Hi All

I created the symbolic link as suggested by Bruce and Luis and still got the error message 

optional        > unable to locate library 'libzint'

in my text editor. I use TeXworks. However, I thought I would try running from the Terminal app and it worked. It found libzint and output the pdf with both barcodes and the qrcode. I have no idea why it works in the Terminal and not TexWorks, I'm guessing I have a path issue which I need to investigate.

Notes
1) My machine is a mac-mini-M1 with macos Monterey and I'm running the latest ConTeXt version
2) Bruce noted that my Homebrew was installed in a non-standard location so I checked on the Hombrew website and it is installed in opt/homebrew for Apple Silicon i.e the M1 chip. Maybe Bruce's homebrew was installed on an earlier version.

Thanks to Luis and Bruce for their suggestions.
Best Wishes

Hi All

I have been struggling today trying to setup and use the Barcode module zint in ConTeXt and failed. I have followed the instructions on the wiki ( https://wiki.contextgarden.net/Barcodes ) but with some changes as follows. Which maybe why I failed.

1) I downloaded Zint using Homebrew since I'm using macOS, and installed it according to the instructions.


2) Since I'm using LMTX I looked for the file libzint.dylib and found it in /opt/homebrew/Cellar/zint/2.10.0/lib . This is different from the path given on the wiki. The directory contained three files, two of which were aliases,  libzint.2.10.dylib and libzint.dylib, and an exe file libzint.2.10.0.0.dylib

You have Hombrew installed in a non-standard location. Mine is in /usr/local/Cellar with the executables linked into /usr/local/bin.

But, assuming other Homebrew commands work when run from Terminal then you might still be okay.

3) I created the path $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint and copied libzint.2.10.0.0.dylib into but replaced dylib with 'so' as suggested on the wiki instructions. So I basically added  lib/luametatex/zint to texmf-osx-64/bin .

"Yes" to creating the path but "no" to copying. Create a symbolic link instead.

So, in Terminal:

  $ cd $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint

  # In my case I used the following:
  $ ln -s /usr/local/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so

  # For you with Homebrew in a different location, try:
  $ ln -s /opt/homebrew/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so

Then steps 4 and 5 as below. I ran the MWE below: the ISBN worked, the ISBNX didn't, the QR code did. This is on Monterey.

4) I ran mtxrun --generate to update the database.

5) I ran the MWE below but no barcode appeared. The console output shows:
 

modules         > using user prefixed file 'libs-imp-zint'
modules         > 'zint' is loaded

 however further down the output it gives:


optional        > unable to locate library 'libzint'

I have tried renaming libzint2.10.0.0.so to libzint.so, but still no barcode. Is their something I am missing? Tips or hints appreciated.
