdir build
    cd build
    ```

3. Configure and build the project:

    ```bash
    cmake ..
    cmake --build . --config release 
    ```
