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 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 . 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.
