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.
Best Wishes
