Golang Barcode Reader for Windows

The sample demonstrates how to create a Golang Barcode Reader by wrapping Dynamsoft Barcode Reader SDK with SWIG on Windows.

Download & Installation

• mingw-w64
• SWIG
• Go
• Dynamsoft Barcode Reader

Basic Steps

1. Set GOPATH as the location of your workspace. E.g. set GOPATH=f:\go-project

2. Create your package path. E.g. mkdir %GOPATH%\src\github.com\dynamsoftsamples\go-barcode-reader\dbr

3. Copy DynamsoftBarcodeReaderx64.dll to %GOPATH%\src\github.com\dynamsoftsamples\go-barcode-reader\dbr\bin

4. Change directory to %GOPATH% and compile the package with go install github.com\dynamsoftsamples\go-barcode-reader\dbr. Alternatively, you can change directory to %GOPATH%\src\github.com\dynamsoftsamples\go-barcode-reader\dbr and compile the package with go install.

5. A package dbr.a will be generated at %GOPATH%\pkg\windows_amd64\github.com\dynamsoftsamples\go-barcode-reader.

6. Create %GOPATH%\github.com\dynamsoftsamples\go-barcode-reader\BarcodeReader\BarcodeReader.go .

   package main
   
   import (
     "github.com/dynamsoftsamples/go-barcode-reader/dbr"
     "os"
   )
   
   func main() {
     if len(os.Args) == 1 { // read the default image
       dbr.Decode_file("AllSupportedBarcodeTypes.tif")
     } else {
       dbr.Decode_file(os.Args[1])
     }
   }
   
   

7. Copy DynamsoftBarcodeReaderx64.dll to %GOPATH%\bin.

8. Change directory to %GOPATH% and run go install github.com\dynamsoftsamples\go-barcode-reader\BarcodeReader.

9. Read a barcode image with %GOPATH%bin\BarcodeReader.exe <barcode image>
