The sample demonstrates how to create a Ruby barcode reader on Mac OS X 10.10.5 with Dynamsoft Barcode C/C++ SDK (DBR).

Dynamsoft Barcode SDK

1. Generate Makefile with

   ruby extconf.rb
   

2. Open Makefile and change configurations.

   • Dynamsoft Barcode include directory:

   dbrdir = /Applications/Dynamsoft/Barcode\ Reader\ 3.0\ Trial/Include
   
   INCFLAGS = -I. -I$(arch_hdrdir) -I$(hdrdir)/ruby/backward -I$(hdrdir) -I$(srcdir) -I$(dbrdir)
   

   • Dynamsoft Barcode dylib:

   LIBS = $(LIBRUBYARG_SHARED)  -lpthread -ldl -lobjc -lDynamsoftBarcodeReader
   
   

3. Run make. If you get the warnings:

   ld: warning: directory not found for option '-L/usr/local/lib'
   

ld: warning: directory not found for option '-L/usr/local/lib' ``` Open Makefile and change ldflags = -L. -L/usr/local/lib to ``ldflags = -L. -L/usr/lib``. If there's no warning, you will see ``linking shared-object dynamsoftbarcode.bundle`` 4. Run ``sudo make install`` to copy dynamsoftbarcode.bundle to /Library/Ruby/Site/2.0.0/universal-darwin14 5. Run Ruby script:

```
ruby barcode_reader.rb barcode_file
```
