[SOLVED] Is there a package containing a QR decoder?

RandomTroll · 06-30-2024, 07:16 PM

I wanted to decode a QR code. I found qrencode, which encodes them, but no decoder. I built zbar, which seems to be the favorite decoder. Did I miss Slackware's?

A web search for "decode qr code linux" turns up a number of articles.

This one looks like a good starting point.

I did take a look at Slackbuild.org and my search did not turn up a QR decoder.

Those top searches and that blog post all use zbar.

I've used zbar for barcode scanning and it works for qr codes as well. Seems like its pretty much the standard when looking for a linux solution. There is no qr code/barcode decoder packaged with Slackware afaik, just zbar on slackbuilds.org.

I also only use zbar, I don't think slackware has anything like that first party.

In -current there's zxing-cpp package which contains ZXingReader and ZXingWriter CLI tools. I just tried them (never used them before):

Code:

$ ZXingWriter -size 200x200 QRCode Slackware qr.png
$ ZXingReader qr.png

I see this is marked solved. What solution was the answer?

Thanks! I just installed it for the first time and it worked - and gave a more-complete decode than zbar.

I started the thread expecting the answer to be that there was none, because I thought I had looked enough; I was alerting Slackware's keepers to the matter, in case they cared, so it was 'solved' by raising the issue. But audriusk provided a real answer afterwards.
