ruby-zbar with EPEL zbar doesn't work correctly on CentOS7. #15

Open hiroyuki-sato opened 6 years ago

hiroyuki-sato commented 6 years ago

Hello developers.

Thank you for creating the great product. I would like to share my knowledge on CentOS7.

Summary

ruby-zbar didn't work with libzbar built by EPEL. I needed to build zbar by myself with the patch.

Environment

Build steps

I succeed to build zbar with the following steps in the CentOS7 environment.

remove EPEL zbar 

sudo rpm -e zbar-devel zbar-devel
sudo rpm -e zbar
wget https://astuteinternet.dl.sourceforge.net/project/zbar/zbar/0.10/zbar-0.10.tar.bz2
tar xvf ./zbar-0.10.tar.bz2
cd zbar-0.10
wget https://gist.githubusercontent.com/willglynn/5659946/raw/56e07d934acf8cf5bb5f94a793b74ecc68ebd180/zbar-jpeg-fix.patch
patch -p1 < zbar-jpeg-fix.patch
./configure --disable-video --without-gtk --without-qt
make
sudo make install

After that 

gem install zbar

test code

#!/usr/bin/env ruby

require 'zbar'

Dir.glob("*.jpg") do |image_path|
  r = ZBar::Image.from_jpeg(File.binread(image_path)).process
  r.each do |d|
    next if d.symbology != 'QR-Code'
    puts d.data
  end
end

zbar(EPEL) Error

I got the following errror When I use EPEL libzbar and ZBar
